iPhone Antenna Repair


iPhone with a repaired antenna 

 

The antenna is a component that allows your iPhone to connect to your carrier’s cellular and LTE network.

 

 

 

If you drop your phone or it gets something spilled on it, the antenna can get damaged. The antenna cable can break or disconnect from the logic board, creating a problem with the signal.

If people you call complain that you are “cutting out”, or you find that you only have 1-2 bars beside the carrier’s name, or the dreadful “No Service” message – you should bring your iPhone to one of our locations in Toronto or Mississauga to get your cellular antenna replaced.

Our trained technicians can do the antenna replacement on your iPhone within an hour, while you enjoy a coffee and Netflix in our lounge!

It can be frustrating to have a phone with a damaged or malfunctioning antenna, because the antenna controls many of the functions that make cell phones such an important part of many people’s lives. Simple tasks such as making and receiving phone calls, sending text messages or using your cell phone service provider’s LTE network suddenly become annoying or impossible when your cell phone has a broken or damaged antenna cable.

The antenna cable in the iPhone is connected to the rest of the internal “guts” of the phone, which is called the logic board, and if the connection holding the antenna to the logic board becomes damaged or broken, you might experience issues such as:

  • dropped calls,
  • calls where the person on the other side of the call complains you are cutting out,
  • a “No Service” or “Emergency Service Only” message where the signal strength bars should be,
  • only 1 or 2 signal strength bars filled instead of 4 or 5, or
  • you are unable to connect to LTE or 3G networks.



iPhone Bluetooth Repair


an iPhone that has lost Bluetooth connection that has been repaired

 

Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices, and building personal area networks.

 

 

 

Bluetooth is an effective way of connecting your cell phone wirelessly to a wide variety of devices such as:

  • Hands-free headsets
  • Car stereo or GPS systems
  • Wireless headphones or speakers
  • Wireless keyboards
  • Home security devices such as locks or alarms
  • Other mobile devices like laptops, tablets or cell phones
  • And many other applications.

This cordless technology works using radio waves like an FM radio transmitter would, but instead of the signal travelling hundreds or thousands of kilometers to your radio or phone or TV, the radio waves only need to travel a short distance, usually a minimum of 10 metres, but can be stretched to more than 100 metres. This might seem like a limitation, but it is actually a good thing, as it keeps the power usage of the device low.

Enabled media devices use these waves to connect through constantly refreshing networks called “piconets”. Devices connected to one another are a “pairing”, or are “paired”.

These networks are kind of like rubber bands. Devices are automatically connected when in range (which is not like a rubber band but this is totally going somewhere relevant.) and the network can stretch to accept multiple devices (see? Exactly like a rubber band.). Each rubber banded device can also communicate with a maximum of seven other devices which can each be rubber banded to seven more, etc., etc. Devices can also be attached to multiple networks at once. This means users can connect Bluetooth devices in endlessly customizable ways to make the most of their electronics.

This hands-free technology makes using a cell phone while on the go much handier (pun intended!). Tasks like driving which would be dangerous to do while using a cell phone in one or both hands, suddenly become safer and simpler.



iPhone Home Button Repair


The home button may actually be the most important button on your iPhone and probably the button you use the most!

It’s the button you click to go back to your home screen. If your home button becomes damaged or broken, you won’t be able to do many things easily as you were before. You’ll still be able to do things, it will just take much longer to do so. So if your iPhone home button is sticking or simply not working at all, bring it in and we can replace it for you in 1 hour.

On iPhone models that are equipped with Touch ID (fingerprint unlock) the home button itself contains electronics that assist in sensing your fingerprint and unlocking the iPhone.  The home button is matched 1 to 1 with the mainboard of the iPhone.   

After a home button replacement on an iPhone with Touch ID the fingerprint sensor will no longer operate.

 

Evolution of the iPhone Home Button

The iPhone 5 and 5S models and up came with the home button doubling as a fingerprint scanner, called “Touch ID”,

Touch ID allows you to unlock your phone with your fingerprint instead of typing in a password, and also allows you to purchase apps, movies, or music without needing to verify your credit card every time. This is also beneficial for preventing credit card fraud or accidental purchases if you have small children who often use your phone for “pay-to-win” type games or apps, because you can require your phone to ask for a fingerprint scan before completing a purchase.

As of the iPhone 7 model iPhones don't come with a mechanical Home button like previous generations.

Instead, it comes with an all-new pressure sensitive Home button, which relies on the Taptic Engine to give you a sensation that you have clicked on the button. Pressure sensitive buttons have their advantage. You no longer need to worry about the wear and tear of the home button. Apple used the words “force sensitive solid state” – which means, in a sense, that it’s a lot less prone to breaking or wearing out.

The iPhone X doesn't have a separate home button component at all.  Consequently it does not have Touch ID fingerprint security.

 

More About Home Button Touch ID

Touch ID works by layering a few different components on top of each other. The top layer made of a very scratch-resistant sapphire crystal (I guess you could say Apple craves that mineral!).

This layer needs to be scratch-resistant because any imperfections on the scanner can prevent Touch ID from scanning fingerprints properly. Then a stainless steel ring surrounds the crystal which when touched by your finger (your body has low levels of electricity – ‘cuz baby you’re a firework!), “wakes” the actual fingerprint sensor underneath.

This sensor “reads” your fingerprint by taking a very detailed picture of your fingertip and matching it to a scan saved to your phone.

Apple assures their users that the fingerprint data isn’t saved anywhere but on the phone itself, not on their servers or online. This should make the fingerprint data safer from security threats or hacking.

The touch software is programmed to request a pass code or password in certain situations before it will re-enable the scanner, for your security:

  • If Touch ID hasn’t been activated in more than 48 hours,
  • If your phone has been recently rebooted or reset to factory settings,
  • If your phone has failed to read your fingerprint correctly 5 times in a row, or
  • If you’ve remotely locked your phone using an app like Find my iPhone (usually if it has been stolen or lost).

The Touch ID can also help replace your wallet with a new program called Apple Pay, a “contactless payment” system. It is available at some places in the US, but not currently in Canada. Apple has plans to bring Pay to Canada some time in 2015.

This software allows users to quickly tap their phone against the credit card terminal at a variety of places, instead of swiping their credit card or entering their PIN. It also works with a huge range of online stores and apps. Apple Pay also allows you to store more than one card, just like your actual wallet.

“Banks are clamping down on their verification processes for the Apple Pay mobile-payment system after crooks started loading stolen credit-card data onto phones and then making fraudulent purchases...The banks are making customers jump through more hoops because they want to make sure that card really belongs to the person who is loading it into the phone.”

--Wall Street Journal, March 2015.

The iPhone 6 Plus’ large size meant Apple needed to add an additional function to this phone, called “Reachability”. The large screen-size makes touching all parts of the phone when holding it in one hand difficult for some users. By double-tapping the home button, everything on the screen is shifted to the bottom half for greater ease of use. This function works, regardless of whether you are:

  • in a third-party app,
  • on the home screen,
  • surfing the internet, or
  • using any other function on your phone.

Without a working home button, you will not be able to use your phone for a lot of the things you usually use a phone for, such as:

  • returning to the Home Menu from a web browser or app
  • using Touch ID to make purchases
  • unlocking your phone’s screen with a fingerprint scan

Once your iPhone’s home button works, you will be able to:

  • Capture screenshots of what is displayed on your phone (press the home button and the power button at the same time)
  • Make secure credit card purchases and bank payments online with a swipe of your fingerprint
  • Exit out of apps or other open windows quickly
  • Use voice commands and access Siri for searches, contacts and more
  • Bring up all open apps in the “multitasking” window (press the home button twice to use this option)
  • Open up your list of recent calls and favourite contacts (double click the home button to find this list)

With such an important part of your phone out of commission, you will definitely find using your phone much more difficult. Bring it in to the Techknow Space and walk out within an hour with it back in action.



iPhone Mute Button Repair


The iPhone has the mute button or sometimes known as the silent mode switch typically right above the volume buttons, it is important for switching your ringer off so the phone will vibrate when a call comes in.

If the mute button doesn’t work, you may not be able to hear when you receive a phone call.

The mute switch might not seem like an important part, but using your phone without can get pretty inconvenient at times. Phones are meant to make your life easier, not more difficult – so why live with a device that doesn’t work 100%?

Come to The TechKnow Space and let the experts fix your iPhone mute switch within the hour, and allow you to enjoy the benefits of a working mute switch:

  1. Allow you to attend meetings without interruption.
  2. Snooze at night with no annoying notifications or call from different time zones.
  3. Enjoy movies and other public entertainment without aggravating the “public” around you.
  4. Now that airlines allow in-flight mobile use, let your co-passengers enjoy their quiet meditation, work, or rest.

Living without a working mute switch can get really inconvenient – just imagine going into the settings of your iPhone to mute it every time you are sitting in class, library, going to the movies or theatre where you need to mute the phone! It’s definitely much easier to do that by just flipping the mute switch. If your iPhone mute switch needs to be repaired – bring it in to our expert repair gurus who will replace it while you wait in our comfy lounge drinking coffee and watching TV!



iPhone Proximity Sensor Repair


Q: What is an iPhone proximity sensor?

A: The iPhone proximity sensor is the component in the iPhone that turns the screen (display and touchscreen) off while holding the phone to your ear while on a call to prevent the touchscreen from disconnecting the call or activating any other function.


The proximity sensor rarely fails on its own.  It is common however for the proximity sensor to break as a result of damaging your iPhone screen.

Troubleshooting Common iPhone Screen Problems


Cracked or broken touchscreens, LCDs, and glass are the most common problems with any iPhone. Many people mistakenly believe that Gorilla Glass is unbreakable, which is not true. Corning Gorilla Glass on an iPhone is a great improvement, making it less easy for the digitizer or screen to get scratched, but it is still easy for the screen to crack or break.

Often, the digitizer or the LCD part of the iPhone screen may not be visibly broken, but does fail to work due to repeated knocks, dings and drops. So, while the glass screen has no visible crack, it might be white or unresponsive to the touch. After suffering multiple knocks and drops over time, just the slightest impact may render it inoperable. This is a perplexing but common experience for many users who can’t understand why a very slight impact resulted in the failure of their touchscreen..

A damaged LCD can also be bleeding the liquid that is sealed within it. This impact often results in hair-line cracks that are often invisible to the naked eye. Over time, however, repeated knocks can widen and deepen the cracks until they are large enough to seep out liquid.

Using your iPhone with a partially non-responsive or a fully dead screen is very frustrating. It means you can’t access a portion of your apps or are not able to see any display at all!

 

Outer Screen (associated with the iPhone digitizer, glass, or the touchscreen) problem symptoms include:

  • not responding to your touch
  • glass is cracked or broken
  • glass moves downwards when touched
  • You can’t “slide to unlock” 
  • The screen is badly scratched and difficult to see through

Your iPhone’s LCD will likely need to be replaced if you experience of the following:

  • Cannot see any image on the screen
  • The screen is displaying lines
  • The display is intermittent
  • The display has bleeding (the liquid in the Liquid Crystal Display is bleeding through the hairline cracks in the LCD glass.
  • The screen is dark/black 

For any of the above, your screen assembly needs to be replaced. Bring your iPhone to The TechKnow Space and let our expert technicians replace the screen within an hour.

Further Damage not Addressed by a Screen Replacement

Typically, your display or LCD gets damaged because of a hit, bang or a drop. When this happens, you are unable to use your iPhone since you cannot see what is displayed on the screen. It is possible that the bang or the ding has also damaged other components on your iPhone, like your headphone jack, loudspeaker, earpiece, wifi antenna, etc. We can often only discover these failures once we have replaced the screen, and can observe the behaviour of your iPhone functions on the display. Should we identify any additional repairs needing to be done to your iPhone, we will call you for confirmation before completing any repairs. 

In situations where your iPhone screen is not the only problem we may need to perform additional diagnostic work to determine the cause of the problem and the repair approach which can take more than an hour and sometimes up to a day.  (We will always keep you posted during the repair process!)

Frame Damage

Sometimes when the drop that damages your iPhone screen also causes damage to the frame as well. The iPhone’s case may become dented, bent and otherwise deformed, preventing the new replacement screen from being installed properly.

It is crucial to address the issue with the frame before installing the new screen, as doing the installation on an imperfect frame could cause stress on the glass, and make the screen crack with a minimal amount of force applied to it.

In the event if we find damage that requires some minor adjustment, we will perform the repair at no extra charge to you. If the frame is severely deformed (and sometimes that can only become evident after the cracked screen is removed) we will call you and inform you of an additional charge (typically less than $20) for realigning the frame and with the costs of replacing the housing entirely.

Again, when we discover any issues with your device beyond just a screen replacement, we will inform you and ask for your confirmation before we do any iPhone screen repairs.

A Review by Mike Wakunick

"This place offers exceptional service for an affordable price. I've been here twice over the last 3 years (iPhone 4 screen repair). They quoted me the standard 1 hour service for the repair to be completed, and it was finished within 20 minutes. As we all know, it's imperative to have our mobile devices working top notch, and we cannot be without them for a week while they are sent in to some unknown location to be repaired. TechKnow space is trustworthy, and you will get your device back the same morning or afternoon - 1 hr for phones and 2 hrs for tablets. They even have a customer lounge area with free wi-fi and a large screen TV for you to use while you wait for your repair to be done. Otherwise, you can leave and come back. Always have had great experiences with TechKnow Space, and will continue to be a customer here in the future! :)"

Breakdown Of The iPhone Screen By Layer and Repair Statistics


An iPhone screen needs to be replaced when either one of the two components has sustained damage:

  1. The outer screen: This is also referred to as the Touchscreen or Digitizer or the Glass.
  2. The inner screen: This is also referred to as the Display or the LCD.

The original first 2 iPhones came with two screen components installed separately.

All other iPhones come with the two screen components fused together as one complete assembly making them impossible to repair individually. Apple has decided to do this for several reasons:

  • With a fused touchscreen and LCD there is never an issue with dust getting in between the layers of the screen

  • The screen is thinner, as there is no air gap between the digitizer and the LCD. This allowed Apple to make iPhones a little thinner overall

  • The thin iPhone screen makes the colors of the LCD look more vibrant and the image clearer.

In our experience we have learned that the primary reason for iPhone Screen Repairs is broken glass, followed by LCD only broken, and in the fewest cases we have seen screen failure without any visible damage or breakage - see the breakdown by failure in the following chart:

iPhone Screen Repairs - Breakdown by Screen Layer

iPhone Screen Repairs vs All Other Component Repairs

Repairing The iPhone Glass & Touchscreen


For the top layer of any iPhone screen there’s a layer of Corning’s Gorilla Glass. It’s a specially treated toughened glass designed to withstand drops and dings in order to prevent the glass from getting cracked or scratched.

During its manufacture, the glass is toughened by ion exchange. The material is immersed in a molten alkaline potassium salt at a temperature of approximately 400 °C, wherein smaller sodium ions in the glass are replaced by larger potassium ions from the salt bath. The larger ions occupy more volume and thereby create a surface layer of high residual compressive stress at the surface, giving the glass surface increased strength, ability to contain flaws, and overall crack-resistance, making it resistant to damage from everyday use.

Just keep in mind that as resistant as it can be, it is still glass.

The glass is a part of your iPhone’s screen not because smartphone manufacturers want to make phones particularly frail or weak, but because it is an important part of how the screen reacts to touch.

Touchscreens on all cell phones use a technology called “capacitive sensing”. This uses a layer of glass as an insulator (which means it does not transmit electricity), coated with a conductor (which can transmit electricity).

The conductive layer is usually a combination of metals called “indium tin oxide” (ITO). These metals are transparent, so you can see what is being shown on the display underneath.

Because the human body is also an electrical conductor, when your fingers make contact with the touchscreen, the conductive coating registers this as a change in the iPhone screen’s electric field. This is how your iPhone knows where you are tapping or dragging on the screen itself, even if you use multiple fingers at the same time.

Touchscreens use a series of steps to process the information entered by touching your iPhone’s screen:

  • Your iPhone registers touch by analyzing the area of the iPhone screen interrupted by electrical impulses (finger, stylus, etc.) for size and location.
  • iPhone software inputs the data taken from the touchscreen and calculates the features of the gesture.
  • The software combines the touch with the application in use and carries out the action and sends out additional information if necessary to other parts of your iPhone’s screen or extra hardware.
  • If the software completes the process and can’t match a gesture with an action, your iPhone will ignore the touch as an accidental input.

All of this happens almost instantly. In fact, you probably will never notice a delay between touching the screen and the action happening. Not only can your iPhone do all of that in a nanosecond, but it can also calculate multiple touches at once, like two finger gestures such as zooming in.

You might think that touchscreens having a “multi-touch” capability is new technology. And it is pretty new, relatively speaking. In 1982, a group from the University of Toronto created a screen made of a camera behind a pane of glass which could register any human input. This awkward and hard to use interface was improved by U of T in 1985 with the first version of the modern touchscreens we know and love today.

Apple claimed they invented the multi-touch technology in 2007 with the release of the first iPhone, but both the phrase “multi-touch” and the actual function itself existed well before the rise of the iPhone. However, they are not being completely dishonest, as Apple holds several patents for the mobile device version of the technology.

Apple prides itself on user friendliness, and the iPhone screen interfaces with users in a very natural and intuitive way. The iPhone touchscreen can register your finger or stylus regardless of pressure or surface area. That is to say, the iPhone’s screen is sensitive enough that pressing hard or with a wider stylus isn’t necessary for accuracy or effectiveness.

The gestures accepted by the iPhone touchscreen are also very natural-feeling. Using multi-touch gestures to do a variety of movements, such as scrolling the screen, or expanding or shrinking the screen’s contents are often naturally understood by the user.

Repairing The iPhone LCD & Back-light


Most smartphones use LCD technology for screens because it is thin and relatively cheap when compared to its lifespan.

The display of your iPhone is a high definition “liquid crystal display” or LCD for short. Liquid crystals might sound like something impossible, because how can something be both a liquid and a solid at the same time? But because these crystals can do both at the same time, the result is a screen which can display millions of different colours with no visible delay.

These liquid crystals are laid out in between two pieces of polarized glass, underneath the touchscreen. This layer is then powered by thin wires laid out in a grid underneath the crystals.

The crystals act like shutters, opening and closing above a colour filter composed of tiny red, green, and blue “sub-pixels.” These sub-pixels are invisible to the naked eye, and can be brightened or darkened in over 16 million combinations to create crisp, vibrant images and text.

The crystal component of the LCD is only half of the equation. The liquid crystal layer doesn’t project any light on its own, so your iPhone needs a layer of lighting (usually small, low-powered LEDS). This layer of lights is underneath the rest of the components and is referred to as backlight.

 Starting with the iPhone 4, Apple calls the new screen technology a “Retina HD” display:

“Rather than using traditional methods to create the higher-resolution Retina HD display, we developed an advanced process of photo alignment. This involves using UV light to precisely position the display’s liquid crystals so they lie exactly where they should. Better-aligned crystals deliver a superior viewing experience.”

Their new technology promises a few interesting perks, like increased visibility in direct sunlight or with sunglasses on. Another added functionality of the Retina HD display in the latest iPhones is a wider viewing angle. The “viewing angle” is the largest angle that the display can still be acceptably used at.

Apple says the screens can now be comfortably viewed from almost any angle. This is possible because of the screen’s higher contrast and extra pixels.

iPhone Touch ID Fingerprint Sensor Failure After Screen Replacement


Problem:

Touch ID Fingerprint Sensor not working after screen replacement on an iPhone 6.

 

When does this happen?

It is a very rare occurrence -- about 1 out of 1000 screen replacements on average.

 

Are any iPhone models more susceptible to this failure?

The iPhone 6 Plus (as acknowledged by Apple), the iPhone 6 and 6S are more likely to exhibit this Touch ID issue than are other models.

 

Why does it happen?

There are a number of possible reasons why this particular issue may arise:

1.  Damaged Home Button Cable:

An easily diagnosed problem - damage to this cable can be seen with the naked eye. 
This damage is not repairable and can only be addressed by Apple (phone replacement for a fee).

2.  Damaged Home Button Extension Cable:

This cable runs from the bottom of the iPhone to the top between a heat-shield and the iPhone LCD.
The extension cable is not usually replaced with a screen (on iPhone 6) as damage to this cable infrequent.
The screen assembly frame must be disassembled to remove this cable and replacement usually solves the problem.
This problem is repairable.

3. Damaged Main-board Circuits:

After impact the behavior and reliability of electronics will ALWAYS be questionable.  
Apple has acknowledged main-board failure on some models under less severe circumstances than screen breakage.

Touch ID failure can happen after a screen replacement (even if it was working after the breakage) for the following reasons:

During screen replacement - the home button must be disconnected from the main-board.

After reconnecting - underlying main-board failure begins to exhibit the symptom of Touch ID not working.

Even after reconnecting the original screen the Touch ID failure can persist.
Disconnecting the battery and disconnecting the components necessary for the screen replacement can result in capacitors on the main-board which were previously constantly conducting electricity and maintaining a charge to drain their electricity and exhibit failure when the power is re-connected.

The only option is replace the phone.

4. Damaged Connectors:

This is most common after liquid damage exposure.
Liquid corrodes the conductive pins on the connector.
This is sometimes repairable.

The volume buttons on your phone are a small but important part of your device. Imagine being unable to adjust the sound while watching movies or listening to music!

You probably never think about the volume buttons. But once they stop working properly, your phone might suddenly seem very frustrating.

Now you can’t change the volume while making or receiving a call, or asking Siri something, among other things. That might seem like something you can live with, but it will more than likely get annoying fast.

If the volume buttons are not working properly, or even worse – not working at all, let the experts at the Techknow Space get your iPhone back to full health in no time.

  • Snapping selfies and other memorable moments with the touch of a button

  • Silencing the ringer quickly when your phone goes off during an important meeting or the dramatic climax of a Broadway play

iPhone Wont Power On Diagnostics


iPhone that won't turn on fixed 

 

If you are worried your new iPhone is destined to become a very expensive and fancy paperweight because it won’t turn on, don’t worry.

 

 

There are a few things you can do to try to fix the problem, but if those don’t work, the in-house expert technicians at the Techknow Space can definitely help!

If your iPhone won’t turn on, try to restart it by holding down the power button on the side of your iPhone (referred to sometimes as the hold or lock button, and by Apple as the “sleep/wake” button.) until the screen lights up. If this doesn’t occur, try plugging your iPhone in and waiting about 15 to 20 minutes before trying again.

But if this doesn’t solve the problem, you can try doing a hard reset by holding down the power button and the home button (on the front of the screen) together. You will probably need to hold these down at the same time for at least 10 seconds. If the Apple logo appears on the screen, the reset worked. If nothing happens, plug your iPhone in and try again after charging it for a little while.

If your iPhone still has no smile, try plugging your iPhone in with a different charger, or if the charger and the cable are two separate pieces, try with a different cable as well. Sometimes the charger breaks without you realizing it and can fail to charge your iPhone.

Another possibility is performing a full system restore on your iPhone. This is a pretty drastic measure because a system restore will delete all your information such as photos, videos, and other similar data. If you are reluctant to take this step right away – don’t worry, we at The TechKnow Space can take a look at your phone and see if we can save your information while fixing your phone.

If there isn’t anything particularly valuable on your iPhone, you can perform a system restore:

  1. Plug the iPhone's USB cable into the dock connector, but not into your computer
  2. Hold down the iPhone's Home button
  3. Now plug the other end of the USB cable into your computer
  4. This will open iTunes, put the iPhone into recovery mode, and let you completely restore the iPhone.

If your iPhone won’t turn on because of an impact or a fall or liquid damage, then you will need to bring it  into the Techknow Space to let us open it up and repair or replace anything that might be keeping the phone from turning on.  

Some of the other components that could be damaged because of the impact include:

  1. Charging Port – which blocks the charge from your charger to the phone. When this id damaged, it needs to be replaced.
  2. Main Logic Board or the Motherboard – this is the brain of all digital devices, and is typically too expensive to repair or replace

Liquid damage can usually be repaired, but it can have underlying issues that might prevent your iPhone from functioning normally. We have been saving liquid-damaged phones for 9+ years and our experience and advice is documented on our Liquid-Damage Information page: /information/liquid-damage/

If your iPhone still plays dead, bring it to one of our convenient TechKnow Space locations and let our experienced technicians do their magic for you, typically within a few hours.
