Common iPhone Screen Problems We Repair


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:

I dropped and cracked the screen of my iPhone 5 and was dreading having to go all day without a phone in order to get it fixed. I was recommended The TechKnow Space in Mississauga by Square One Mall and had an amazing experience! And it was done within an hour! I will definitely come back if I ever need a phone, laptop or tablet repair again. Everyone should come here!

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.

But luckily when I called The TechKnow Space they were able to fix it within ONE HOUR!!! I was so happy! The customer service was great!!! I took it into the Mississauga location and I would highly recommend this fast and affordable company for any repair!!! The work is EXCELLENT!!

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 6 Plus Screen Repair


According to Apple some iPhone 6 Plus model iPhones may experience problems after being dropped or knocked that may appear to be a screen problem:

Such issues include:

  • Screen flickering
  • Multi-Touch not working correctly
  • Touch screen working intermittently

A screen replacement will not fix the so-called Touch-Disease that affects the sensitivity of the touchscreen on the iPhone 6 Plus (and other models as some users have reported) either suddenly, or after one or more drops or other stressfull occurrences.  The problem does not affect components of the screen-assembly but the mainboard of the iPhone itself. Independant organizations have alleged that it is a design flaw which is disputed by Apple.

iPhone 6 Screen Repair


The iPhone 6 screen has tremendous accuracy of colour. The brightness on the iPhone 6 screen has improved brightness and clarity making it easier for outside viewing.  Further the screen is not reflective thus it is easy to see even in sunlight.

On some iPhone 6 models, the screen appears to suffer a spontaneous failure dubbed Red screen. In these scenarios the iphone screen may flash red momentarily before the iPhone restarts itself.  This may not be a screen issue, but a software or even mainboard problem.  Bring your iPhone 6 in for diagnosis and we will determine the needed red screen solution.

iPhone SE Screen Repair


On the iPhone SE Apple has focused more attention the quality of the screen than on resolution and pixel density. The Retina display allows for optimum sharpness when viewing the screen at certain common distances. 3D touch has not yet been intorduced on the this model's screen and many users (in comparisons) have reported a preference for the older technology as it has a more fluid interaction -- especially when working with photos and videos. 

iPhone SE screen flickering issues:

There have been instances of flickering lcd screen problems on the iPhone SE without having broken the screen or the glass.  In many cases the iPhone may have taken an impact (like a drop or a bump or knock) that has indeed damaged the LCD screen which would require screen replacement (even though there is no obvious physical damage to the iPhone SE screen or glass).  In some cases the screen-component istelf is not failing nor repsonsible for the problem -- it may be internal component damage (perhaps the display controller on the mainboard) or even just a software problem.   If we discover during the replacement of your iPhone SE screen that the news screen is continuing to have the same problem, we will need to do a diagnosis (which will take longer) to determine the root of the cause.

iPhone 5, 5S & 5C Screen Repair


The iPhone 5 series introduced a more vivid color gamut - for example - yellows displayed on the iPhone 5 series screens look more naturally yellow and fully saturated.  

Some users of iPhone5 series phones have reported unusual 'defective' seeming problems with their iPhone 5 screen sometimes immediately after purchase or even sometime later.  The screen may appear to have a greasy film under the glass when held at a certain angle, or even randomly occurring horizontal lines across the screen - obscuring and even blurring the image.   

When you bring your iPhone 5, (or 5s or 5C) in with these problems - we may need to perform a diagnosis of your screen problem to determine wheter the fix will be a screen replacement or perhaps another solution (such as a mainboard repair).

DIY iPhone Screen Replacement Summary


The screen of your phone is arguably both the most vulnerable and the most important part. The screens of most modern phones are primarily composed of highly engineered glass composites, which means even the smallest bump or fall can be earth “shattering” (or maybe even just screen shattering ;).

Unless you are an expert, trying to replace the digitizer/touchscreen yourself is an endeavor hazardous to your happiness. These screens are very fragile and expensive. The glass or the digitizer is fused to the display/LCD, and the display is tightly fitted to the iPhone's frame. This screen replacement is best left to experienced technicians.

Unfortunately, we have had a number of DIY-enthusiasts, victims of the many online videos, straggling into our store clutching their newly purchased screens and their iPhone looking for help.

Our experts can fix your iPhone screen in 1 hour.

 The screens of all smartphones are made of three different layers:

  • glass on top,
  • touchscreen/digitizer in the middle,
  • the LCD display underneath.

The three parts of the screens on iPhones are fused together into one component called a screen assembly, and cannot be repaired or replaced separately.

Because the screen is only one piece, you might feel it is an easy part to replace on your own. And while you could possibly be right, do you really want to risk being wrong after you have spent a few hours trying?

Let’s talk about the most popular models out there, the iPhone 6 and 6 Plus (not to mention the iPhone 6S and iPhone 7 are even more complex).

  1. Before you can even get started replacing your screen yourself, find or buy the following tools:
  2. P2 Pentalobe Screwdriver (this is a tool specifically for iPhones, don’t risk ruining the screws with the wrong tools!)
  3. Special suction cup tool, like iFixit.com’s iSlack or a high quality suction cup to help you open the iPhone up
  4. Plastic Opening Tools (these are meant to safely lift up connectors without accidentally shorting out your iPhone)
  5. Tweezers
  6. Phillips #00 Screwdriver
  7. Find a compatible replacement screen (there are lots of disreputable sources on the Internet, and very few good returns policies. How can you be sure you are getting quality spare parts?).
  8. Wait for a couple of weeks for the part to come in. Don’t mind the fact that you have an unusable phone for the time being.
  9. Once the screen comes in, you carefully open the package to ensure it wasn’t damaged in transit. Phew.
  10. Time to free up some space on your desk and get your tools ready.
  11. Remove the small screws from the bottom of the iPhone (you will need the first special screwdriver for these).

(Screw count: 2)

  1. Carefully open up the front of your iPhone, without damaging the cables which connect it to the rest of the iPhone (there is very little slack in these cables – be very cautious!)
  2. Remove the 2 screws holding the shield that covers the battery. Remove the shield and disconnect the battery. Make sure you don’t lose any of the screws or mix them up. Oh, how can you mix up 2 screws, you say? Just wait, there are plenty more to come.

(Screw count: 4)

  1. Unscrew the 5 screws holding the small metal panel in front of the cables for the screen and home button (And these screws are different lengths too – don’t mix them up either!)

(Screw count: 9)

  1. Disconnect the 4 cables from the motherboard. The connectors are very fragile, so be careful there. If you do happen to damage one – let’s just say you’ll now need to order more parts, a sophisticated soldering station and go take some courses on board level soldering. Or buy a new phone.
  2. Remove the 2 screws holding the home button bracket and detach the home button. Just to let you know, because of the Touch ID built into the home button, it is the only home button in the world that would work with your phone. So God forbid you damage it.

(Screw count: 11)

  1. Remove the 8 screws holding the back plate and remove the back plate while carefully prying off a glued cable underneath.

(Screw count: 19)

  1. Remove the screws holding the earpiece, remove the bracket and the earpiece and keep them aside along with everything else.

(Screw count: 21)

  1. Remove the cable assembly that holds the microphone, front camera, proximity sensor and the ambient light sensor. Do I even need to mention that the cable is very fragile?
  2. Now you are ready to repeat all of these steps in reverse order and assemble your phone with a new screen. Should be simple enough, eh? Just please make sure that you don’t mix up any of the screws, I just can’t stress this enough.

OK, now that the phone is reassembled, but the screen isn’t displaying anything? Or the touchscreen doesn’t respond? Well, you can try checking if there’s a loose connection somewhere… But more likely you just received a defective screen. No biggie, just go through the entire replacement process again to uninstall the screen, pay for shipping it back to the seller and hope he will send you a free replacement. You are a determined one, aren’t you?

Another possibility - you try to boot the phone up it gives you a brief blue or red screen before restarting all over again. Good job, you probably did mix up the screws and have now damaged the motherboard of your iPhone. It is now a paperweight.

The iPhone actually booted up and seems to work fine? Except that now you notice that the screen had been obviously refurbished and has visible discoloration spots? Now you’ll have to choose whether to just suck it up and live with the problems or go through uninstalling the screen and sending it back to the supplier. We already covered how straightforward that process is. Ugh.

Make a test call just in case and make sure that the proximity sensor (the thing that makes your LCD go blank when you put the phone against your ear when on a call). If it stopped working – disassemble your phone again and try readjusting it. You might need to tinker around a few times before you get it right. At least next time you do an iPhone Screen Replacement it’ll be a breeze.

There’s another option I have briefly mentioned before.

Take your iPhone to the TechKnow Space for a screen replacement! They have been replacing iPhone screens since the first iPhone launched in 2007, and have yet to encounter a broken or cracked screen replacement challenge they have not tamed!
