Phone Repair FAQ

Screen Issues

There are very few phones being manufactured today with the glass touchscreen as a separate component. Therefore most phones require the replacement of the entire screen assembly as one part. See a list of all phone models with screen, glass & LCD replacement pricing.

When your phone seems to be working (i.e. it's ringing etc.) but the display stays off the most probable cause is LCD failure requiring screen or LCD replacement.  In some very rare cases the display controller circuits on the logic board could be damaged instead or even as well.

There are a few known cases of touch response issues due to motherboard failure however the vast majority of touchscreen problems require the screen to be replaced.

Your phone has a component behind the screen called a proximity sensor. This sensor detects when you hold the phone to your ear and turns off the display and touchscreen preventing functions from being activated by your cheek.

This sensor rarely fails on its own -- it can easily be damaged if the glass covering it is shattered.

If your device has sustained damage during drops and impact, sometimes the frame or housing of the device becomes warped or bent.

This can create a problem when installing a new screen - as the mounting points may not align, or the frame is bent inward impeding where the new screen needs to be.

Fortunately in most cases we are able to straighten and/or repair the frame and proceed to install your new screen.

Power & Charging

Panic! Your phone won't turn on. What now?

It's diagnostics time.  We will perform a thorough inspection and determine where the fault lies.  

No power problems could include the following possible causes:

Behaviours that may be related to a battery problem could include:

  • Phone turns off suddenly
  • Running slow
  • Laggy touch response
  • Won't fully charge
  • Battery swelling
  • Screen has broken (seemingly on its own) from internal pressure

If your charger won't plug in it's pretty obvious that there is physical damage and the port needs to be replaced. wink

... But damage to the charging is port is not always readily visible. 

Symptoms of charging port damage or failure may include:

  • Loose connecter - charger doesn't firmly plug in
  • Charging stops or is intermittent
  • Does not detect when a charger is plugged in
  • Does not detect on a computer

Camera Problems

Whats going on when lining up for a nice shot and the image is always blurry or the view is constantly shaking?

These are some possible causes

  • Scratches on the external camera lens
  • Scratches on the inside camera lens
  • Damaged or broken focus

Blurry or out of focus images can be a result of a dirty or scratched lens, either the external protective lens or the internal camera lens itself. If cleaning the lens doesn't resolve the issue then either the camera or the lens needs to be changed

If the image is shaky or appears to be vibrating then the focus mechanism within the camera is damaged and can be fixed by replacing the camera.

In some cases you might see dark spots in the image while trying to take a picture and also appear in the final image. These are likely caused by a scratch to the internal lens and can be fixed by replacing the camera component. 

Typically, this occurs when the external lens has become damaged, exposing the internal camera mechanism which has become scratched. Other times, this can happen from liquid or dust particles getting inside the camera.

Let us change your camera or lens so you can go back to taking awesome photos.

Audio Problems

Having already tried another pair of earphones wink you've still got no sound.

Here's what could be wrong:

  • Damaged connectors inside the audio jack
  • Damaged audio jack mainboard connector (especially if the phone has been opened)
  • Water or other liquid inside the jack

Most phone audio jacks (headphone jacks) are replaceable as a component and we stock jacks for most common phone models.


"Are you there?"

You answer your phone but it seems no one can hear what your saying.  

The microphone has failed. Most phone mics can be replaced within 1 hour.

When you answer the phone and it seems like there's no one there - you can't hear anything - you quickly switch to speakerphone and all's well you probably have an earpiece (receiver speaker) failure.

Most phone earpiece speakers can be replaced within 1 hour.

The speakerphone function usually relies on the loud-speaker to produce sound -- the same speaker that plays music, notification sounds and ringtones.

If the functions above aren't working you will need your loudspeaker replaced.

Signals and Antennas

Only after a thorough diagnostics will our technicians be able to determine if the antenna is a cause of your WiFi woes.

WiFi problems could be caused by software issues, a failed WiFi transceiver, the antenna, or even logic board damage.

Bluetooth connection issues could be a result of:

  • Impact - affecting the logic board
  • Heat problems
  • Antenna connections
  • Software

We will diagnose your bluetooth connectivity problems and advise accordingly. 

There are many possible casues of a loss of carrier signal - meaning no voice calls & no data connection.

Possible causes include:

Our technicians will perform diagnostics and determine the cause of the connection loss and advise the you of the necessary solution.

What does it mean when a phone is blacklisted?

A phone's IMEI may be blocked by the original issuing carrier for any number of reasons - for example having been reported stolen.

This means that your device will not be able to work with any North American carrier network.  

How to check if a phone is blacklisted.

Buttons & Housing

Sometimes the physical button itself has worn or broken and requires replacement. We stock buttons for most common models of phones. 

In other cases the switch underneath the button is the problem - which we also repair.

Housing replacement on many phones is intricate -- requiring complete dissassembly.

Back covers can be replaced on most phones within 30 minutes.

We stock housings, and back covers for most popular phones.

Logic Board Repairs

Logic board replacement for phones can often be as expensive (or more) than replacing the entire device. 

We do however do logic board repairs.

A Motherboard or main-board or logic board is the Central Nervous System or the Brain of a devices.

All components on a device, be it the screen, charging port, microphone or any other component on the device has a corresponding software or functional counterpart on the logic board that communicates with the component.

When the function, say for the microphone, gets damaged on the logic board there is no way for a microphone to work unless the logic board is replaced, or the functional software capability for the microphone on the logic board is repaired.

Replacing a logic board is rarely cost-effective. New logic boards can only be sourced from the manufacturers who will not typically supply these to repair shops. Also, since your data and apps reside on the flash memory on the logic boards, all your data is lost when you replace the logic board.

Logic boards can however be more cost-effectively repaired. There is a 50% success  rate with repairing logic boards. This has the advantage of having all your data and apps available for you to use. smile

Damaged SIM trays can often be repaired. On some phones it is a separate component and can more cost-effectively be replaced on its own.  

More often than electronic failure - the connector pins which contact the SIM card get bent or broken off from inserting an object into the slot, or even inserting the SIM backward.

We repair and replace damaged SIM reader trays typically within 1 to 2 hours.

Saving Data

Depending on the nature and extent of the damage your data may be able to be saved.

For example your phone's LCD has failed but it's an old model and a screen replacement is more expensive than buying another phone. In ths case we can extract your phone's data to external storage media such as a flash drive or onto another phone.

General Repairs

The diagnostics process varies by device and problem.

Typical Repair & Diagnostics Turnaround Times

Most of our repairs are completed the same day and in as little as 1 hour or less!

Typical Repair & Diagnostics Turnaround Times

Although we do prefer that you keep you receipt and present it for any warranty related or follow-up issues, we do log each and every repair performed.

If you have lost your receipt and require follow-up services, we are able to search for your record(s) using information you have provided to us when you completed your customer profile in-store.

We provide a printed Work Order ticket to all customers upon booking in devices for service.

It is very important that you retain your Work Order ticket and present it upon pickup to help ensure the secure return of your device to its rightful owner.

Lost or destroyed Work Order tickets:

For alternative identification methods see Device Pick-up for details before coming in.

Essentially - everything can be repaired, it is typically a matter of cost.

Some parts (smartphone mainboards for example) are expensive compared to other components and such repairs may even exceed the cost of replacing the device. 

After diagnosing the cause of the problem we will provide a repair estimate and proceed upon your approval.

If you decide not to proceed with the repair(s) our Diagnostics Fee will apply.

If a seemingly obvious problem turns out to caused by a different component or if there is additional damage discovered during the repair process we will provide you a repair estimate and proceed upon your approval.

If you decline the repair estimate our Diagnostics Fee will apply.

We do comprehensive liquid-damage cleaning, corrosion removal & repair for devices that have had water or other liquid exposure.

Please read the Water Damaged Device Repair page before bringing your device in for repair.

"Should I repair my device or buy a new/used one?"

It's usually the first question that pops into our heads when we consider paying for a repair.

Repair vs Replace

We commonly accept mail-in and ship-in repairs from both individuals and companies.

Please follow our Mail-In Repair Instructions 

Logic board repairs are considered when all other repair options have been exhausted.

We understand the motivation to get your damaged device working again as soon as possible.  

We know that some people will undertake a Do-It-Yourself repair attempt or turn to friends and family who may have some technical knowledge.

In other cases some may have sought a less expensive seeming repair at a discount shop who was ultimately unable to successfully complete the repair.

Many times customers bring their devices to us after one of these failed alternative repair attempts.

Our policy and procedure for devices that have been opened or partially repaired


We carry mobile device parts in stock for common (and less common) repairs including:

  • Screens
  • Charging Ports
  • Batteries
  • Speakers
  • Buttons

If your device repair requires a part that we are out of stock on or do not carry we may be able to special order it.

Special Order Repairs

We generally discourage bringing your own parts for a number of reasons.

In exceptional circumstances we may agree to perform the repair at our discretion.

See Why Risk Bringing Your Own Parts.

We do not sell internal batteries, screens or any other internal parts over the counter, unless we determine it (at our discretion) to be an exceptional final-sale circumstance.

Buying Parts vs Buying a Solution.

Data Security

We need the password locking your computer, laptop or cell phone because we want to provide all our customers with the best service quality they expect of us.

You wouldn’t expect a mechanic to work on your car without opening up the hood or looking under the carriage. Your password is required for our technicians to make sure the repairs are done correctly and efficiently.

Your password allows us to test all the functions on your device both before and after the repair.

Password Policy

We take every effort to ensure the integrity of the data on your device.  Most common repairs often involving component replacement do not affect the stored data whatsoever.  

In some situations the damage to the device which prompted your visit to a repair shop would have already caused your data to be lost.  We do offer data recovery services for these scenarios.

Other situations involving reinstalling operating systems or firmware, or when the device does not turn on or fully start, may require wiping the device data.
