Broken glass repair
For this model, we actually replace the entire screen assembly for you, but charge you a lower price. When your screen is recycled, we recoup the difference. We therefore install a brand new screen on your smartphone, only transplanting certain small parts from the old one, such as your front camera, proximity sensor and home button.
*Housing damage: Damage to your housing can dramatically influence the results of a front glass replacement. Generally made from aluminium, your casing can be greatly affected by physical shocks and will prevent a new glass screen from fitting properly. The glass panel cannot bend, so it will pop up or break, if the angle of the chassis or bent in corners are putting strain on it. In this case, we would need to do work on your housing or, in more extreme cases, replace it altogether.

LCD + Touch panel repair
The entire screen assembly must be replaced whenever the image or touch functions fail. The glass could be broken or intact, there might be a crack underneath the glass panel or there could be no visible signs at all. You might have a working phone with a black screen, altered colours, lines or spots on your image, or you could simply have a screen that doesn’t respond to touch properly. In all these cases, replacing the faulty screen is necessary. The new assembly is complete and comes with its own glass panel.

Battery replacement
Signs of battery trouble include poor charging, a battery that doesn’t last long or that drains abruptly (for instance jumping from 70% to 50%), your device shutting down when running demanding applications or when affected by cold, as well as physical manifestations (e.g.: swelling). On models where the battery is not user-removable, an inflated battery may push on the screen and make it slightly pop up from the middle. In all these cases, the proper course of action is to replace the battery.
There are, however, other issues which may pose as a battery problem. These commonly include liquid damage, burns, software issues and damage to the power circuit. We begin by testing a new battery with the device. If the problem persists, we proceed to diagnosing your phone, keeping your original part. However, in most of these cases, the underlying issue will have permanently damaged your battery, so changing it is required anyway.

*User-removable vs. non user-removable: Some devices allow the user to instantly access the battery, such as through a back cover that can be unclipped easily. An example would be the Samsung Galaxy S5. For an iPhone 7 however, the screen must be lifted in orded to reach the battery. Similarly, the Galaxy S6 has a back cover that requires heat, tools and skill in order to remove it.
For user-removable batteries, we only charge the price of the part and install it for you as a courtesy.
For non user-removable models, the price reflects the labour required to perform the operation. Please check your device’s corresponding repairs page in order to find out which category it belongs to.

Charging port repair
Your charging port usually fails for some rather simple reasons: dirt gets lodged in it, the small pins which connect to your charger break or become deformed, liquid damage, or the actual part becomes loose because of rips to its soldering points.
Lint can be a common nuisance if you keep your phone in your pocket, so if you suspect something is stuck in your charging port, try to clean it with a pin or similar object before bringing it in. Bad charging ports often require you to wiggle the charger before responding, don’t allow the charger to fully come in or do not respond at all. Charging port issues can sometimes turn out to be something else, notably charging circuit failure, which is an internal problem.

Liquid damage repair
It seems quite obvious that getting water on or inside your phone is a bad thing. But the reasons aren’t always as obvious. Indeed, liquid damage is one of the most destructive things that can ever happen to your device. Through its very nature, water can penetrate the tightest crevices and affect even the most hidden components. The worst damage is often where water gets trapped in a tight space and has enough time to wreak maximum havoc.
We are using “water” as a general term here, but different types of liquid will affect your device in different ways. For instance, distilled water is a poor conductor for electricity due to its lack of minerals and will cause minimal trouble, but chlorinated water and salt water are extremely dangerous for electronics. These, and other types of mineral-rich and organic-rich liquids, are what is meant by the word “water” in this article.
When water first enters your phone, it will follow whichever path it can take, depending on how the device is built. Pockets of water may form in spots that the liquid finds itself drained to, and these will be the hardest-hit areas. Short circuits will be the first problem, since water – as a great
conductor – will modify the path of electricity through the phone, connecting points on the circuits that are not supposed to connect in that order, effectively shortcutting between them. Then, chemical reactions with various components will cause oxidation and corrosion to set in.
Therefore, the damage is instant, but can also affect the device in the long term. One often sees phones working for a time after the initial spill and then stopping after hours, days or even weeks, as corrosion was able to overcome the components it was slowly eating away. Because of the unpredictable nature of water flooding your phone, a careful examination of the device’s circuitry and components is mandatory. Repairing the damage can range from a simple clean-up to tricky operations lasting days or weeks, to the outright impossible.
Unfortunately, the damage can be irreversible even when swiftly detected. A motherboard corroded to the point of not functioning can be saved by masterful circuit work, but will sometimes be beyond human intervention.
What is certain is that time significantly increases the chances of encountering irreversible damage. This is why it’s important to bring your device to us as soon as possible if you’ve had a water spill, or worse, if your phone has been submerged in some liquid. There are no guarantees, and there can never be when it comes to water damage, but you are at least maximizing your chances. We advise against attempting
to attack the problem yourself – especially through home remedies such as rice – as any significant effort against this type of damage requires opening the phone up. Drying the phone from outside only accelerates the drying process, leaving minerals and organic matter trapped inside. However, some steps should be taken, immediately to start off the process on the right foot. If your phone is on, attempt to turn it off. If it is off, do not turn it back on, and do not charge it. If your battery is easily removed, take it out.
At iTronics, we’ve seen hundreds of devices affected by water, and our success rate with them is around the 65% mark. It is one of the most difficult repairs one can get, and the unpredictability of these cases is hard to imagine. Minor water spills have killed phones, while devices that had been completely submerged have been saved. Always a new challenge, water damage is not to be taken lightly, but making the right choices can save you a phone.

Ear speaker
Your ear speaker is where the sound comes from during a regular call (phone against your ear). Therefore, the best way to test it is during a call: if you are having trouble hearing the person at the other end of the line, you might have a faulty ear speaker. Just like the loudspeaker, this part can be affected by water damage, physical damage and foreign particles, as well as software bugs. On some models, lint or dirt will make it hard to hear properly during a call.
In some situations, sound problems during a call might have nothing to do with the ear speaker. If your telephone remotely connects to a bluetooth device, if it erroneously detects earphones, or for other reasons (like the call volume set to low), you will have trouble hearing through the ear speaker.

If you see dirt inside your headphone connector, you may attempt to gently remove it using a pin. However, if the problem is caused by an object, such as a broken jack, the device will likely require professional attention. In case of invisible damage to your connector, or if you are simply not sure what’s wrong, we invite you to bring us your device before attempting anything.
