Repair of
broken phone screens or touchscreens

Broken touchscreens and displays are undoubtedly the most common problems. We group them together because their causes and solutions are very similar.

These problems are usually caused by external physical damage, most commonly dropping the phone or sitting on it while it is in a back pocket. The replacement method differs between brands and models because their construction and design differ. No two different mobile devices have exactly the same repair procedure. Every model has details that must be considered. Our phone repair specialists understand these details so they can replace glass or a display as safely and affordably as possible. For some devices, including certain Samsung and iPhone models, replacing the touchscreen and display module is relatively expensive. This reflects the screen technology and the need for original parts to ensure proper operation. For many other devices from Huawei, XiaoMi, LG, Nokia, Motorola, Alcatel, ZTE, Sony, HTC and Lenovo, costs differ. Across all brands, premium phones use more expensive, higher-quality parts, so their repairs generally cost more.

Many customers worry that screen replacement will erase their personal data. Normally this procedure does not affect the chips storing customer data. However, the impact that caused the screen damage may also have damaged a storage chip. In our experience, customer data usually remains intact when a touchscreen or display is broken. Replacement begins by removing the broken part. This can be a difficult procedure, but it is easier in a professional workshop because at Tehnologichno Phone Repair we have all the necessary equipment. Broken glass often shatters into small pieces during removal; these can enter the electronics or injure inexperienced hands. The old adhesive securing the screen to the phone case must then be removed. We use a special chemical that removes adhesive without damaging other components. Only then is the new touchscreen or display installed. We use high-quality adhesive selected for the device's specification. The smartphone screen is then pressed against the case with specialist clamps applying carefully controlled pressure, securing the glass without breaking it. After the required setting time, the screen is cleaned and the working phone is ready to return to the customer.

Replacement of
phone charging connectors

Damaged charging connectors are another common phone fault. Most mobile devices need charging almost daily. Careless insertion, including when children connect a charger, can damage the phone's socket, making replacement necessary. This requires very delicate work on the circuit board, usually under a microscope with a specialist soldering iron. The phone must first be dismantled to reach the damaged parts. Unfortunately, attempts to charge through a damaged socket can also damage circuit-board tracks. We therefore advise customers to contact a repair centre at the first sign of a faulty charging connector, before the damage becomes more serious.

Cleaning of
phone microphones or earpieces

If the other person cannot hear you well or their voice sounds quiet, dirt may be blocking the openings through which sound reaches the microphone and speakers. Cleaning the phone, particularly these areas, usually resolves the problem. The harder part is dismantling it safely without damaging its components. This is especially important for phones that can only be opened through the display, where the risk of screen damage is greatest. Avoiding damage requires specialist equipment and skills. Although the cleaning itself is simple, we recommend having it done by a qualified, well-equipped mobile repair centre such as Tehnologichno.

Repair of
phone motherboards

Smartphone motherboard faults are common. They may result from external factors such as a power surge, liquid exposure, pressure or impact, or from a manufacturing defect or weak component. The wide range of possible causes leads to an equally wide range of repairs, requiring a large stock of spare parts and expensive specialist tools. Many tiny components are packed into a small area, making phone motherboard repairs extremely difficult and sometimes impossible. Nevertheless, our technicians make every effort to solve customers' problems with smartphones, tablets, navigation devices and other mobile equipment.

Liquid-damaged
smartphones

Liquid exposure is another common mobile device problem. Simply leaving a wet phone to dry is often insufficient to keep it working properly. Corrosion develops on electronic components over time and disrupts operation. Faults may appear much later, so users may not connect them with the earlier incident. A customer may report that a phone stopped working for no reason, but opening it reveals corrosion and signs of liquid damage. Only then do they remember a spill two weeks earlier, after which the phone initially kept working. That is why a phone should be brought in immediately after liquid exposure for appropriate cleaning and maintenance before more serious problems develop. Corrosion-related short circuits can destroy a phone completely. Prompt action saves money on expensive repairs and reduces the time spent without your device.

Software
problems

Software problems differ greatly between phones and depend on the operating system. Android problems require one approach and platform-specific solutions; the same applies to iOS devices. Here is a brief look at the problems and how they are resolved.

Software
problems on Android

Android devices have relatively few common software faults. One is a boot loop: the device keeps restarting without fully loading the operating system. Unfortunately, this apparent software problem often requires hardware work, chip programming or software reinstallation. We also resolve forgotten-password and Google account removal issues. We can help when a customer's phone freezes, restarts or runs slowly.

Software
problems on iOS

Software problems on iOS are relatively uncommon but can be difficult to resolve. A frequent example is a device stuck on the Apple logo. Depending on the iPhone or iPad model, this may require a software or hardware solution. We also regularly resolve software update errors, choosing the solution according to the particular error. There are too many examples to cover here.
