17 October 2026iTunes not recognising iPhone: computer will not connectIf iTunes or Finder does not see your iPhone, unlock the iPhone and accept the “Trust This Computer?” prompt first. Try another cable and USB port and restart both devices. On a Mac the iPhone appears in Finder; on Windows in iTunes or the Apple Devices app; update the software.
17 October 2026Samsung frame replacement: what sets the price?The mid-frame is the metal skeleton of your Samsung. It is replaced if the phone is bent, a corner is crushed or a button slot is broken. On many models the screen comes glued to the frame, so the frame may be replaced together with the screen. The price depends on the model and whether the part includes the screen.
17 October 2026iPhone touch test: 7 checks after a screen replacementiPhone has no hidden touch test menu, but a few simple checks let you test the screen easily. When you collect the device after a screen replacement, dragging an icon, drawing in Notes and testing the keyboard edges show that touch works everywhere.
17 October 2026iPhone touch screen sensitivity settings: which options exist?iPhone has no single “sensitivity” slider, but several settings change how a touch is detected. Haptic Touch duration, 3D Touch sensitivity on older models and Touch Accommodations are the main ones. A thick screen protector also lowers sensitivity.
16 October 2026Choosing a tablet repair shop: what to look forWhen choosing a tablet repair shop, look at how the process works before the price: how the fault is diagnosed, whether your approval is asked, which part is fitted and whether the part is invoiced. Below are the questions you can ask before handing over your tablet, and a short look at our own process.
16 October 2026How to become a phone repair technicianTo become a phone repair technician you need basic electronics, careful disassembly skills, battery and static safety and the ability to use measuring tools. Vocational schools, courses and working alongside an experienced technician are common routes. Opening your own shop needs a licence and tax registration.
16 October 2026Is a cracked front glass covered by warranty?Front glass cracked by a drop or knock counts as accidental damage and is outside the standard manufacturer warranty. A crack that appears by itself with no impact mark may be treated as a manufacturing fault; the maker decides. If you have AppleCare+ or insurance covering the screen, check its terms.
16 October 2026How to tell if a phone’s screen has been replaced: buying second-handYou can tell whether a second-hand phone’s screen has been replaced from a few signs: a gap or excess adhesive at the edge, tool marks on screws, dust around the front camera and colours that differ from the same model. On iPhone, Parts and Service History can show it too. A good replacement may leave no trace.
16 October 2026Why does the iPhone audio IC fail? Symptoms and repairOn an iPhone, the audio IC is the chip that manages speaker, microphone and headphone sound. A drop, the phone bending or liquid contact can damage this chip or its solder joints. The most typical sign is a greyed-out speaker button during calls and voice recording not working. The repair is done on the board.
16 October 2026Screen replacement in front of you: what you can watch and what to askA screen replacement in front of you means your phone is repaired where you can see it, not in a back room; you see the old screen removed and the new part fitted. At Cep Market’s Kadıköy store, repairs are done in front of the customer. Still, what matters most is the part type, the invoice and testing together.
16 October 2026OPPO A5s stuck on the logo or crashed after a theme: what to do?On the OPPO A5s, an incompatible theme or an interrupted update can crash the interface: touch stops working, the navigation keys and notification panel disappear, or the phone stays on the logo. Force restart and try safe mode first; if that fails, recovery mode. Wiping data erases everything.
16 October 2026Can you put a swollen battery in the freezer? Why not, and what to doDo not put a swollen battery in the freezer. Cooling does not reverse swelling, and moisture condenses inside a phone taken out of the cold, raising short-circuit risk. Unplug the phone, switch it off, put it on a non-flammable surface and get the battery replaced. If there is smoke, move away and call 112.
16 October 2026How to tell if a phone screen is aftermarket: tests you can do at homeA few tests tell you, to a large extent, whether the fitted screen is aftermarket. On iPhone, Parts and Service History shows the screen’s status. On a phone with an OLED screen, if a black screen glows faintly in a dark room, an LCD part may have been fitted. The fingerprint reader and colours also give clues.
16 October 2026Toothpaste on cracked phone glass: does it work, and what if you already used it?Putting toothpaste on cracked phone glass does not repair the crack; it may seem to hide fine scratches for a while, but it does not last. If you already used it, check whether paste got into the speaker, microphone or charging port, and wipe with a dry, soft cloth. The fix is a glass or screen replacement.

16 October 2026iPhone 13 Pro and 13 Pro Max screen replacement: mind ProMotionThe iPhone 13 Pro has a 6.1-inch screen and the 13 Pro Max a 6.7-inch one; the two do not share a part. Both have ProMotion, refreshing up to 120 times a second; on compatible parts this support can vary by part. The options and differences are explained before approval; test scrolling at collection.
16 October 2026Cleaning an iPhone charging port: care by port type and preventionAn iPhone charging port can be Lightning or USB-C, and the difference matters when cleaning: a USB-C port has a thin tongue in the middle that poking can damage. Most lint comes from pockets; checking the port with a light now and then and not charging in damp places prevents trouble without cleaning.

16 October 2026How long does an iPhone logic board repair take? Preparing to be without your phoneHow long an iPhone logic board repair takes depends on the fault, part availability and testing; the exact time is given after the free diagnosis. As the repair may take a while, prepare before leaving the phone: back up, put your SIM card in a spare phone and plan where you will receive two-step verification codes.
16 October 2026How much is a Samsung touch screen repair? Why the screen is usually replacedOn most Samsung models the touch layer is built into the screen, so a touch fault usually means a screen replacement and the price is set by the screen type. AMOLED, curved or foldable screens are priced differently. Rule out the protector and software first; you can get a price by sending your model number.
