Repair services for the Xiaomi 12S Ultra phone
Screen and glass replacement
The Xiaomi 12S Ultra features a 6.73″ LTPO AMOLED screen (3200 × 1440 px), protected by Gorilla Glass Victus. Common damages include cracks, scratches, or abrasions in the screen glass. If the LCD matrix functions properly (no color lines, spots, or flickering), we replace only the curved glass covering the screen. In more complex cases (issues with motion sensors or in-display fingerprint faults), we replace the entire module.Battery replacement
The original Xiaomi 12S Ultra battery is a 4860 mAh lithium-ion module with 67 W wired and 50 W wireless charging. Over time, the most common issues arise as follows:Loss of capacity (the phone discharges quickly)
Battery swelling (the shape of the casing changes, risking the screen peeling off)
Slow charging or overheating (due to internal circuit oxidation)
We replace the old module with a new one fully compatible with the phone’s operating system within 1–2 hours, and check the functionality of the fast charging feature. If needed, we provide a replacement phone for the entire repair duration.
Charging port (USB-C) and flex cable replacement
Incorrect cable insertion or removal can wear out or break the USB-C contacts, leaving the phone unable to charge or sync data. We replace the damaged flex or the entire port with a new module.Volume and power button replacement
Common issues include stuck or unresponsive buttons due to dust and moisture. We restore the mechanics or replace the entire button module.Camera module repair and replacement
The Xiaomi 12S Ultra uses a 50 MP Sony IMX989 main sensor with a large format focal lens (1 inch) and optical image stabilization (OIS). Common failures include blurry images due to a broken OIS block, moisture entering behind the lens glass, and focusing module failures. We replace the entire module or, if necessary, only the lens glass.
