Use this guide to replace the screen for your Xiaomi Redmi Note 9T.
Replacing the screen in the Xiaomi Redmi Note 9T requires you to remove the battery. Do not reuse the battery if it has been deformed or damaged, as doing so is a potential safety hazard. Replace it with a new battery.
For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
