Use this guide to replace a cracked or broken screen on your Xiaomi Poco F3.
If the frame is deformed, it's important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure.
If your battery is swollen, take appropriate precautions. Before disassembling your device, discharge the battery below 25%. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
Note: This guide instructs you to replace only the screen while leaving the original frame and motherboard in place. However, some replacement screens come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide.
You'll need replacement adhesive in order to complete this repair.
