The Poco X6 Pro uses an AMOLED display, which is prone to burn-in after years of use. Dial *#*#6484#*#* -> Tap "Display" -> Then "Red," "Green," "Blue." Look for any ghost images (like the TikTok + icon or keyboard) on the solid color background.
Instead of memorizing *#*#6484#*#*, you can also access the same menu via:
Settings > About Phone > Detailed Info & Specs > Tap “Kernel Version” 5 times fast.
This launches the CIT (Customer Interface Test) menu—identical to the code. Use it to check:
These codes work, but they can erase data or change system behavior.
| Code | Function | Risk Level |
|------|----------|-------------|
| *#*#7780#*#* | Factory Reset (Keep media) | 🔴 Resets all settings and removes Google accounts. Photos remain. |
| *2767*3855# | Full Factory Reset | 🔴🔴 Wipes everything—apps, media, accounts. Phone returns to out-of-box state. |
| *#*#372733#*#* | USB OTG Diagnostic | 🟡 Tests external storage connectivity. |
| *#*#6485#*#* | Battery Info | 🟢 Shows charge cycles, temperature, and real capacity (mAh). |
Note: The full wipe code (*2767*3855#) may not work on all regions due to Xiaomi’s anti-theft protections. Do not test it unless you have a backup.
