| Symptoms. | Probable cause | Decision |
|---|---|---|
| The screen is lighted but does not respond to touch. | Damage to the touchscreen plume | Disassembly and replacement of the plume (sweeping station is required) |
| Partially operating (one zone) | Mechanical damage to the digitizer | Replacement of touch glass |

💡
If the phone falls into water, DO NOT try to turn it on. Place the device in a silica gel bag for 48 hours. Turning on the wet phone shorts out and causes permanent damage to the motherboard.
4. Charging problems: not charging or discharged quickly
Fast discharge or no charge is always a complex problem.
- 🔌 Cable and power supply (try the original kit)
- 🔋 Charging ports (check for contamination)
- 📱 Battery state in Settings → Battery
If Xiaomi phone doesn’t charge at all:
- Clean the charging port with a wooden toothpick (not metal objects!)
- Try charging from another Quick Charge-enabled device
- Check if the overheating protection is working (the phone can block charging at temperatures above 45).°C)
For battery diagnostics:
- Enter the number #4636##
- Go to Battery Information
