How to fix black screen

To fix a black screen issue on Xiaomi Mi Note 10:

1. Perform a forced restart by pressing and holding the power button for about 10-15 seconds until the device restarts.
2. If the issue persists, ensure the device has sufficient battery charge or connect it to a power source.
3. Try booting into Safe Mode by pressing and holding the power button, then long-pressing "Power off" until prompted to enter Safe Mode. If the screen works in Safe Mode, an app might be causing the issue.
4. If the problem persists, consider factory resetting the device through recovery mode. Backup your data before performing this step.
5. If none of the above solutions work, contact Xiaomi customer support or visit a service center for further assistance.
