The Redmi Note 9S restarts automatically
If your Redmi Note 9S keeps restarting endlessly, please contact our local official service center or your seller for further assistance. They will help you in this regard.
However, if your smartphone restarts randomly, please refer to the following methods:
1. Ensure that your smartphone's operating system is up-to-date. Software updates often include bug fixes, security patches and improvements that can address software level issues;
2. Please check if the Schedule power on/off is enabled by going to [Settings] >> [Battery] >> [Schedule power/off];
3. Verify whether you installed third-party apps, such as theme, font, security/optimizer, battery manager or system launcher. Unlike the MIUI built-in features, these apps may not be compatible with the operating system or user interface and may cause your smartphone to restart automatically. In this case, please uninstall the above-mentioned third-party apps;
4. Check if there is a hardware issue by going to the [Phone] app and inputting *#*#6484#*#* or *#*#64663#*#* to enter the hardware detection (CIT mode);
5. If the above methods can’t resolve the issue, please back up the data, log out your Xiaomi and Google accounts, and perform a factory reset;
6. If this issue occurs after unlocking the boot loader, root or flash, please contact our local official service center or your seller for further assistance. They will help you in this regard.
We hope the above information is helpful. If the issue still occurs, we hope you could submit user feedback by going to [Settings] >> [Services & feedback], and wait for the future updates.
