Safe Mode on Xiaomi Redmi 9: How to turn on and use for diagnostics

Xiaomi Redmi 9 is one of the most popular budget smartphones, but even it is not immune to malfunctions. If your device starts to slow down, spontaneously reboot or give out application errors, the first thing to do is run it in Safe Mode, which helps to determine whether problems are caused by third-party programs or system problems.

In this article, you will find 3 working methods for enabling Safe Mode on Redmi 9 (including Redmi 9A/9C/9T models), as well as detailed instructions for exiting mode and fixing typical errors. We will break down the nuances of working with MIUI 12/13/14, explain why the smartphone may not respond to commands, and give tips for diagnosing malfunctions.

• 🔋 Battery is draining too quickly (maybe the background software is to blame).
• 🚫 Errors such as "Application stopped" or "System does not respond" appear".
