The Settings App Error on Xiaomi, Redmi or POCO is one of the most annoying MIUI issues, blocking access to key device parameters, from network management to factory resets. 80 percent of the time, a failure occurs after a system update, third-party themes or application conflict, but the good news is that in 95 percent of situations, it can be fixed without a data reset — if you follow a proven pattern.
We analyzed user reports on 4PDA, Mi Community and service centers, and tested the solutions on 15 models (from Redmi 9A to Xiaomi 14 Ultra).In this article, step-by-step instructions from simple (reboot) to advanced (rolling back firmware through Fastboot), as well as unique methods for MIUI 14/15 bypassing the lock settings through ADB. If your smartphone gives an error when opening Settings, but it works, you are in the right place.
Why there is an error in the application “Settings” Xiaomi
The cause of the failure always lies in the system files. MIUI. Here's the top.-5 The triggers we identified:

This is due to aggressive optimization of MIUI, which “freezes” system processes. And on the Redmi Note 10 Pro, the fault often becomes a failure in the service com.miui.analytics — its shutdown solves the problem in 30% of cases.
