Xiaomi and Redmi Common Problems - Fix Guide

Xiaomi shows ads in system apps by default. Here's how to disable them completely:

1. 1Disable MSA (MIUI System Ads): Settings > Passwords & Security > Authorisation & Revocation > find "msa" > toggle OFF. Wait 10 seconds if it fails, then try again.
2. 2File Manager: Open File Manager > three-dot menu > Settings > turn OFF "Recommendations"
3. 3Security app: Open Security > Settings cog > turn OFF "Receive recommendations"
4. 4Mi Browser: Open Mi Browser > Profile > Settings > turn OFF all recommendation toggles
5. 5Music app: Open Music > Settings > turn OFF "Recommendations"
6. 6Downloads: Open Downloads > three-dot menu > Settings > turn OFF "Recommendations"

MIUI and HyperOS aggressively kill background apps to save battery, which prevents notifications from arriving. Fix this for each important app:

1. 1Battery settings: Settings > Battery > App Battery Saver > select the app > No Restrictions
2. 2Autostart: Open Security app > Manage Apps > find the app > enable Autostart
3. 3Lock app in recents: Open the app, go to the Recents screen, pull the app card down to "lock" it (a padlock icon appears)
4. 4App notifications: Settings > Apps > select app > Notifications > ensure all channels are enabled
5. 5Repeat for WhatsApp, Gmail, Slack, and any app where you need timely notifications

1. 1Open Security app > Battery Saver
2. 2Select each important app > set to No Restrictions
3. 3Go to Settings > Battery > Battery Saver > Ultra Battery Saver — make sure this is OFF for normal use
4. 4Disable MIUI optimisation if available in Developer Options (helps with app background behaviour)

Xiaomi is transitioning from MIUI to HyperOS. Here's what changed:

• • HyperOS (Xiaomi 14+): Fewer system ads, better notification delivery, closer to stock Android behaviour. Most MIUI-specific problems are reduced.
• • MIUI 14 and older: More aggressive battery management, system ads in multiple apps, notification delays are more common.
• • Settings paths may differ: Some settings have moved in HyperOS. If you can't find a setting, use the search bar at the top of Settings.

MIUI's forced dark mode can make some apps look broken — white text on white backgrounds or unreadable content.

1. 1Go to Settings > Display > Dark Mode
2. 2Tap "Individual Apps" or "More Dark Mode Options"
3. 3Disable dark mode for specific apps that display incorrectly
4. 4If the app has its own dark mode setting, use that instead of MIUI's forced dark mode

1. 1Wait 24-48 hours after updating — the system re-optimises apps in the background
2. 2Clear system cache: Settings > Storage > Cached Data > Clear
3. 3Restart the phone after clearing cache
4. 4Disable animations: Developer Options > set animation scales to 0.5x
5. 5If still slow after 48 hours, consider a factory reset as a fresh start
