To improve performance, some Android devices force apps to stop when your device screen turns off. This often causes apps to lose the Accessibility permission.
In this case, you need to manually re-enable the permission to maintain full app functionality. To re-enable the Accessibility permission, open your device settings, search for Accessibility
, then grant this permission to your Avast Android app.
We recommend changing your device settings to prevent the app from losing the permission. Follow the relevant steps below according to your device:

- Tap Power management, then tap Auto-start Manager.
- On the Downloaded tab, tap Deny next to your Avast app to change this setting to Allow.
