Display issues: flickering screen, color calibration problems, features like Dark mode or Adaptive
brightness aren't working correctly
•
Sluggish phone performance
•
Incorrect calculation of available storage space
•
Issues installing or updating an app
If you’re unsure about the source of your issue, use this reset to see if it resolves the issue. This won't affect
your data, apps, or personal settings. It's less drastic than a full factory reset, which erases everything.
What gets deleted/removed when you reset
•
Changes you made in Settings > Battery, Display, or Storage
•
App-specific battery optimizations (After you reset, the phone will relearn your charging patterns and
app usage, potentially improving battery life over time.)
•
Unnecessary cache data and any corrupted system files
Your personal data, like photos contacts, and apps, will not be deleted. The reset only affects the system's
management of those areas.
Reset
1.
Go to Settings > System > Reset options.
2.
Tap Reset device settings and unlock the phone.
3.
To confirm you want to reset, tap Reset device settings again.
Reset app preferences
This reset doesn't allow you to choose individual apps; all apps will be reset.
Before resetting all apps, if you're having trouble with one or two apps, reset the apps individually.
If you still experience the following issues, then reset all apps:
•
App crashes frequently or won't open
•
App doesn't behave as expected
•
App uses too much battery or data
•
App sends error messages or notifications
•
App causes phone to be slow or unresponsive
What gets deleted/removed when you reset
•
Selections you made for default apps to use for specific functions or to open specific file types; you’ll be
asked to choose again.
•
Apps you disabled manually to prevent them from showing in the app tray or on the home screen will
reappear; you can disable them again.
•
Preferences you set for app notifications, like hiding notification content from the lock screen; you can
reset these.
•
Changes in background data and app permissions.
