Frequently Asked Questions

Will removing my Google account delete my apps and data?
No, removing and re-adding your Google account won't delete installed apps or local data. However, you may need to re-sync contacts, calendar events, and other Google services data.
Why does Android Error 491 keep coming back?
Recurring Error 491 can be caused by insufficient storage space, outdated Google Play Store version, corrupted system files, or account synchronization conflicts with multiple Google accounts.
Can I fix Error 491 without removing my Google account?
Yes, try clearing Play Store cache and data first, then restart your device. If that doesn't work, clearing Google Play Services cache may resolve the issue without account removal.
Does Error 491 affect all Android devices the same way?
