A factory data reset may help with a blank or frozen screen, apps crashing or freezing, keypad/touchscreen problems, can't hear, device making noises, can't make or receive calls, and device won't sync.
Caution:
- If the device is responsive and can be powered on, the preferred reset method should be performed.
- For devices with Android Device Protection turned on, it's imperative Google sign-in credentials are known prior to completing a factory reset with the device powered off. If credentials are unknown do one of the following:
- Attempt to sign in with any Google™ account previously used on the device.
- Reset the password.
- Perform a factory data reset only if absolutely necessary as it removes all data including:
- Contacts
- Email accounts
- System and app data
- App settings
- Downloaded apps
- Media (Music, pictures and videos, etc.)
- Ensure the device is powered off.
- Simultaneously press and hold Home (located at the bottom) + Volume down (located on the left edge) + Power buttons (on upper-right edge) until 'Powered by Android' appears then release.
- From the Android recovery screen, select wipe data/factory reset.
Utilize the Volume buttons to highlight and the Power button to select.
- Select Yes -- delete all user data.
Allow several seconds for the factory data reset process to complete.
- Select reboot system now.
Allow several minutes for the reboot process to complete.
If applicable, set up your device.
