Reset phone
What a reset does
Resetting your phone erases all data and brings it back to out-of-the-box condition. This data will be erased
from the phone:
•
Accounts
•
Media (music, photos, videos)
•
System settings and data
•
App settings and data (including text messages)
•
Downloaded apps
Before you reset
1.
Back up your data.
If your phone works and you can unlock it:
•
If you aren't automatically saving your photos and videos to your cloud, back them up now or copy
them to a computer.
•
Make sure that any changes you made to contacts or calendar are synced to an account.
2.
Make sure you have your security information:
•
The username for a Lenovo ID account on your phone. (Settings > Passwords & accounts)
•
The password for that account.
•
If you set a screen lock, make sure you know the PIN, pattern, or password.
To restore your data after resetting, you'll need to enter security information. This shows that you or
someone you trust did the reset and helps prevent others from using your phone without permission.
