12.21 What can I do if I forget the screen unlock pattern or
password?
When you set the screen unlock pattern, set a backup numeric password according to the
onscreen instructions. When you forget the screen unlock pattern, you can use the backup
numeric password to unlock the screen.
If you forget the backup unlock password, you can update your phone.
Updating your phone erases all user data from your phone.

12.22 Why is the touchscreen slow or unresponsive during
normal use?
Check whether there is a screen protective film attached. Some screen protective films affect
the touchscreen function when they are badly scratched.
Opening a large app or lots of background apps may temporarily cause the phone to freeze,
making the touchscreen unresponsive.
Wait patiently or clean up background apps and then check whether the touchscreen has
returned to normal.
