12.22 Why is the touchscreen slow or unresponsive during
normal use?
1.
Check whether there is a screen protective film attached. Some screen protective films
affect the touchscreen function when they are badly scratched.
2.
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.
Close the background apps that you do not need: go to
Settings
, touch
Manage apps
and
select the apps that you wish to close. Then touch
Force stop
and close the app
according to the onscreen instructions.
