2 Screen and display
2.1 What can I do if I forget the screen unlock password or
pattern?
You can solve this problem by reformatting your phone. Reformatting your phone erases all
user data from your phone.
Reformatting using a microSD card:
1. Download the software package corresponding to your phone model from
http://consumer.huawei.com.
2. Copy the dload folder in the software package to a microSD card's root directory.
3. Power off your phone and insert the microSD card into your phone. Then,
simultaneously press and hold the power, volume up, and volume down buttons to enter
reformatting mode.
Your phone will be reformatted and restored to its factory settings.
If your phone can't be reformatted, contact Huawei technical support or take your phone to an
authorized Huawei service center.
2.2 What can I do if the touchscreen doesn't work?
If this happens when there is water or oil on your hand or the touchscreen:
Use a dry cloth to wipe your hand and the screen.
Press the power button consecutively twice to restart the screen to let it automatically
calibrate.
If this happens when the phone is charging through an in-car charger or non-standard
charger:
In-car or non-standard chargers may cause touchscreen failure. Use the charger that
comes with your phone for charging.
If the problem persists, contact Huawei technical support or take your phone to an authorized
Huawei service center.
