Please follow the instructions in the manual if you want to open the phone,
disassemble the accessories, and do not try other methods.
Please avoid falling, knocking, or shaking your phone. Rough handling of the phone
can cause the screen to rupture and damage the internal circuit board and its delicate
structure.
Do not use chemical solvents or detergents to clean your phone. Wipe the phone
case with a soft cotton cloth dampened with water or mild soap.
Clean the display and lens with a clean, dry, soft cloth.
If you encounter a problem while using the phone, making the screen unusable, the
method is as follows: For a mobile phone that cannot remove the battery, please
press and hold the power button for more than 12 seconds. The mobile phone will be
forced to restart. After the restart, unlock the phone. If your phone has removable
battery, then remove the battery, insert it again and boot up the phone.
When the charger is not in use, please unplug it from the power outlet. Do not
connect the battery that has been fully charged to the charger for a long time, as
overcharging will shorten the battery life.
