The size of the Samsung G3812's fuselage can be said to be just right, it feels completely suitable for the hand shape in the hand, the grip is very comfortable, and there is no problem with one-handed operation.

The more obvious difference between it and the Samsung Galaxy S3 on the front is the menu and back touch keys, the S3's touch keys are hidden, while the Samsung G3812 is visible.

The back of the phone is made of plastic back shell, which has a piano paint process, which is anti-slip and anti-friction. Next to the 500W rear camera, it has LED fill lights and speakers, and it is still different from the Samsung Galaxy S3 in the back layout.

The steps to enter are as follows:

1. After entering * * in the dial pad, you can directly enter the engineering debugging interface.

2. Under the test interface, you can view "mobile phone information", battery information, usage statistics and WLAN information (Wi-Fi network information).

If you notice that your phone has been losing power faster than before, but it has been turned on less often and used for more time, you may want to include it in the rogue software.
