How we test our mobiles
Our testing process is rigorous and consists of at least 20 different electronic controls. For a phone to reach the grade phase, it must pass each of these tests with flying colors.
I test process we use on the camera, touch screen, microphone, speaker and all touch sensors work. We also check Bluetooth and WiFi connection, and we make sure that the SIM card has good contact with the phone's internal SIM card slot.
