1. To begin with, press the 電源開/關按鈕 在 S7 上並等待三星徽標出現在屏幕上。

To enter Recovery Mode when Samsung Galaxy S7 doesn’t turn on, follow the instructions given below:

The power, home, and volume-up buttons must be pressed together and held for about 5-7 seconds, as in the picture below.

Once the Samsung logo appears on the screen, leave the power button only.
