Why doesn't the small green light of the information prompt light on Samsung mobile phone flash?

First, reset the indicator light, then check the software problems, and finally check whether there is anything wrong with the phone hardware.

1. After the indicator light is set, press and hold the right power button for 8- 10 seconds to restart the boot attempt;

2. While restarting the phone, press and hold the menu button in the lower left corner to enter the safe mode of the phone, and then check whether it can be turned on normally. If it fails, please back up the data (contacts/multimedia files, etc.). ) and restore the factory settings of the mobile phone;

3. If the problem still exists, you can take the three-guarantee certificate of the mobile phone and send it to the nearest Samsung service center for performance testing.
