When I turn on my Huawei G2100 mobile phone, I can't do anything because there is nothing on the screen. What can I do?
Since it's a phone with limited OS capability, you will need to take advantage of your warranty (in case it exists) or take your phone to a phone service because there is no way you can diagnose its symptoms without a hardware box.
check ur battery.put paper bt battery edge
