Jiayu F1 - automatic volume down, change the ROM does not help
From the month was using without problems F1. The day before yesterday, I noticed that touching the phone itself began to silence the - appeared and the volume bar slider in increments went down to complete silence. Amplification manually at the moment helps, but then again they veer slightly, down time by one step, once the end. This is done entirely in an uncoordinated manner.
I do not have any management application sounds or mute mode. Phone did not fall, he was flooded . How not to go crazy, this control works fine, mechanically nothing a malfunction or defect of the controller that has cropped vol - .
I've done 3 substitution roms, nothing helped. When one is as I hoped it would be OK, but after installing the new traps, where it was totally quiet, suddenly again wariowaniem nightmare with the volume slider back.
Could it broke something in the electronics and phone is only suitable for basketball?
I beg you, help.
Thanks in advance for any tips.
