Recently bottom speaker got really really quiet. Not completely, but sound is reduced by about 50 dB. I cannot use speakerphone (as it only uses bottom speaker which is barely hearable). I can view videos only in mono (as they use both speakers and top one works perfectly). Any ideas? I tried safe mode - same thing. I tried service tests - it cannot start, in fact it crashes my dialer. Also after some time "link sharing" stops working, don't know if that is related to the problem.
