I've been having problems (3 trips to my Verizon store) with the general volume on my Samsung s4...call; notifications; all volume is extremely low. The man at the store told me to take the battery out, replace it- and that would reset all. This advice didn't work. The next time I took it in they cleaned it and I left with it working again...but not for long.
Help! All I can hear well is the voice mail.
I was also told the Speaker phone did not switch back to the regular ear piece after using it. DON'T USE THE SPEAKER
I shouldn't be having these problems.
