I can't make calls, why?
I need help with my phone (Xperia Aqua M4) because I can't hear anyone I call since almost 2 months now (I have this phone since August 2015). I can listening music if I use my earphones and the speakers works for make calls. But the primary function of my phone doesn't work. I tried to clean the orifices with alcohol 70% and a Q-tip. I found a lot of dirts (I work as a gardener, so). But that was not effective.
Thank you for your help,
