Today my phone did a software update. Prior to the update my in call volume was fine. Post update the in call volume is so low I can barely hear it ring and to hear the person on the call I have to turn on speaker phone. My call volume is turned all the way up. I cleaned the ear piece, restarted my phone and I tried a factory reset. No luck. I'm not sure what my next course of action is. But I can say that each time my phone updates, the changes that are made with each new update make my phone worse than before. Either a feature I enjoyed is removed or changed or something such as this happens. IMO the updates are not improving my experience with my galaxy.
