I'm busy at the moment and don't have a lot of time to document all the issues I'm experiencing with 5.4, but I did notice that after the upgrade from 5.3 which was working with the complaints previously posted in another thread, now my phone doesn't ring at all. It doesn't ring or vibrate, but the screen lights up and shows an incoming call. This is HORRIBLE. I am assuming that for some reason I have this problem and no one else does, cause I can't even find anyone else complaining about it. I ran the fix permissions script, but I have no idea what could cause none of the ringtones to make a sound, and also the phone not to vibrate during an incoming call. The phone does vibrate when the call is missed, but makes no notification sound. Yes I checked all the volume levels, they are on max... A issue I kept having with 5.3 that hadn't been documented yet, and still occurs with 5.4 is when I use navigation while playing music, the navigation volume is so low its inaudible, even when turned up all the way. Something changed in 5.4 seems to have broke notification and ring volume as well.... I am going to revert to 5.3 until I get some kind of response here. Though it seems like all of these issues should be easy to fix?
