Alright well I tried out the 790 beta for a little while, a few things made me revert back to 704 and for the sake of providing some feedback, I'll try to note down all the bugs I encountered. Like I said a few things made me revert, but the last one was that when I unplugged my phone and stopped playing music, the little widget on the lock screen that shows name of song, play, skip, just stays there. It doesn't go away and I can't swipe to get rid of it. I was also having some audio issues, popping I believe. The phone I use is a ZTE blade v8 pro. I also use Next lock screen, if that's relevant at all to the issue of the widget bug.
