Okay, so the long awaited up-rev to Jelly Bean has come and gone. And as we all knew would be the case there are growing pains associated with this. For me there has not been any increase in performance and in fact it seems to be a little slower and laggier, although not much. But there are other little things that are more annoying. The biggest issue for me at this point is that my Bluetooth connection seems to constantly lose connection to my Bose SoundLink speaker. Any time I do anything with the phone - surf, text, etc. - the music just stops. And even when I'm doing nothing it hiccups or just stops for no reason. I didn't have this on ICS. Many others have had issues related to the upgrade but I have yet to see anyone talking about going back. I'm ready to go back. The question is, can I? And if yes, then how?
