I recently updated my device to the new OS, which i am liking the interface on. However now when i use music streaming applications they all fail in their own unique way. Pandora says that it can't contact the streaming server, iHeart Radio will stream a song and then stop, Samsung Milk Music will start to stream but then it will hang up and stop loading the song. Also my email is taking a long time to sync up, i have re-added my accounts to no avail. Finally some applications seem to need to be started several times to actually communicate with their servers. Is this a known issue or has my phone installed the update with some sort of error. Can someone please help me with this!!? I have tried to clear the cache and again that did not help. If these issues cannot be fixed is it possible to revert my phone back to the previous OS.
