Was really disappointed when I had so many issues. Data was spotty and dropped all the time requiring a reboot to reconnect, switching from wifi to data would cause the data to drop requiring a reboot to reconnect, and just not using the phone for a while would cause the data to drop requiring a reboot to reconnect. Tried rerooting and reflashing, both did nothing. I'm 100% positive I have 3g/4g service at all times because my sister has an unrooted bionic and she always had 3g/4g. Going back to stock until I can figure out a way to get it fixed.
