I have a CLNR GN, and its signal, data loss a few times a day and 3g/4g handoffs are horrible in weaker signal or4g fringe areas, both happen to be at work inside the building and inside my apartment. The only thing that has made the phone stable being bone stock is to switch the radio to CDMA only. Since then I have had no issues at all, but it really should not be this way. It should work excellent in CDMA/LTE mode.
