ever since updated to iOS 9.2, I find my cellular connection to be very finicky. if I'm in an area with spotty service, the phone will "forget" to switch back to LTE once service gets better. it'll stick on "4G" which is usually unusable in LA. several times a day I have to go into settings and turn Cellular off and on to fix the problem. the phone will immediately find the LTE network and stick to it. this is only after updating to 9.2. using an iPhone 6, iOS 9.2, on AT&T anyone else having a similar experience? had the phone over a year and this problem is new.
