Has anyone experienced this problem before? I've been getting 4G/LTE no problem in my apartment, and then this morning I woke up and I can only get 3G... I have no idea whats going on. In my Mobile networks the CDMA/LTE is selected. Also, I went into the LTE settings (where you can run a ping test) and at the bottom for the Set Preferred Network Type: I have GSM/CDMA auto (PRL) selected. The other choices at GSM Only, WCDMA only, GSM auto (PRL) CDMA auto (PRL), CDMA only, EvDo only, and unknown. Anyone have any ideas? EDIT: What the hell... I just plugged my phone into the charger and I got 4G, then I unplugged it and its back to 3G. Help?
