Signal problems

Hi, I have problems with signal. Specifically with LTE. I have strong signal,but when I switch off the display and after a few minutes I turn it on it is often offline! I tried switch it to 3g and everything seems fine. I think there is some problem with 7.1.2. Does anyone has this problem?

  • Yes, i have the same problem. Often when the network is being used for hotspot connectivity and a call comes in, the internet gets disconnected and when the call is over it starts working again. Throughout the time signal shows 4G and full.
  • Isn't this just the phone switching to 3g to handle the call? Something they all do when VoLTE is not available.

  • No, it is offline when I turn on the display.
