My G5 is about 3 months old. Last week it installed an LG software update. Since then, whenever my signal gets weak or lost (such as in the subway or a basement), it does not reconnect back to LTE once I have a strong signal again. Sometimes I will get a phone signal but not data, other times I will not even get a phone signal at all. Once I restart the phone, everything works fine again.
Toggling mobile data on and off does not work. Turning airplane mode on and off actually makes it worse (I lose signal entirely). Wifi connection is fine.
I have tried resetting the network settings, no change. I then did a factory reset, no change.
This happens several times a day so it is very annoying having to always reboot my phone.
Does anyone have any advice, or will I need to replace my phone under warranty?
The problem seems having been solved.
1. WIFI calling needs to be turned off. Otherwise the data connection can be lost at anytime.
2. VoLTE (Woice over LTE) needs to be turned on. Otherwise the data connection will be lost whenever a phone is made.
Hope the informaton help!
