I think I discovered what seems to be a critical software bug regarding the signal of the LG G2 in weak signal environments.
In my house, the signal is generally very weak. However, it is usable. But when the phone shows 0 bars of signal due to it being placed in a very weak signal spot or hands covering the antenna, the signal strength never comes back and my number cannot be called until I take one of the following actions:
If I turn the Wi-Fi off, the signal comes back instantly. If I make a call, the signal comes back instantly and I can make the call. And if I turn the airplane mode on and then off, the signal reappears.
This has never happened on my Nexus 4, and it only happens inside my house where I have a weak signal.
Any ideas regarding the resolution of this ? Can I boost the signal sensitivity from somewhere in a secret menu ?
I hope that this issue will be solved in an upcoming update, but I can't be sure.
PS: I am running the International version of the G2, on Vodafone Romania.
