I have this strange problem with my LG G2: when on default mobile network settings, I cannot receive calls and SMS messages. I can however make calls and send SMS messages. I have to force phone to only select 2G/3G in order to be able to receive calls and texts.
This happened after I upgraded to Lollipop, it happened for a while in V30A and now it happens all the time after upgrading to V30B. Phone is stock, never rooted. I have the International Unlocked version and I am using Orange as my mobile operator (in Europe).
Any idea ? Thanks !
