Problem with LG G3 858HK (dual sim)

Apr 8, 2017 2:39AM PDT

I have a problem with LG G3 858HK (dual sim). Sometimes (once/twice a day) phone loses all signal, tries to connect, connects and loses signal again, again connects, loses and so on, and so on. It’s not only data, it loses mobile signal as well. And it happens in all kinds of areas, even where signal is full 4G. Usually nothing helps, except switching the phone off/on again or pulling the battery. Sometimes when switching it off while having this issue, it wouldn’t switch on again pressing power button. Again, opening it up and pulling the battery helps. Sometimes only connecting wifi/ disconnecting wifi helps. Phone is running rooted android 6.0 (tried few ROMS, rooted/non-rooted - same thing). I tried everything to solve it: factory reset, changing sims, running with one sim, running with 2 sims (its dual sim phone), un-rooting, rooting again, multiple ROM's, tried all kinds of settings - nothing helps. The issue is probably with the phone. Sadly, warranty is expired.

The signal in the area where video was captured is really good, full 4G normally. Anyone got any idea what could be wrong with it? Any help would be appreciated. Thanks.

I was on Sprint and in the end it was not the phone but the carrier. Since you have a SIM, try the SIM in another phone.

Thats strange.

Well, ok, I'll try SIM of another carrier with this phone. I know my SIM works fine with another phone. Strange, never heard about incompatible phones with certain carriers.

For example if the carrier has certain bands and your phone doesn't have all those bands....
Or the phone has some odd failure. Really tough on folk.
