´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. Its 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, excepts switching the phone off/on again or pulling the battery. Sometimes when switching it off while having this issue, it wouldnt 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), unrooting, rooting again, multiple ROM's, tried all kinds of settings - nothing helps. The issue is probably with the phone. Sadly, warranty is expired.
Video of the issue: https://www.youtube.com/watch?v=qq7_jm0-Hp8
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.
Hi, I think it's board problem and not software problem
In my G3 D855 I already had the following problems:
Loss of wifi signal unable to connect to wifi:crying:
Invalid SIM card and does reboot:crying:
Blue screen and reboot:crying:
Of the various solutions I saw on the internet that gave the best result was to apply heat to the motherboard with a heat gun.:good::fingers-crossed:
Be very careful not to burn anything or drop any component
Place the motherboard on a flat surface and do not touch it
I applied heat all over her for 15s
I let it cool down a bit
Apply heat again for 15s
Let cool and reassemble everything and test.
In my case it resulted
I stopped having problems with wifi and blue screen, but after 15 days.
Started giving again invalid SIM card error and reboot.
I returned to heat on the motherboard, but this time gave more heat on both sides of the motherboard, more on the side of the SIM card slot (in front and behind (see images)
Running for 3 days without problems.:fingers-crossed:
