    Hello I'm suffering from one nasty problem while using my LG G4c. The problem is that sometimes my phonr screen goes black and locks.. and If i press unlock button on my phone's back, the screen turns on TOUCH and screen flashes, and yeah, I can try to unlock my phone but then after a few seconds it just flashes and I have to again press that unlock button and try swiping, but after 12 or so times (varies from time to time...) it unlocks and keeps working. Although I found 2 workarounds. 1) When I plug in ANY power source in ant after a few seconds I remove cable from phone. It 'cures' my phone, but still, it is really a pain always have to carry power bank and usb cable to endure day...
    The other workaround is lock screen. When I disable lock screen. Well. No PIN, No Swipe. No any secure method., then problem gets fixed but still has small probability to start working. So... Why is that, and how can I fix it? I don't know how to google this problem :D

    I am not sure but I think that your phone has been damaged by water. My old phone did what you said but the only thing different was that it never turned on after going off. I had to either keep my phone charged or ask the display to never time off from the settings. I suggest you to get your phone checked by someone.

    Possibly a fault that's related to temperature. It could be a control/driver chip in the screen that only works when heated.

    A common technique in fault finding electronics is to heat and freeze components, particularly semiconductors.
