Such a strange symptom in the LG G3 - the display slowly and gradually goes out, but not completely, i.e. it will not go out completely. The image remains gray, not black as when the screen goes blank. The touch doesn't work at this point. The display can only be reactivated using the button on the rear. When the screen goes blank (not completely) and I call the number of the SIM card in this phone, because the phone is ringing normally, there is also a signal at the calling person. However, the display will not turn on automatically. The phone is already under warranty (it is about 3 years old). So far, everything was fine, I didn't touch the software. What could be the reason for this behavior and what repair costs do I have to consider? Do you recommend a good and fast service where they will fix it?
