i just got back my lg g4 that i sent to the service center last week.
they change the motherboard and the screen or the whole phone since some of the dent made by me is gone and some screen scratches (mine is not bootloop issue..just screen autoclicking).
now still checking on the phone..apparently the warm issues still there although they fix the auto-clicking stuff.
its android 6.0 and V20c-sea-xx..
how to check the mobo they give is 1st gen or 2nd gen or not so problematic gen?

*Updates*
not sure if ever ask this question before, but any brand for screen protector taht doesnt block the sensor and fingerprint free?
