LG G4: Replace Glass Over Camera?

Wed, 17 Feb 2016 13:58:46 -0700

Today, I unfortunately cracked the glass over the camera (lens?). I watched the video of the G4 teardown and a video on replacing the lens in the G3, and it looked really cheap and easy. Is there anywhere to get the replacement parts for the camera yet?

LG G4: Any way to replace the smooth plastic bezel?

Mon, 24 Oct 2016 14:08:25 -0700

I dropped my lg g4 today and it held up pretty well, it was not from a high height, as I was getting out of my car, and did land on the back but the plastic bezel was dented in two places on one side of the phone. I could just get used to this cosmetic damage and still use the phone, but I was wondering if there was any way to remove the plastic bezel and then replace it.

LG G4: LG G4 Camera won't focus

Sat, 19 Mar 2022 20:31:47 -0700

A few days ago I dropped my phone and now my camera refuses to focus. Even on manual mode when I try to adjust the focus it stays at a constant macro focus- everything is always blurry!

Any ideas on how to fix this? I've tried replacing the rear housing but that didn't do anything.

How would I go about fixing a cracked glass screen on an Android LG G4? It works fine but I accidentally cracked it while I was cleaning the case. Also, where would I go about finding the parts for a glass screen? Thank you so much.

LG G4: What hardware is causing screen splitting issue on LG G4?

Wed, 22 Feb 2023 11:04:36 -0700

I did a screen repair on a LG G4 because the screen was displaying a vertical split. I honestly believed that the lcd was at fault because usually that is what would cause something that looked like that. I replaced the screen only to have the new screen do the same thing. I have read tons of forums to find out that this is some kind of hardware issue, but have yet to find a solution. I am positive that it is hardware. But now I'd like to know what to do to fix it. There has to be something I can do. I watched a youtube vid of a person just holding a phone with this common issue. I read in the comments that somebody had heated the 'screen contact' on the motherboard (his words, not mine), and that worked for him, but he has no vids explaining that and no further comments on the vid. Any suggestions? To be more clear, half of the screen is either static or frozen.

I never really solved this issue and it was returned to the customer. However, I have some better theory as to why this happens. My suspicion lies on the LCD connector itself, although I can't be sure as I no longer have this phone. It would be really helpful if someone could get some close-up pictures of that area. I'm sorry that I didn't :*(

LG G4: LG G4 screen turning itself on after timeout

Mon, 21 Nov 2022 13:05:14 -0700

This issue started about 3 or 4 days ago for the record. I have been trying to find a solution online but I have yet to come across a real solution (other than sending it in to LG for 9 days (completely unacceptable)). It happens whenever I turn the screen off, either through the lock button or the double tap. The screen will power off correctly and then turn itself back on within the next second. If i leave the screen to timeout at 15 sec like I have it set to, the phone will dim and then the screen will close, only for the screen to immediately turn itself right back on. This is killing my battery life and making my phone constantly overheat. If someone has found a solution please share it with me, I am reaching my wits end
