I bought Item IF303-050-1 (Wrong item arrived, IF303-049-1, just in case it has to do with it), but when I went to put it on my phone, the plastic ring, part of a piece of plastic that has 3 holes in it, (behind cover on IF303-051-1) got in the way.

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

LG G4: Camera of my LG G4 has trouble focusing

Wed, 06 Apr 2022 14:07:46 -0700

I dropped my phone, and now my camera isn’t focusing. The camera doesn’t look physically damaged, so I replaced the midframe, but the problem didn’t go away. I also tried reattaching the connector of the camera.

Does anyone of you know a way to fix this problem? I added a photo and a link to a GIF for reference. Thanks!

My phone is intermittently going bezerk! It opens apps, dials contacts, types nonsense without being touched! I have tried a new battery, restarting the phone, opening in safe mode and doing a factory reset. Would it be a hardware issue, and can it be fixed?

LG G4: My phone got wet and now has red, black and white vertical lines

Wed, 06 Apr 2022 06:42:04 -0700

So my husband placed my phone on a camp chair and our dog proceeded to spill water on it, I thought I got to it fast enough, dried it off and all was fine until I set it down for about half an hour and when I came back the screen now is red, black and white vertical lines, and it is unresponsive to touch, it powers up just fine, so I have been soaking it whole in rice for two days, with little improvement, so I carefully opened it up separated the mother board from the screen and diditizer and cleaned with isopropyl alcohol, I have placed it back into the rice, I have already orderedba replacement LCD and digitizer, but I am wondering if there is anything else I can do to get the phone to return to normal? I love this phone, my husband told me to get a Samsung like he has, but I didn't want one and love the red leather look on the back of my G4, so any additional help and advice will be gratefully accepted, if I have to I will buy a brand new G4 again, but don't want to if I don't have to.

LG G4: Why is only parts of my screen responding to touch?

Mon, 04 Apr 2022 07:32:17 -0700

Only areas of my phone screen responds when I touch. Apps or buttons that are on the insensitive part of the screen do not open or respond when I click. It has limited my phone use drastically.
