So, long story short, my phone's battery had a sudden death. After I had it serviced by a 3rd party company, it came back with the screen somewhat damaged.
Here are some pictures for example, using the display service test:
I can't prove they did it because I simply couldn't turn the phone up until they replaced the battery. The battery might have leaked or something. They obviously didn't take the blame for it, but they also messed up the usb port so they are definitely a potential suspect. But, if they did it, what could be it? Looks like it got stained or wet or something... Definitely weird.
That kind of display issue is typically caused by a polarizer that is warped, usually caused by applying pressure to the display when it is hot. It's an all too easy thing for an inexperienced or careless repair person to do while the phone is face down on the bench, especially if they heat the entire device to loosen the seals, not just the back, or if they cool it down too quickly. It's even more common if the LCD itself is removed, but they should not have needed to do that to replace your battery. You may be able to improve it some by putting if face up, using a hair dryer to slowly heat the display a bit (not too close and moving continuously), and then letting it slowly cool down. If you have a screen saver installed, remove it first. You may be tempted to try and "work out" the warping. You are much more likely to make it worse if you try, so I don't recommend it. If you do nothing, it may slowly reduce on it's own as well.

That might be the case. I can see the patterns shift a bit when I apply pressure to the screen. What is a way to confirm this? Could I do something with polarized sunglasses or something? If that is correct, the areas affected should darken/brighten differently from the rest of the screen.
I didn't try to mess with heating the screen up. Like you said, I might make it worse and I'm already really pissed about it. But I kinda want to try anyways. Where have you seen this before? Is it possible to fix it without opening the phone?
It's more common on tablets than phones, just because of size. I've seen it on screens that have been sat on but didn't break, but heat in combination with pressure is the more typical culprit. The sun or a hot car might do it if the heat was uneven, but I've not seen that. I'm not sure how you could confirm it. Maybe some sections will darken faster as a polarizer is rotated toward perpendicular to the polarized axis of the screen. Essentially, the glue layer between the polarizer and LCD panel is thinner in some places than others, so the polarizer is on a slight angle. In those areas, there is more polarization, and you see a darkness. The only real fix is to replace the screen assembly. The steps I gave will typically just help reduce, but never fully eliminate, the issue.
Unless they did a full, written inspection of the phone before you left it for repairs and you did a full inspection before walking out with it and noted the discrepancy then (which is always a good idea), your repair person is likely to continue to claim they did not do it.
The phone wasn't like that when the battery died. For obvious reasons, the screen couldn't be inspected before the company made the repairs. So I can't say it was their fault, although I'm pretty positive that it was. The suspicion is big because they also messed up the USB port pretty good. But, again, I can't prove it. It sucks because I wanted to sell the phone, and it was in pristine condition.

I have a screen problem, and because of the cost would prefer to perform the repair myself. (I've repaired a number of laptops and smartphones in the past.) My problem is that I don't know which part failed.
The accident: I dropped my Galaxy S3 from a height of about 3 feet onto concrete. For reasons too embarrassing to detail, I didn't have the protective case on the phone.
The result: The front bezel around the screen has a 5mm abrasion scratch in it, but the screen itself shows no sign of damage at all. When I put the battery back in, and powered up the phone, the screen did not come on. I see a faint line of green pixels about 3cm long on one spot on the screen. There is nothing else on the display. The phone seems to be powering up and down (not entirely certain because I had the phone on silent mode before I dropped it).
I'm hoping that one of you with more experience might have an opinion on any fixes I might attempt, or tests I might run to determine what needs to be replaced.
Thank you very much for your suggestions!
About six months ago, I decided (foolishly) to try my S5's water resistance by taking it into the pool and taking some underwater pics and videos of my kids. They turned out great. My phone, however, was not happy. I didn't notice it until about 15 minutes after I took it out of the water. I turned it off, removed the battery, let it dry out for a few days, etc.
After that, it seemed to work again, with a few small problems. The first was that it started shutting down all my apps because it thought it was overheating. I installed an app that monitored the temp, and the numbers it was reporting were obviously wrong (way too high). The second problem is that it would no longer charge. It would either warn me that the battery was too hot, or too cold, to charge.
After some googling, it sounded like the problem might be the USB charging port daughterboard that was the problem. I took a look at the inside, and it did look like that was the only part that got wet. So I bought a new daughterboard and replaced it. I ended up destroying my screen in the process, and only just now was able to afford a new one, hence the six-month lag time.
So I finally have my phone back with a new daughterboard and new screen..... and I'm still seeing the temperature issues
Is there any way in the software to install a "hack" or anything to tell it to ignore those warnings, so that I can actually charge my battery and stop the OS from shutting down all my apps constantly? Could the problem be somewhere else besides the daughterboard? I'm really hoping that my phone isn't just dead, is all
If the back cover and/or usb cover were not securely in place when you took the device underwater, then something other than the usb port is most certainly the problem. That, or you had the phone under water for too long. The S5 is water-resistant, not water-proof. I think IP67 rating is less than 3 meters for less than 30 minutes exposure, or something. When you had it apart, did you look at the board? If you didn't, I think you can remove most of the board pieces from the back. Them them out, inspect them for oxidation, and give them a cleaning with a gentle toothbrush and rubbing alcohol. If you put it back together and you still get problems, there's nothing else you can do to fix it. It might be possible to make the hack you want, but I'm not aware of anyone having made one. Maybe you'd have to find someone who could do it for you, or learn yourself.
I also exposed my phone to water, but the microphone went out. That part is not shielded against water for obvious reasons. I guess Samsung expected the mic to handle more than just a little exposure. But mine failed. So I just warrantied it. None of my water stickers were set off. For you, I'd recommend just getting a new phone if you're with T-Mobile. $0 down on something newer. If you really love the S5, maybe just pay the insurance deductible.
I used to actually fix phones for a living, but I never do just glass on Galaxy phones bc IMO it's just not worth doing. So I would've replaced my own usb port/mic if it didn't require removing the glass.
I wouldn't recommend trying a free warranty even if your water sensors are white, because they'll probably be able to tell the screen was replaced... if they check. Will they? I dunno.
I'd sell you my new warranty but you've already invested a lot in to an aging phone, so I think it's better to cut your losses. I think I have around 300-400 left on it. It'll be unlocked and come with a case and glass screen protector, but it's still a lot on top of everything else.

I know for a fact that in the S4 the daughterboard with the USB also has this battery temperature sensor in it because this was a repair I performed many times. Just change the board and the phone will charge and function correctly again.
I, however, have NO idea if it's the same on the S5. And apparently not, judging by what you experienced. I'm sorry you had to go through that and I know how much you had to spend on a screen. That sucks.
Good Luck!
A number of reviewers have noted serious issues with the ips lcd panel on the lg g5, specifically backlight bleeding and "blooming" (when pressure from touching the screen causes distortion). Has anyone else out there with the g5 experienced these issues? If so, will you try to return and get a replacement?
Have noticed neither of these problems. I don't ever run 100% brightness on the screen, then switch to a black background and go into a bathroom and view the screen. And, I don't press the screen hard enough to cause distortion. If you don't do these things, you will never notice an issue.

There is clearly a problem more or less with some units ( bleeding light).
And you don't need to push hard to cause distortion.
I have a very strangle faint vertical line on the right side. Not visible with a black background but looks almost blue-ish on a white background. Like a line of a very light shadow.
I've seen this issue too, but not enough to bother me. I didn't notice it with my phone until i read this post.
I think it's due to the design and battery placement. I think there's a very small gap between the battery and the screen, where the LCD is practically floating and when you put pressure on the phone, the screen deflects a bit until it makes contact with the battery. Otherwise, the battery would get scratched up if that gap wasn't there.
Yes, I have a 2nd G5 and it has the same vertical shadow, except much fainter. I wouldn't of noticed this new one if it wasn't for my first phone being so prominent.
Haven't checked for light bleed, but no bloom issues with finger presses whatsoever. I pushed as hard as I was comfortable on several locations and nothing. Also no shadow that I can make out and I am very sensitive to that kind of thing, especially if I'm looking for it.

I tried swapping out the battery & bottom-chin-thing between my two phones and now my original first phone that had the worse 'shadow line' has improved a little bit. So there's definitely a fault between the contacts that's causing this effect.
It just seems like such a mixed bag in terms of quality control Kills me too, since I've been super stoked for this device since MWC

I'm not completely sure what you mean by fault between the contacts, but i think the issue is due to very small and minute variance in battery shape or size. This variance is probably causing different pressure points on the bottom of the LCD screen causing the shadow.

Personally, I wouldn't call it bad quality control, but rather mechanical and structural design limitations with the materials currently available for use. The thickness of the G5 is only 7.7mm (0.303 inches), that's pretty incredible with a phone that has a removable battery. By comparison the Galaxy s7, is 7.9mm (0.311 inches).
I maybe speaking out of line here, but from an engineering point of view, I am impressed with the design. I am a little worried about the battery swelling up crowning the screen, but i guess i can change the battery if that happens. I've had some battery well up a little in the past...
I've had the phone for 5 days and the more i use it, the more i like it. Believe me, i'm looking for every reason to hate the phone while i still have 8 days to return it if i wanted to. After that, i'm stuck with it for two years.
I don't have any technical knowledge with this stuff but just thought perhaps there's some kind of interference or feedback happening near those plugs next to the battery inside that's causing it like when you hold a magnet up to an old tv.
The battery of my last two phones (Droid Maxx & Galaxy S5) both swelled up which is why I went with the only phone that offers a replaceable battery
FYI, I have a small magnet attached to the battery for my wizgear phone holder in my car. No issues with the screen when I press hard. There is definitely an interference fit now sliding the battery out, but it's not causing any issues.

I'm pretty sure a swollen battery in a G5 will absolutely destroy the phone.

Ditto. The issues AP and others have reported, I've not seen at all. My only real complaint is not being able to do tap to focus reliably on the camera.
I have the led bleed issue, but now I also have image burn in as well. you can see a faint update popup box and notification bar on the screen.
I'm assuming the phone updated last night, and when it finished, it never turned the screen off and left me with what I'm hoping isn't a permanent reminder of the update pop up ghosted on my screen.
LCDs don't burn in. If you have anything it is image persistence. Leaving the screen off for a bit (like overnight) and should clear itself.

I'm noticing it's going away on it's own by keeping the screen off, so you're right it isn't a burn in. thank you for informing me. I'm still getting it replaced however due to the backlight bleed.
A coworker of mine was given a G5 as part of an advocacy program. Within 3 days of getting the phone before the actual launch day, half the screen was unresponsive. We turned it off and next thing we saw was half the screen was showing the home screen, and the other half was stuck on the LG startup. Seems the G5 is having the same issue that LG recalled the G4 for.

I agree, i wouldn't call tap to focus a 100%, but one of my favorite futures with the camera, is the manual focus. I think that for me that makes up for it. Do you know if the s7 has manual focus?
ive noticed this im on my 4th phone from att. I love the phone but i cant deal with it it bothers me too much. i will be returning it soon.
Sometimes if my G5 has not been used for an hour or so, it is refusing to wake up from double tap, power button or volume button quick shortcut. Only plugging it in has seemed to wake it up on these occasions.
Has anyone else had this issue?
Not yet.
I am chocking this up to poor software implementation using the ambient sensor. I found similar issues that the OP was describing, and in my testing, was able to verify something is wonky with how the phone "thinks" it is being looked at or not.
Simply put, if you cover the ambient sensor and the camera (on my device) with your finger, while the phone is asleep/screen off, no matter how many times you press the power button on the back/fingerprint scan, the screen will fail to come up. The moment I introduce some light into the room (open up the sensor), I am able to get response back on the phone.
Ran into this issue last night and for the life of me couldn't figure it out until daylight hit . Also, my case might be obstructing the sensor (lifeproof fre), but I also noticed the issue with no case on.
Logically, I imagine LG was trying to limit power consumption with accidental presses, etc. If the phone knows it is in a dark place, it won't respond (because it thinks it is in a pocket or a bag of some sort). My rebuttle for this is how do they anticipate planning for night-time use of the phone, or are we limited to a daywalker only device?
I am heading down to an AT&T store and seeing if I can replicate this on demo units as well. In which case, we know the issue is inherent in the device (and hopefully addressed in a software update). If I am not able to replicate this at the store, then I bet OP and I got bad units.
Thanks for looking. If anyone has any feedback, or can repro or not repro this issue, please chime back .

I have also experienced this issue (opened a thread a week ago). I have the exact same lifeproof case and my problem occured at night as well. Phone did not want to wake up at all until I either restarted it or had some light in the room.
Same problem, same case.
What I have found is if you pull the phone out of the case it wakes up. Thinking proximity sensor.
Sent from my LG-H830 using XDA-Developers mobile app
Yup. It really doesn't take much extra coding for them to allow the power button to "Always Wake" the device... I imagine there will be an update in the near future.
As for me... jumping ship to the S7 edge. I really liked the G3, and was hoping this phone could have been that for me... Well, not like I really swap batteries out often anyway
Same case. Same issue. Take the phone out of the case and throw a blanket over yourself and the phone. (Simulating night) and my screen unlocks easy peasy. Something about this lifeproof case. You would think this issue would have been caught in testing and QC.
Yes the phone has a built prox. override. But it only becomes an issue at night. Outside of the case I have no issues with prox. sensor.
I have experuenced this exact same issue with my g5. Whenever its in the dark the power button nor the double tap will wake the screen when in the lifeproof fre case. When out of the case the phone works just fine.
Word to the wise though if you have a zagg glass screen protector and drop your phone both the screen protector and the screen with shatter even if in the lifeproof case. I just experienced this and now have a replacement phone. Just a heads up.

I have the rs988 variant and I have noticed this behavior when screen is in always on mode: if I suddenly change from light to dark by covering sensors, the always on clock goes out and nothing I do will allow it to wake up, until I allow brighter light again and the clock reappears. and I can use the double tap and power button again to see the screen. I also notice that the always on clock seems to have an auto brightness independent of the screen settings - I leave screen at 50% no auto brightness, yet I still see clock light levels dim in low light, One other thing - I notice that when I answer a call the screen blanks out (the way it is supposed to ) but does not reappear until I press the power button, just taking away from my ear does not bring display back; I also have the lifeproof case. and just removed it and verified my display now works when I take away from my ear; I just took some spray lens cleaner and cleaned all the surfaces of the phone and case with a microfiber cloth and put it back together and has vastly improved the issue, maybe gone, not sure yet. Update: seems like no matter how clean it is there is still a problem with the case doing something to the proximity detector, cleaning made it better. I can always wake up with the power button for the calling screen(sometimes swiping across top sensor too), wonder if the sensor is a passive light sensor or active (rf/infrared emission)
Same issue here same life proof case however it's getting worse as I am a mechanic and this phone goes through greasy hell. The plastic lenses on the lifeproof case are getting scratched and it's getting worse. It is also having a hard time autofocusing through this case. When you pull it out the phone is gorgeous and looks brand new. Good case but it has some downsides. Still better than a broken phone.

There are allot of other cases you can use but not waterproof. That really sucks good thing for this thread I was going to buy a lifeproof case. Using a otterbox defender right now. Thanks for the post guys saved me some grief.
still under warranty?

if still under warranty, see if they will honor it. They did with mine but that was right at the beginning when these problems were linked to the case; mine was in the first 3 months, but the new one worked well for a while, now a little flakey again but not enough to bother me...too bad, a great case otherwise

It's not a bug and not poor implementation. Its not light for "dark rooms" lol.. As far as I know it's the proximity sensor. When it is blocked it means the phone is in a pocket or bag and should not register taps. It really makes sense. If you dont xover the sensor and double tap doesn't work ..well.. Well, eother you have defective device or sensor , or the sensor is blocked (maybe bad screen protector?). This didnt happen with my G5 even once. It works 100% (assuming I tapped the same place)
Are the problems as described in this thread still manifesting on current firmware?
Got the phone today, liking it so far. I dont have any huge build quality issues, a little warping on backside of chin, but you really have to stare. Overall fairly minor when comparing it to how youtubers were reacting.
Now I did notice one thing when I pulled the battery portion OUT. When you have the battery and chin still connected to each other, and you hold it either by the battery itself or just the chin, do the two parts have a slightly loose shake between them where the plastic hooks meet? The battery functions/charges fine, but Im not sure if thats how all the g5 models are , or if they are supposed to sit tight together with no noticeable movement ?
Now just a heads up, I am shaking the battery/chin to feel the loose movement. I figure its just how the hooking system is designed where it cant be flush, but I just want to double check if I need to swap this unit out. Cosmetics are one thing, but Im not messing with a battery/chin that may give me more issues down the road.
It's fine. Relax and enjoy your new phone.
If it was flushed tight, you probably won't be able to remove the battery from the battery adapter.
You have no problem there.
