Im having a problem with the lcd backlight and figured I would ask here. I've had a v20 rooted since Dec of 2016 and luckily have been spared from many of the hardware problems other users here have suffered. Just today, after watching Youtube videos for about an hour at maximum brightness, my main display just went completely dark. With the backlight bleed over from the second screen, I could see my display, but without it on I can't see anything. I'm assuming the backlight has somehow become broken. I'm assuming the only fix for this is a screen replacement, which at this point I don't want to do. Just curious if anyone has had this happen, or if by a miracle this may be bad software that is fixable without replacing parts. Thanks to any and all info in advance.--Philip
Edit-Just now thinking it may have been a thermal issue. Phone is still noticeably warm about 5-10 minutes after a battery pull and being shutdown completely. Smelled the back of the phone and noticed a slight smokey scent. Potentially watching videos at max brightness caused a meltdown? Idk just trying to figure out what the heck happened
Edit 2- So plugging in the phone while powered off to check battery levels has wielded wildly different results. Fist time I plugged it in it was 5%. Then unplugged and replugged immediately and it was 30%, and now a third time it is down to 10%. Wondering if the battery could be bad? Don't have extras to test a different one, but the original shows no signs of deformation. Wondering if a failing battery could cause the main display to disable. Anyways just another thought
Hello. I know its has been a long time but is there any update to your problem. I am in the same boat.
Regards

The two weird issuse I'm having are when I touch the screen in the center a little more than half way up iget a circle ripple kinda like when you push on a laptops LCD screen. The second issue is when I use my camera or place a game even with full battery the phone shuts of after five min? The rom that I am useing is the latest typhoon rom this has been going on for like three weeks both issues started around the same time. Any help or suggestions are greatly appreciated. Thanks Kevin
The 5min shutoff sounds like its overheating... or the batteries going bad
As for the Screen Ripple.. I'm not sure... If you still have warranty consider restoring it to factory default and sending it in for a replacement.
the screen issue is weird indeed.
if you have SetCPU installed, make it notify you if the phone gets hotter, somewhere between 40-41 degrees celsius is fine, you can make it underclock the CPU to somewhere between 500-800 MHz so it would cool down, and you won't get that issue if it's an overheating problem. if it keeps turning off then I agree with the post above, it might be your battery.
yep overheated , screen ripple is caused from overheating.
Had a friends like that but luckily had a spare mainboard & he just got a screen assembly..
He too was on android but has decided to go with WM6.5.5 & see if device lasts longer on this OS.
Hi,
The screen on my Nexus 4 has started to stay awake. I've noticed my battery drain a lot quicker over the last couple of days and I also noticed that every time I pulled my phone out the screen was lit so I've taken it out and watched it. It just stays awake all the time. If I turn the screen off the minute a message or anything comes in the screen wakes and stays awake so near impossible to keep it off for any length of time.
I do have the developer screen enabled and had stay awake whilst charging option enabled. I disabled that to make sure that this wasn't causing the screen to stay awake thinking it was somehow on the charger when it wasn't however the problem persists even with that option unchecked.
I have the screen timeout in display set to 30 secs.
Anybody else experiencing this or no how to solve?
The phone is stock and unrooted though I plan on rooting later today.

Does it stay awake but go very dim? I have this issue too.
can it be caused by the screen protector blocking the light sensor somehow?
Can you install BBS (BetterBatteryStats) and see what's keeping your phone awake?
Sounds like a FULL_WAKE_LOCK is constantly being imposed on your phone.
Questions
Is it only when you put it for 30s?
What's around your pocket when you put your phone in it?
Do you have any attachments onto your phone? e.g. skin protectors, cases...etc
Does this occur on any screen or just your home screen and the developer options screen?
Though some questions may be obvious, the best method is to be thorough with the situation. Answering these questions will help us better help you.
My phone shut itself down about an hour ago (plenty of battery left as I had to charge it earlier and was at 50% when it did come back on). It took several minutes before it would respond to getting turned back on again. I've got 2 messages since and the screen is now tuning off as it should. I had turned the phone off a few times to see if it rectified yesterday however that didn't work.
The problems wasn't anything to do with me having it in my pocket as the problem still existed when I had it sitting on my desk. I have no screen protectors or case and I never put it in any pocket that has anything else in it as I don't want to ruin too quickly.
So not sure what's going. All seems very odd. Hopefully not a sign that the phone is on the way out but looks ok for now. Will have to watch and see what happens over the next few days.
Thanks to all who took the time to respond. Hopefully I won't need to bother you again on this issue but not convinced just yet
First I would like to say I can't remember how the keys are called, all I know they are the menu and back keys, and that they should light up for a second and turn off until used again.
I'm having couple of problems with my phone being awake all times, battery drain and mostly overheating.
Some hours ago, my phone was reaching battery temperature of about 42ºC while screen off and apparently "nothing" abnormal running in background. After restarting the device, first thing coming to mind was to put it in the fridge for a couple of minutes to let it cool down.
The problem is, 2 minutes turned out to be some hours. When I removed it from the fridge, I noticed the hardware keys weren't lighting up. Restarted, still nothing. They work, but won't light.
What could it be? Maybe the low temperature did something to it? Or was it condensed water from the fridge? What can I do to make them go back fully functional again?
Issue solved, the overheating made it go back working once more.
Maybe try putting your phone in a bag of rice for 24 hrs to draw the moisture out

Hello all,
Recently, since about a week, i've been experiencing sudden random reboots. Often when starting apps (especially the Camera is a real culprit here, but also Google Photo's). When entering pin-code all seems fine again. and sometimes i can just use the camera like normal. But sometimes it keeps rebooting and the only way to stop it is to quickly turn off battery saver (seems a solution till now for a while)
Searching online didn't really help much, as i found a few people with the same issue end of march also on Oreo update, but no solution yet.
Also the battery indicator seems off. it often drains reaallly slow (85% at the end of the day) and then at a random percentage (like 60%) just turns off. When turning it back on it only has 3%. So it could be battery related.
What i tried:
- Let the phone drain completely, then recharge to 100% overnight.
- Remove all apps installed in the last few weeks + all unnecessary apps.
I don't want to do a factory reset, because our IT then has to set up the Authenticator again which is a pain for them (and i already had them do that a few weeks ago :angel: )
Any tips on how to troubleshoot some more or more people seeing this behaviour?

That sounds kind of like a battery that's failing.
What's the age of the phone? And did you primarily use Huawei's supercharge brick or other methods / chargers? (I ask the second, because charging at 4.5A can be bad for the battery on a regular basis.)
I'd load up something like Ampere and watch the charge / discharge rates. I'd expect a normal discharge rate around 150-350mA, but it depends a lot on what you're doing. (GPS and moderate graphics will keep it up in the 800mA-1A discharge range, the rear camera with just the viewfinder seems to push 1.2A current draw.)
I'll give Ampère a try. I used both chargers but the phone is just over a year old. Nothing to warrant a bad battery already.
Besides that, recent discoveries lead to believe slow charging could actually cause more heat and be worse for battery. But again: it's a bit soon for something like that I think. I'll try Ampère first. But i doubt that's the issue.
I've noticed my phone gets toasty when fast charging. If it's hooked up to any charger other than Huawei's, it tends to stay cool.
And it happened again. More then 50 percent and then it turned off and only had 3 percent
Dead battery I guess?

That's what it looks like to me.
Fortunately, the batteries aren't that expensive to find (Google popped up a bunch for <$20), and actually getting in isn't too difficult either, if you want to swap it yourself.
Just to close this topic properly:
The issue got worse, but i was on holiday. Ordered a new battery with a toolkit to replace the battery for 30 euro's.
When i got back from my holiday i notices the battery had already pushed the screen loose. So getting the screen off was easy. Swapped the battery in just 5 minutes and now everything is working great again. The screen used to have some bright spots and those are gone aswell. I guess it was a giveaway of things to come.
Thanks for the help!
I been using this lg v20 for almost 3 years, and this is my only problem it gave me after those years.
Sorry for my bad english
My lg v20 had this problem just recently... Every time i unplug it from the charger it freeze if it doesnt its so laggy you cant even do anything like navigating to settings or so on... But when i plug the charger it turns back to normal... What could be the problem? ... I was thinking it was just the battery but the other one i used is just almost a week even the original battery can still last a day normal use without gaming... Is there any case out there like mine? Does it have a fix?
Btw im running los 16 + gamma v15 f800s kv
Thanks in advance
Try cleaning the USB port?
My wife's us996 had an issue and cleaning the port fixed it:
https://forum.xda-developers.com/v20/help/absolutely-terrible-battery-life-t3531456/post78654160
Itried cleaning but no luck
It turns out that when my phone starting to heat up its lags but when I plug the charger it turns back to normal... And also I notice there are some flickering on the screen specially on the 2nd screen
Well, to rule out a hardware issue, I would go back to a stock rom and give it a week or two to see if your issue still exists. If the issue is still there with stock, there's definitely a hardware issue, battery or otherwise.
Have you tried a battery monitoring app, like Gsam, Better battery stats, or accubattery? That could give you a clue on what's running/causing the heat issue.
I'm using accubattery and it seems there's no problem at all. My phone won't heat up unexpectedly thou but every time I play games or even doing intensive tasks that's where the problem kicks in. I also noticed while I'm tweaking at kernel auditor the CPU temp is 78c but the phone isn't that hot. Im thinking the thermal paste isn't doing its job and maybe causing the problem
