Strange Behavior of Screen - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

P3110 white 8 gig
purchased from carphone
noticed later on that the screen back ground is behaving ab normal
the led is going up and low but if i look closely i can notice it the blink is very rare, but i can feel it in a part of second...specially when dark back ground etc youtube or any dark wallpaper..:highfive:
and some slight sounds also being noticed when switching between pages
i found it weird when i compared with the same model but black colour
been to store asked them to replaced they gave me another new one, but same problem i figured out its the issue with color or its normal with every white P3110 8 gig
just need to know
cuz this led illumination happened with one of my old satios caused dead after couple of months.
please add comments as per ur experience
thanks

Weird vertical lines after watching video on Netflix

I bought my SR 2 nights ago and last night, decided to test out Netflix on the phone and as soon as the movie started, I noticed that the quality of it was not that clear (or as clear as I would expect it). I then noticed and my dark wallpaper had these strange vertical lines on it and would not move. It is now there all the time (noticeable with dark colours) and even turning the phone off for some time, they are still there - is this a burn in issue? Has anyone else experienced this?

Flash always lit?

Anyone else have their flash led always dimly lit? Even when the phone is off my camera flash is dimly lit.
This is most likely the heart rate monitor. There is currently an issue with Google Fit and the S6 which causes the heart rate monitor to stay on. The only solution st this point is to uninstall Google Fit until Google releases an update that fixes the app.

I'm not sure Google Fit is the only possible source for this problem.
I have the same problem as OP. I got my S6 (non-edge, 32GB) about 24 hours ago and last night noticed the faint yellow glow on the back of the unit. I haven't been impressed by the battery life (admittedly a very limited time with it so far) - but this could explain the less than stellar battery life so far.
I don't have Google Fit installed (in fact if I go to the play store, I get a message saying that it's not compatible with this version"). S-Health is disabled too.
One other thing, when I use the flashlight feature, I notice that the light isn't nearly as bright as on the S3 - not sure if this is relevant, it is the same LED.
I rebooted the system, and even turned it off, the faint light stays on. If the unit wasn't sealed I'd pull out the battery just to confirm this light can go out :-/
I have this issue on mine as well. I first noticed it when I went to charge my phone over night next to my bed. I lay the phone on its face so the LED notification doesn't show. I noticed a slight glow from the flash diode. I thought at first it only happened when I was charging my phone. Today, while at work, I powered down my phone and again noticed the light. For me, its always on. I just got off the phone with T-Mobile and they are going to over night me a replacement. I mention this thread to the T-Mobile support rep and she looked it up while I was on the phone with her. My friend's S6 does not have this issue, so not all of them are having this. I encourage everyone to go into a dark room and check your flash diode.

Just dropping into say I also have the issue . 32GB, Standard S6, T-Mobile. I will call them and get a new one overnighted as well.

No disrespect taken, man those are hard to get off (thanks for confirming this, it looked like there were).
However, that might explain the flashlight function being a bit dimmer than on the S3, but it wouldn't explain the constant light source itself.
How can we possibly check this in store where there is substantial amount of light anywhere. I'd definitely check my S6 in store for this.
Mine doesn't have this dim light at all I checked and I closed all the lights to make sure nothing is coming out . I don't know I wish I can help

I think it would be difficult to see unless you ask them to let you into a dark storage room without windows That's how I can verify mine is still doing that during the day, though at night when I wake up with the phone next to me, the glow is comparatively quite substantial.
Plus, you'll have to wait about a week before you can see them in the store.
I have two S6's and can confirm both of mine has this dim lit light only noticeable in the very dark.
The problem with us getting the device early is we don't know if this is hardware or software problem., that might get noticed and fixed with an update. Many say after the actual launch Samsung/Tmobile pushes an update. We can assume they at least will to fix the cell standby draining battery with VOLTE issue. Plus how many will we have to get shipped to us before we get one that doesn't do this, very different than being able to have the associate check it in the back office with lights off.
Can anyone that did get a replacement comment on this.

Mine is doing it too. If it is indeed the case that not all GS6s are doing this, that does make me concerned that somehow my unit is defective. I'm wondering if I should just hold onto it hoping that Samsung will fix it with a software update or if I should try yo exchange it.

I spoke with a tmobile rep. He said online orders get 20 days return exchange from the day of delivery not purchase. He also said there should be an update on a day or two after the official April 10th launch. I told him to document my account that I called about this issue. He said I could get another (two) overnight to me, but there's no way to guarantee if the new ones won't have this.
How come more people are not jumping in here to say theirs is doing it too. If its just us few maybe we do have a problem. But giving it's only noticeable in the dark maybe they haven't seen it on theirs?

I think you are right, unless you have the phone next to you at night you probably won't notice it., still odd, I would have expected others to notice it too. And, even as dim it is, it can't help with battery life. I hope it's a software issue and can be easily patched that way.
Edit: just noticed tonight that my phone does in fact have the LED issue. It's odd because I spent some time yesterday in the dark looking for the problem and it was no where to be found. Been laying in bed messing with my phone while it's charging, decided to flip it over and low and behold, dimly lit flash on :/.

Mine does not seem to be having this issue. I checked it out last night in a completely dark room and couldn't see anything. To see if I could get an idea of what it looked like though, I turned on the torch for about 20 seconds, then turned it off and looked again and it did replicate the faint glow that it seems most people are speaking of, however it faded away in about 30 seconds.

This is making me think some S6s just have this defect where the LED never turns off and some don't. I think it might be best just to return my S6 and repurchase the phone after its official release date. I think these earlier phones might be more prone to defects. My gut feeling is that this is something that won't be fixed via software. I don't think exchanging the phone for a new one will help too much given that so many other S6s also have the issue, you have a good chance that the new phone you get will also be defective.

My guess is it's a hardware issue (perhaps they used a different supplier/component for this part) since all of the phones are presumably running the same software (some with the OTA update that was waiting from T-Mobile - like myself, others perhaps without it). If it can be patched with software is another issue.
Actually, perhaps it would be useful to know if those experiencing the problem have applied the OTA update and those without haven't. My hunch is it won't be a factor, but curious, so people reporting should state their situation.
For my non-edge S6 (black 32 GB) I have the OTA and my flash stays on dimly all the time.
I noticed this last night and I thought it could have just been some sort of burn in from using the flashlight. (64gb regular tmo S6)
It's basically impossible to tell with any sort light around whether or not this is happening, even just with residual light, but mine does seem to be dimly lit in a pitch black room.
Could it have something to do with the selfie feature on the camera? Using the heart rate monitor as a picture button, that is.
I have a 64 GB T mobile regular GS6 with the OTA and I do have the issue.

Pixelated Screen Glitches on certain colours in certain apps. Not on Screenshots

hey guys
so a month ago i smashed my OPO and decided it was worth it to spend the 50 bucks and repair it myself. Im rather experienced in taking apart phones, computers etc so it wasnt a big deal. So i ordered the whole screen + frame and a new battery from ebay and put it all together. No problems at all along the way, everything went smooth. But while setting everything back up software wise i noticed these horizontal pixelated graphic glitches that only showed up in certain apps but always on the same spots over images (camera, images, video). Searching xda and the web in general resulted in nothing. (the stuff found when searching for "OPO pixelated lines; graphic glitch shows an issue unrelated to this(atleast i think)).
Ive tried everything from OOS to fullstock kitkat to 3 different custom roms and several different firmwares, but the problem persists. Is this a hardwarefault with the new screen (damaged plug/cable) or did i somehow damage the logicboard?(i was perfectly careful and as i said.... it went swimmingly)
heres a video
thanks for the help

Should I go to T Mobile for replacement?

I have only had my phone for about a couple weeks if not more, and it already has screen ghosting. I'm kind of afraid that they'll give me a more faulty G5. It happened with my girlfriend over and over, every replacement she got had rebooting problems. What should I do?

I personally wouldn't bother doing a replacement. Download and use blue light filter app from play store, which will stop the ghosting issues from happening. Also you can use screen burn in fixer apps from play store and let it run for a couple hours to fix your current ghosting or just let it with screen of for awhile like overnight or so and use the blue light filter. It's not actually screen burn in so just use the blue light filters. You could also unlock your phone and use a custom ROM and they have built in settings of LiveDisplay where you can manually adjust RGB settings to help.
I lived with the blue screen filter app for the 6 months I've had my G5 and then I cracked the screen, bought a replacement and got a perfectly working one, it honestly looks amazing and it's great not to worry about ghosting anymore. I've found the LiveDisplay settings and even color corrections from AOSP roms had no influence in ghosting, the only reliable way was the blue screen filter app, also there is not an app that works when in recovery or at startup optimization. I'd say go for the replacement.

Just something to be aware of is that it sometimes doesn't happen right away. I had my G5 for 6 months or so before having an issue with it. I've seen many others report the same while others had the issue within days. Even my girlfriends g5 was okay for about 8 months and then had the ghosting issues and I had to use blue light filter app for her since she's on stock. Also LiveDisplay works just fine in aosp ROMs to fix the issue if LiveDisplay is actually working in that rom (some ROMs it's not working on and none had working live display up until a couple months ago. I use it on RR and have no issue with screen ghosting now. But either way op, it is up to you.

Yeah my mistake when I said LiveDisplay has no influence, I meant to say that even though​ I lowered almost to 80% blue pixels in color calibration and using LiveDisplay at the same time ghosting still existed (less noticeable), at least for me. Using blue light filter app removed it completely.

Ah ok. Yeah I found only lowering blue pixels will not work. Instead I lower all 3 to 90% and it's completely gone. I figured that since the blue light filter apps lower blue pixels that would work same with LiveDisplay but still noticed it, so I tried reducing all 3 and it worked. Also changed from Auto mode to day only settings to get rid of yellowish tint LiveDisplay uses at night time.

Display Issue on two Note 20 Ultra

I bought myself a Note 20 Ultra Snapdragon Version (Hong Kong Version). After around 2 weeks right we’re the proximity sensor is, a dark discoloration started to appear. It’s not super good visible, but still it was there. I tried to overlook it but couldn’t. So i started a repair/exchange process. After a huge war to get a perfect device the shop where i bought the mobile exchanged it with a new one. But again after 1 week this weird dark spot started to appear. Sometimes the splotch is faintly visible, sometimes he is very visible. Now i have payed 1300 Dollars but can’t have a perfect display. Anyone having the same issue?

Ask yourself , what rogue apps are you heavily using that cause this issue. These things normally occur during using VoIP apps on high brightness with screen left ON for long durations. Heat , bright screen and VoIP apps that use the proximity sensor continuously degrade it.

First i use the mobile on very low brightness since i got it. Secondly i used nothing like the apps you described. So i can’t see how i caused this. And I’m not the only one. There are other cases with exactly the same issue. It’s a design flaw.
I forgot to mention that i carefully checked the battery temperature and cpu temperature all the time to avoid unnecessary strain on the display and the internals. But still after a short time on both mobiles the same issue.

Lol i own the mobile max 2 weeks. In this two weeks i watched videos. I used whatsapp for texting (maybe 2-3 phone calls). I used a video player to watch download videos, but i used nothing that would have left the display on for a long time with the proximity sensor working. I used the phone more for media, because i still own my iPhone 11 pro max for phone calls and alike. Hence i can’t explain why this is happening. I’m the first one who would say yeah i used the apps you mentioned on high brightness all the time, but that’s not the case.

Btw your sarcastic questions are unnecessary. If you think your clever and everyone else is a moron, nice for you. But the Note 20 Ultra is not my first mobile, and i know what to avoid, and what to do in most cases. But when i get the same issue two times in less than 2 weeks without doing anything maybe causing this, i think it’s ok to ask if anyone else is having the same issue.

Screen Issue!
So the other day i got a call on viber (a calling app) and when you get a call the status bars not transparent so it was still black anyway after the phone call i noticed a black dark pixel on my status bar and it annoyed me it was on my home...

No worries bubba. I hope you find an amicable solution soon.
Yeah every n20u has it. Some people just don't have the eyes to see it or choose not to / conditioned to ignore it.
I can see it on demand but I forgot it was even there till this thread. No way around it, it's a design flaw of this generation.
My n10+ isn't visible unless it's being used but what can we do, Nothing.
My US Note 20 Ultra has that as well. I didn't notice it for 3 months, then there it was. It is from the proximity sensor, and it's only visible in dark environments, and on days when I've had long calls. Other times, it's not visible at all and I'm guessing the sensor is under the screen and that the visible flashing causes it to slightly offset the AMOLED pixels. Every Note 20 Ultra I've seen also has image retention issue (not to the point of burn in) but high contrast images fade off the screen for about 5-10 seconds and this is only visible on gray backgrounds. Looking for a "perfect" one may be a waste of time.
