Has anyone done any type of warrantied replacement on their S7? I'm on tmobile and my screen backlight keeps going completely dark at random times and then comes back on. The touch functionality still gets response, but the screen is black. Then the backlight will turn back on again after a while.
I called Tmobile and they said I'll be getting a refurbished phone as a replacement.. Not really too confident in getting a used phone that had god knows what problems before being refurbished.
Can anyone share their experience with replacement?
Did one in Dec. TMO sent me a refurbished one and was like new. Could not detect any cosmetic or functioning problems. Looks and feels like a new phone.. Been a month ago.
Wait a sec here. S7 doesn't have backlight. This is AMOLED screen - so each pixel shines for itself. What you experience is screen dimming. Check if you are or something is not obstructing the sensors left from the earpiece.

i don't have anything that dims the screen. the touch feedback works while the screen is dimmed like that, so its not completely off. its very strange.

I just noticed today a rectangular area on my lcd screen where it looks like oil on water. It's basically a rectangle w/ a half inch border of the "Normal" screen. I can see it from any angle as well as when the phone is turned off. The phone and the touch screen both appear to be working fine. The distortion will react to pressure on the distored part of the screen as well. I'm thinking some moisture got in my phone some how (although I can't for the life of me think when I could've gotten moisture in there). Is there an easy way to fix this or should I call up ATT support to see about sending it in to have them fix it? What's the general next step? I'll post a pic when I get home to my camera. I've had the phone since the first of the year and am currently using EnergyROM 2.0.
Thanks a ton,
Patrick
I haven't seen anything like this before but if it it was you say its probably moisture inside or even oil. Wait a little and see if it clears up, failing that give AT&T a call.
Holy Crap
Dude i have the same problem with mine sometimes, and i thought i was the only one!!
Its almost like the LCD screen is getting some burn-in. Even on a black screen you can see the shadow of an image, using touch flow 3d/2d its about half of the slider bar on the bottom of the screen. Did you also notice that the screen is flickering VERY slightly in the same area, but not on the rest of the screen? You have to try REALLY hard to see it. Almost like when you use a camcorder to see a CRT monitor's refresh rate. I had a feeling from the beginning that it was moisture causing this, because i do have the bad habit of taking my phone in the bathroom when I shower. My LID has turned pink because of the steam.
What makes me think it could be screen burn-in, is that I always keep my backlight as bright as possible, and once i see this start happening, i can turn my phone off for a few minutes, turn it back on and it works just fine with no image shadow.
I actually have been thinking about using my insurance to get a new phone because of this, and making sure i don't shower with the new one.
It's a known issue of the phone. I was able to get mine replaced, but I had it less than 30 days. You should be able to manage to get them to replace it if you make them look up known issues with the phone.
Sorry for the inactivity, I've been spending my days pulling Cat 5e in attics and haven't had much computer time at work / energy at home - I'm going to get in touch w/ ATT sometime this week and see about arranging a replacement, I'll post my results.
i have the same problem. near the corners i see very slight flickering as if the refreshrate can't handle the tf3d.
it most likely because of the themes. when using all of those non-original themes, it' shaving to load all the images, causing it to have very very slight lag. maybe?
it's rediculous, with the price of this phone, you'd expect higher technology for the screen.
Your digitizer is touching the LCD because too much pressure has been applied to it, probably in your pocket.
What you are seeing are Newton's rings http://en.wikipedia.org/wiki/Newton%27s_rings
I think we're talking about two different problems here.
First, you have the rectangular area like the topic starter described and may indeed be what bubble said. However, they are not rings... its a true square (at least for me).
Second, you have the flickering issue. I have this myself sometime at the position of the menu bar. Opera seems to be the only app that triggers this for me though - then i get flickering Opera 'burn in' like effect. This will eventually disappear again after keeping the phone off for a few hours, then on with the screen off. This effect does survive soft-reset and such.
Newton's rings is the name of the observed optical phenomenon. It has nothing to do with it's shape.
I know that in this case it appears on a square section of the screen (I face the same issue and I already ordered a replacement screen).
Is there a solution to the flickering and screen burn problem? I didn't notice it until I had loaded a 6.5 rom and was using the light colored R&R theme. I could then see flickering in the bottom portion of the screen. Then I notice the screen burn of both soft keys.
It went away overnight with the phone off, but came back by the end of the day. It's really upsetting as I love this phone, but hate having something that isn't working right. Any suggestions?
I've had the same issue a couple of times although it wasn't nearly the entire screen. It was just a small blob in the very center of the screen. It happened because it was in my pocket. When it occurred initially it was summer (30-40 degrees celcius here in Perth) and would fix itself after about 5 minutes of being in my hot car (temperature hot, not awesome hot =D ). However (more recently - it's colder now) it stayed for half a day or so and only fixed itself after I sat it in front of the cars heating vents with the heater on for about 10 minutes (not too hot). I'm wondering if the digitiser separates from the LCD when heat is applied. It makes sense to me but I'm not sure I'd recommend anyone trying my solution ... especially if you've got the big square issue.
You also have to be aware that this phenomenon is only visible under artificial light.
That's why some people report it to disappear/reappear.
True ... but when the "phenomenon" disappears (i.e. as the lcd seperates from digitiser) it makes a clicking noise and the screen behind the blob flickers (like when you push on a normal LCD with your finger) indicating that the pressure of the digitiser pulling the screen upwards has been released. Once this has happened the blob has gone. It's not visible under ANY light.
If it happens again ... I'll get some footage.
I found another thread regarding the "Oil Spot" that comes and goes on the LCD that I'm experiencing if others are interested:

Hi guys, I have the solution for you! I see burn-ins on my screen and I was able to get rid of them with a simple video that switches fast the main colors (Red Green Blue). Here is the link to the video:
http://www.youtube.com/watch?v=liMySLZkF5o
I have the video pulled from youtube as mp4, and 5 minutes of playing on full screen, the display got back to normal, clear and without any burn-ins.
If you need the mp4 vid, let me know so I can send it over (email)

Is there any way to check whether your screen has been replaced other than the obvious of taking it apart?
Reason I'm asking is because i bought a phone from kijiji and it was in immaculate condition and while it seems to be in great condition, the battery life is horrible.
I checked it thorougly before handing the money over, and like I said, immaculate condition.
One thing I did notice however in the morning when powering it on in my room in the dark, just a few seconds before the screen goes on, there are a couple of (what seem to be) blotches on the LCD screen and I wonder if it's not some kind of screen damage (ie - water maybe? or something along those lines). But it is screen related.
I have 5 months of warranty left (checked with the carrier, scanning ESN #).
Sounds like the screen has been damaged from what you have said. I would definitely send it back and get a new one since you are still within the warranty timeframe. I can't stand it when I notice something like that on my phone and it would bother me to not have it fixed. If you are sure that the screen is damaged in some way, then definitely send it back for a replacement.

You're right, I do plan on sending it in.
Was hoping one or a few of you could check your phones for me and look for something similar?
All you have to do is, power off your phone, go in a dark room, power the phone on and see if during the power up if any of you have any blotches under the glass on the LCD.
It shows up after the Darth Vader looking helmet logo in the Darkside Evo ROM, the screen goes grey but there's enough light inside to show the screen.
I'd really appreciate it if any of you could do this for me, plus it'd be good to know if I'm just a one off or if hours have this and have better battery life than I do... really wondering what's going on here.
I've decided to start a new thread to gain some focus on this issue.
It is common on the U11 according to some posts.
I've just noticed after the recent update, maybe it was there from the beginning, that this device has a lot of light bleed around the sides when using always-on feature. Some parts of the edges of the device has greater light bleed than other sections.
It's quite noticeable and adds more light to the room at night. If only the time was showing it would be perfect. This is what I thought was there before the upgrade. However I believe that any light bleeding is a hardware thing not a software thing.
This could be a reason why it drains the battery so much.
The light bleeding isn't noticeable during the day as far as I have checked.
Maybe I should return this device but not sure if HTC will agree.

According to some early buyer, U11+ shows the light bleeding only from the bottom right corner of the display.
Also it should be barely noticeable: if your unit has "lot of light bleed around the sides" maybe it has a faulty or not properly assembled display...or maybe you are exaggerating things!
Can you please show a picture of this issue?
In darkness, the light bleed is visible, and expected on an LCD because you can not light up just the pixels (the date and notification floating window) which you want to show on an LCD . The whole screen has to be lit up with minimal brightness.
In normal lighting, its not visible at all because the brightness on U11+ can go down quite a bit and blacks are blacker than I have seen on an LCD.
See attached image.
Not sure what's acceptable with light bleeding by HTC's standards or most mobile manufacturers.

Ouch! That really looks bad.
I was eyeing this phone, and can't decide between it and the LG V30. Both seem to be a lottery with the displays unfortunately...

Got my HTC u11 plus today and my screen has the same kind off light bleed.
It's only on the "smart display" though

Asia model , its very minimal on my phone. Have to stand in a dark room to see the bleed in the right hand corner
Mine is direct from Taiwan.
Yes, the bleed is only noticeable using the always-on feature.
I could swear I didn't notice it before the recent update. But it's got to be a hardware thing.
LCD Panel + Backlight = visible light on black screen. No surprises here tbh lol

Exactly!! To all the HTC detractors making this a huge issue, show me an LCD screen which does not have it.
Here is another nugget: the non-uniform light bleed shown in the photo above is because of special algorithm followed by always on display software. If you just do a full screen black (use the Full Screen Test from play store), you will see a uniform backlighting, which is the best I have seen on an LCD. U11+ display has no defects in my opinion.
HTC should not have even tried AOD on an LCD screen.
Htc m9 and 10 didn't have that much

I have the HTC 10. The black on HTC U11+ is blacker than the black on HTC 10 i.e. the backlight is even lower on U11+ than 10. I tested using the Full Screen Test I mentioned above. I would like to mention again that non-uniform light bleed is only an issue with always-on-display, and not with the screen in general. And its the non-uniformity of backlight that makes it seem like an issue.
Thanks for all the feedback.
I'm very happy with the U11+.
I just selected the option to turn the always-on feature when I move the device, so it's very liveable.
HTC has always been my favourite manufacturer for the last 13+years. The HD2 one of the best years ago.
Ouch, this light bleed seems harsh. Although it should be expected given the screen's technology.
It's not a default. Devsk explained it well, I wouldn't worry it
Even my Moto X Pure LCD screen has bleed, but it is only visible in total darkness on a black screen. Doesn't bother me in the least.
PS Anyone who is curious can download the Backlight Bleed Test app from the Playstore to view how much bleed your particular LCD screen has.
People who think this is normal for LCD screens, let me stop you right there! The HTC U11+ has blacks nearly as black as LED screens, even at night. There was no light bleed when I received this device. I held it next to the S8 Plus, and both had almost the same black values. It's amazing.
After a week however, I suddenly had an extreme light bleed, 0,5cm around all edges, like some sort of weird snow theme. Luckily it faded within an hour. Now it's normal again, except for the down right corner. That's only noticable when the screen is black, and it shows the time. It's barely noticable though.
This incident led me to believe it's anything but normal. The seller told me it's alright to exchange my device for a new one, so I hope it's not an issue with all devices. :fingers-crossed:
You'd think it's an hardware issue, but what are the possibilties the software influenced the backlight? Any thoughts?
UPDATE:
Just had a software update, and the light bleed is gone now. Even in the down right corner. Is this a coincidence, or do you think it might have been a software problem?

Hi guys, I've had the strangest thing with my U11+ yesterday. I picked it up and turned it on after it had not been used for just a few minutes. The display showed enormous light bleed!
All four corners had clearly noticeable white in them, and the sides were white as well. This was all with the screen turned on. It scared the hell out of me.
The white started disappearing slowly immediately. After 5 to 10 minutes the white was completely gone and my display has been just fine since.
Is this normal? How can this happen? Is my display history soon?
There is similar tread I think, and few people had that problem and me too once or twice few months ago but now everything is ok, except burns-in in corners, and while lines when it is cold, but I am waiting for cold weather to send phone back to repair or whatever. The display is disaster, it is impossible to show or look images on a sunny day...
Hi, the only threads I found were about the constant but hardly noticeable light bleed, especially at the bottom. Nothing about this temporary light bleed.
Good to hear I'm not the only one with this. I do not have white lines. I find the display very clear and sharp, it should only have been a lot brighter to use in sunlight.
Is anything known about people who send theirs for repair? Do they get it back with a brighter display?
I don't know if there is any help coz even u12+ has dimmed display.
They say U12+ is 10-20% brighter. Who knows.
Hey everyone,
Sorry if this issue has been discussed before. Couldn't find any similar issue for the A8 2018. I am having a bright, thin green line exactly at the middle of the display for a week now. Bought the phone five months ago, not a single drop, screen protector plus case, so I am quite sure there was no physical damage.
I tried booting the phone in safe mode and dialing *#0*# for the color test: green, red, blue as it might reset any stuck pixels to no avail. The line went away just once after turning off the display and back on.
It sucks if the screen needed to be replaced just after five months of usage. I lost my receipt as well. I was thinking that it might be a software issue and can be solved before sending it to Samsung for screen repair?
Does not sound like software issue sounds like you have a defective screen.
