Light Bleed - Asus Transformer TF700

I know it's probably been addressed before but I was hoping for some kind of explanation to the lightbleed? on my TF700T. I question it because I ONLY notice it at the initial boot screen - when the "2nd" bootscreen comes (when the display dims), no bleed - Also, no bleed when on a black screen, watching movies, etc - nothing. Is the initial boot screen just set at an amazingly high backlight that absolutely any tablet (at least any TF700s) would experience this? Perhaps there is an alternate bootscreen I could install and test? I am rooted...
thanks for the advice
PS - I HIGHLY doubt anyone would return theirs for this

Do you mean the two spots on the right side, or do you mean bleeding out from other places? I have light bleed sometimes on the right side but it goes away after a minute or so. Like it has to "warm up" or something.

no, not really - at the initial boot screen, I notice it on all sides but mostly lower left around the "home" icons-when it appears - after the initial boot, it's pretty much gone - I am thinking that the boot up for some reason is set to such a ridiculously high brightness that 0 bleed (if it is even that) is impossible. Can you post a pic of yours during initial boot or a video?

I get lightbleed occasionally but it fades out after a few minuetes.

I think its normal.. my original prime had the light bleeds near home buttons too. I happened to have one of those from best buys first batch the sent in plastic no bubble wrap mailers so it had a dent on the box on the same side the light bleed was the strongest. But so far of the two inifinitys ive opened up at Best Buy, light bleed was in the exact same places.

The teardown from the Prime showed that it is caused by the screws holding the screen in being too tight. If you take it apart you can fix the light bleed spots by adjusting these screws.

I have the same lightbleed on a bottom of my screen (at 3-4 spots) going to the right side as well (1-2 spot). They all gone on the 2nd boot screen. Do you think that this will decrease the life of the screen?
Also I have notice something else and I really not sure what is causing this. I have setup brightness to about 30%, then If I start watching anything (Netfilx, YouTube or movie) my screen is start adjusting (change brightness up and down) like Auto Brightness options is checked, especially when it has a white (or very bright) background color. It is very annoying and very distracting for you eyes. Never happen on my Prime.
Does anyone have experienced the same problem? Any idea how to fix this are very much appreciated.
Thanks

Regarding your second issue that is a known "feature" called Dynamic Contrast.
Quoting the All in one Infinity Guide stickied in the General Forum:
[ Q ] My screen constantly adjusts brightness even if auto-brightness is disabled
Yes,that is a "feature" called Dynamic Contrast but not all of us like it.Follow the directions from this post to disable but keep in mind that your device must be rooted.

Thanks for clarification. I thought that something is wrong with the tablet. It is look like that I have to take the root solution.

I have what sounds like the exact same lightbleed locations. If I watch something late at night with all the lights off it is very apparent.
I don't think it decreases the life of the screen, my TF Prime had much less lightbleed, but it never expanded or anything.

[Q] screen disaster - random tinting, solarization, turns upside down

sooo, yeah. my wife has the t959v. the screen cracked months ago, replaced it with one from ebay, works fine. a few weeks ago, it was involved in an accident and needed yet another screen replacement; ergo, back to ebay i go. installed the new screen yesterday, turn it on, all is well. for a bit.
now, the phone isn't currently, nor has it ever been rooted; pure stock tmo us 2.3.6. during boot, the splash screens and boot animation are gorgeous and perfect in appearance. the recovery menu is exactly as expected. android boots as you'd want it to, and then the display will do one of the following:
-work properly (rare)
-automatically turn off, capacitive buttons still lit, touchscreen unresponsive - turning it "off" darkens the cap buttons, turning it back on flashes the screen on for a half-second, then off, with cap buttons still lit (common)
-graphical corruption ("solarized" colors, completely wrong colors, pixel vomit in essence) (fairly common)
-screen tinting, blue most often, followed by pale yellow, then greenish, then red (almost constant)
-screen inversion - the display will show as rotated 180 degrees; grabbing a framecap in ddms shows it right way up. touches are also inverse; you have to touch where the onscreen element would be if it were displayed properly instead of where the element is; e.g. a button on lower-left will display in the upper right, upsidedown, but the screen registers the button when you touch the lower-left portion of the screen. (quasi common, equally infuriating and hilarious)
none of these problems will show up in a screenshot at all.
i can reliably reproduce any of the above by simply adjusting the screen brightness. this will, quite literally, cycle through every possible defective display mode randomly for a split-second before moving on to a different one as long as you move the brightness slider.
MOST of these issues are transient and are either fixed (temporarily) or replaced with a different listed issue if you lock/unlock the display. it feels like a hardware issue what with the solarizing and color horrors, but is acting like a software issue, considering that recovery and boot are perfect and have never displayed any of these issues. i tried gently flexing and stressing the case in areas that might be a weak connection point, but can't get it to bug out that way.
in no way am i suggesting that i didn't screw something royally in the reconstruction stage, but i tore down and rebuilt that phone 4 times with identical results, so i can guarantee it's not some loose ribbon connector or zif socket.
i beg of you, great minds of xda, what the balls did i muck up this time? any hope for a fix? are there different panels, drivers, something?
thanks in advance
OK, if your screenshots appear normal, then your phone appears to be working correctly!
or at least it thinks it is we can conclude that it isn't the rom, kernel, or anything that you can blame the phone for going screwy.
Try buying another screen??
The ribbon connector might be broken?
yeah, these were what i figured what my options were. it just seems odd that the boot process and recovery menus have error-free displays while only the full android os doesnt. oh well, i'll probably just have to make a stink about it on ebay or something.
thanks for reading
You might try a fresh flash before getting a new screen to see if it is indeed a hardware issue. If you want to try that follow the second link in my signature. You will not need to flash bootloaders since you are currently on KJ6.

hell, warranty's void at this point anyway, right? may as well thanks much!
welp, all went well, screen was perfect through the whole heimdall/recovery process, but the problems still exist in the os c'est la vie. at least my wife's phone is finally rooted, i suppose. thanks anyway!
Have you tried opening it back up and reconnecting?
yup, 4 times, but i guess one more wont hurt
[edit]
it definitely seems to be related (if not related, exacerbated by) changes to screen brightness. turning off autobrightness has helped minimize the issue, but it still presents itself semi-often during screen-off/on events. obviously nothing useful in logcat.

That's interesting and could very well be a hardware problem with the screen. You wouldn't see that in recovery as the OS isn't loaded to mess with the brightness in that mode.
Does it do it on-demand if you mess with the brightness slider?

you better believe it does. rapid fire cycles through every color until it can't take it anymore and turns off. if i take/refresh a screenshot through ddms and poke blindly at the screen at that point, it'll still take input which is a curious, difficult game to say the least.

It's that Pink Floyd screen. You're supposed to drop acid & watch the wall when that's going on. LOL j/j
Given that you're on a fresh ROM & the problem persists, I'm leaning toward a hardware issue man. Sorry.

as fun as that sounds, unfortunately i bet i'll end up just getting my wife a used phone on ebay or somewhere similar and using this one as a development monkey. i was assuming that it wasn't something i could fix but hoping otherwise... yeah, that worked out
I just started having this problem. It wasn't too bad at first, just the color changes, but then it started not showing a screen at all. Changed to three different roms, even back to the stock non-rooted KJ6 and gave up. Keeping it on a steady brightness is the only way to minimize the color changing. I thought your thread had a solution but...
I may try opening it up and fixing the ribbon. But otherwise I'll keep using it as long as I can tolerate it until an S3 or a new Nexus.

nawp, nothing even close to a solution here i did end up buying my wife a whole new replacement phone and turned the broken one into my api10 development device. for what it's worth, yeah, autobrightness off does help a bit for when the phone is actively displaying content, but after you put it to sleep/screen off and try to turn it back on, it's a crapshoot. for a few horrifying hours, the screen was upsidedown even in recovery/boot animation and would NOT flip back to right-side-up until i ran the battery completely flat.
is no fun, 'tis truth. sorry for your troubles.

[Q] Defective display?

I don't really know what is happening but my year old nexus 5 seems to be developing a display problem.
It got a yellowish tint at the bottom of the screen but the top 3/4 is totally fine. What is causing it and is it just me who have this problem? Also, if you have any, please post some solutions to the problem without RMA or replacing anything.
It might be something about light leak but I am not seeing any when the screen is displaying a black picture.

I have a similar thing but it tends to only be on the bottom 1/8 of the screen.
I tend to find this is because this is the least used area of the screen - being where the soft keys go. Try running it full screen, full brightness on a white page (probably using something like this https://play.google.com/store/apps/details?id=com.gombosdev.displaytester&hl=en_GB). When you do this, does the yellowish tint fade over time?

By Over Time do you mean 30 minutes or a day? I tried this method before for about half an hour and it does not seems to be working. Will try it again now. But will it really help?
My OCD is killing me. I told myself not to look at the tint and I end up just staring at it.

[Q] Screen Issue? (XT926)

I received my XT926 as a refurb and I have been experiencing a strange screen issue.
I will often have my phone on a dock, charging and sometimes I will notice the screen is black like it's off, but the touchscreen is responsive. Hitting the power button does nothing but it makes the sound as if I had locked the phone. Hitting the power button a second time will turn the screen on like normal operation.
Very rarely I have noticed the screen will turn off while I'm actually using the phone and it's a weird effect. The easiest way to describe it is that it looks like entire lines disappearing randomly over a period of 1-2 seconds, going from all visible, then to all black, kind of like slatted blinds being closed, but at random. After this, it displays the same symptoms as if I had found the screen off while in a dock/charging.
Now, I don't want to say it's related, but I first started experiencing this on the Stock KitKat update from Verizon. I am currently using Cyanogenmod 12 nightlies and I am experiencing the same issue. It seems to be happening with greater frequency.
I have also experienced the blue screen effect when certain animations/elements/apps are up on my screen, but I think they are unrelated.
Also, there is a faint discoloration bar about 2/5ths of an inch thick uniformly vertically from top to bottom of my phone on the righthand side (just under where the notification bar would be if turned horizontal).
I've tried to find more information about this but my search results have been relatively lackluster (90% of the results are trying to sell me the phone or specification pages)
So I'm breaking down and turning to here. Does anyone know what's going on here? My current theory is that my screen is going bad. I have no intention of replacing the screen on this phone (would rather just buy a new one), so any suggestions that don't involve physical hardware repairs would be appreciated.
I thought i was the only one experiencing it.
The screen turning off with a weird effect happens rarely but yeah it happens. And the blue screen effect, i noticed it only happens when im on the youtube app when the video stops working because of my connectivity issues.
Im not rooted nor is my bootloader unlocked. On the latest system version. Sounds like a software problem but hey im no expert.

i also have this with my referb i made moto give me my money back and they let me keep the phone for me it was very rare but my new phone also had a really bad screen all yellowish and bad white balance in low light if you are unhappy with it call them and say you are unhappy with the replacement here is the white glove number 800-653-7185 they are more understanding and nice but you may lose you ability to unlock your bootloader on the new phone if it comes with the latest software just a warning
I have that screen off with lines slowly disappearing thing, too And, yeah, it's also a refurbished one, bought from one of the sellers on aliexpress... I thought Lollipop was the culprit or something like that. Oh, well... It rarely happens. And luckily I only have that, not the second issue you mentioned
I am having this exact same issue. The weird lines-to-black screen thing, and the flickering blue screen when watching video. Are you saying the solution is to call Motorola and ask for a new phone?
The blue flickering can be prevented by going into Developer Options and checking "Disable HW Overlays".
The discolored stripe on the screen sounds like burn-in; these AMOLED screens are much more susceptible to burn-in than the LCD screens used in older phones. Whomever owned the phone before it was returned to Motorola probably had something running on their screen continuously with a bright-colored bar at the top, likely in a car or desk dock. The screen is very easy to replace yourself with an eBay part, if you're inclined; it involves 2 screws and 2 connectors.
I've seen the lines-to-black thing exactly twice since I got this phone refurb two months ago. Sorry, I don't know what causes it or how to avoid it, but the workaround is quick and simple enough that I'm not worried about it, yet.

X2 Pro Screen burn?

I'm using CN X2 Pro, 2 weeks old. I noticed that I get 1-2 seconds of ghosting/screen burn from the always on display when I unlock the phone. I still see the dark numbers on my light background. This fades after 1-2 seconds but I've never noticed this on other phones with AoD's? Do you think it's a sign my display might suffer in the future?
I have the same issue with AOD turn on, there is a ghost effect and disappear after few second. I found if you choose dimmer clock color, there is no issue. So, try switch to different clock style, try avoid those white color clock.
Hi. I have the same problem. What do you do guys? Other light spot and the same trouble
Hello. I think its's because of AMOLED screen.
I started getting it with AOD after updating to Android/ColorOS 11.
Previously, the AOD would move around the screen so it didn't happen.
I've had to turn off AOD because of this.
And what do you do? Send to service or something?

Interesting. Yes, prolonged static displays should be avoided.
AMOLED screens do not suffer from burn in. They degrade over time from usage.
They have a long but finite life span.
High screen intensity is the biggest degradation accelerant plus time. High heat ie sunlight should be avoided when possible.
The highest energy blue pixels burn out first, lowest energy red pixels last.
Damage shouldn't be observable in a screen so new. These screens are rated for thousands of hours.
The ghosting may be a firmware glitch and nothing more.
Avoid using over 50% intensity except when needed.
Don't use in direct sunlight except briefly.
Make use of black wallpapers and dark mode as much as possible. Whites and blues should cause the most damage. Reds the least.

A hard reset will do nothing but waste your time and patience.
If you really have damaged pixels, warranty as the display is likely defective.
If it's not actual physical damage only a firmware update can fix it. It may take months or never come at all. So again, I send it back either to be fixed, replaced with a new unit or a 100% cash refund. Nothing less.
Use screen testing app like this one:
Display Tester – Apps on Google Play
Test your screen and figure out whether it has hassles.
play.google.com
I use Screen Test but can't pull up a link. Playstore may have pulled it... as usual.
I guess I will only send the problem is that I bought it abroad and it will probably take two months

Question about screen dimming

hey guys got question for u all
i like so much the flip 4 but i sell it cause i had 1 major proble
i bought iphone 14 pro max but i really want my flip 4 again
my problem is any time im using the phone for facebook whatsapp and regular stuff with regular use (not even hard use at all)
the screen dimm to much cause the phone is warm
if i turn on the extra brightness its dimm alot faster with minimum use
so i i never used the extra brightness but always on the full brightness but i always use minimum use and the screen is dimm
any solution or its like that???? (the phone is ok i had 1 before and it was the same)
i have no case nothing i never pleyed games with my phone just regular use....any tips for what to do or this is how the phone act?
and just for you know im on android 13 latest thx for the help !!!
sounds like you have some sort battery saver turned on, have you checked in settings? this is not normal behaviour.

im using whatsapp facebook instagram and messanger maybe? anyone knows?
On the Flip 4 I use the Adaptive Brightness "on" setting, and Dark Mode. Your results may vary, but here's what I've seen.
In the summer, on a sunny day, I'll notice that the phone will automatically try to be as bright as possible, so the screen is readable. (I'm pretty sure when this happens the quick display panel's screen brightness slider color changes to orange. Maybe the color depends on the wallpaper/color palette.) And I never see the screen do this "extra bright" thing indoors. Only outside and only in direct sunshine.
So far so good. I think this is as everyone expects the phone to operate.
Given all this, sometimes I'll notice the screen brightness will vary, even though I'm still outside and still in the same brilliant sunshine. I've noticed this commonly when checking Google News, and for example, I'm reading a story and scrolling slowly through the article. In particular when the screen is mostly black text on a white background.
So, in this situation, that is, a largely bright background, in the bright sun, my phone will both:
Get warm to the touch, on the back-side of the phone, where the two batteries are, but not up where the cameras, CPU and memory are located. This makes sense because "scrolling text" isn't that demanding on the CPU, but I am driving the OLED screen hard.
Also the front of the phone (the OLED screen itself) can feel warm. Even in the screen's crease, away from the battery. Since the image is mostly white, all the OLED dots are "on" and give off heat. Then again, I'm in brilliant sunshine and almost any surface will get warm.
Further, I'll notice that the phone screen will automatically get dimmer after a bit of time (perhaps a minute or two of extra-bright before the dimming). This I attribute to the software doing one, or both of:
Dialing back the screen brightness, to prevent OLED burn-in.
Dialing down the power usage by the screen, to prolong battery life and/or limit the battery temperature.
What's more, after little more time, still in the same bright lighting conditions, perhaps reading the same story, the screen might be noticeably extra-bright again. It's as if the phone has given the display "a rest" and is willing to go "extra bright" again.
In short, I think the phone screen is trying hard to be brilliant in the brightest of sunshine. But there are limits in how hard you can drive an OLED screen, and how long the battery can power the screen.
All of this before we start to talk about what design limits come into effect when the CPU or graphics processing come into play, both or which compete for:
Power from the battery, and
The ability of the phone to keep itself cool.
This phone's form-factor is all about folding in half. A slab form-factor phone, I suspect, will be far more capable for heavy CPU, graphics, and provide a bigger battery and better heat disipation.
