[Q] screen visibility - Transformer TF300T Q&A, Help & Troubleshooting

Need some guidance, I have a Transformer 300 and having terrible visibility with screen. Screen Brightness is on 100% and have auto brightness turned off. Can view inside okay not great. Outside impossible even under shade. Only visible with complete darkness. Is this a hardware issue that I can fix? My eyes are starting to strain. I had to have screen replaced a few months ago. Could damage now be showing up?

Try an apk called Lux. It will over ride your tablets normal max screen brightness and Max it out to the device's true max. I use it on about 4 devices including my TF300T it's awesome

[Q] Adjusting brightness

Hi all,
Is there any way to reduce screen brightness even lower than what we could do with built-in settings? Thanks.

Wear sunglasses?
I'd love to know too. The screen is just a touch too bright in bed at night

I'd like to know this too, I have it at the lowest setting usually and it's still a little bright, I don't even need to turn it up outdoors.
On my modded galaxy s, the darky rom come with an app called "screen filter", it enable you to get your screen WAY dimmer, may be worth a look for in honeycomb, nice for froyo/gingerbread, you even have it in the task menu... my 0.02cents
I noticed that i always have to set it to the max cause it cut down on the glaze. This screen is like a mirror during the day.

try that app (requires root)
AdjBrightness doesn't work. I'm running Modaco ROM HR3, which means it's rooted, but AdjBrightness keeps saying it requires root. Thanks anyway.

Try "Brightness level" by curvefish. I can't guarantee it will work but it works on my g tablet?

I don't think any apps can make it dimmer, without rooting and system access. Brightness level widget doesnt make it any dimmer (it reports the brightness level as 8%, when the system brightness bar is all the way to the left, and when set to 0% in BLW the screen doesnt change).
One of the first things that I look for before buying any device is can the screen be set to a low enough brightness. Manufactures often overlook this in their quest to make screens as bright as possible, and in one case I ended up taping a piece of plastic over the screen of an Acer netbook as a filter to get the brightness down low enough to use in a dim room. In the case of the Transformer, I could not try before I bought, but the screen does go down pretty dim.
+1 for Screen Filter. I don't have a TF yet so I haven't tried it but it works great on my SGS and doesn't require root. I suspect it may not work as well on an LCD as on my SAMOLED screen on my phone since it doesn't actually reduce the backlight, but it's still worth a try.
Thanks, screen filter works!

Light Bleed

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.

Anyone have this auto brightness issue?

I noticed that my auto brightness will adjust and get bright when I turn on a light but then immediately when I turn the light off the brightness doesn't go back down. Anyone else have this? I'm guessing it's software?
Sent from my SM-G920V using XDA Free mobile app
Yes. I play with that by keeping my s6 under the lamp. Super high brightness levels.
I was just about to make this thread when I noticed yours.
Actually for me, I get low brightness levels it's very annoying. When I'm in moderate lighting conditions like normal lit room I get almost lowest brightness, when I move phone out in the open area, like outside, the screen lights up like it should, but in moderate lighting contitions it is very bothersome to have lowest brightness.
I'm now thinking of searching a good auto-brightness app. Any suggestions?

I cannot say any specific reproduction steps, but it looks like I have similar problems..
Galaxy S6 is my first Samsung device ever (before M9 I was HTC fan). Comparing experience with other devices I had - auto-brightness works definitely in a strange way.
Under direct lamp light - it's adjusted pretty much okay, but in a normally lit room - it's almost always too dark, and I need to adjust auto-brighntess level manually. So.. for me it's really not auto-brightness.
P.S. labas
So any other thoughts?

Same thing here. No solution so far. I tried to install velis from the play store, it is not working. I decided to return my edge emerald green ( ) because of this issue. In a normal lit room I get always low brightness, I have also the S6 flat to compare, side by side, and the S6 flat is almost at the same brightness if I set it at 50% and the edge at 100% (both in manual setting). Unbelievable!
I have S6 FLAT, and the autobrightness work ok if the phone are horizontal. But if i have the phone in my hand (in an angle more than 10 ° / 20 °) the auto brightnes bright the screen, but when i turn the light off the brightness doesnt back down. But if the phone are horizontal (0° in my hand or in a table, the brightnes bright up and down without problems)
There is a new 5.1.1 minor update available. Has this solved the brightness bug of the s6 edge by chance?

Just little different
I have a s6 flat and my screen is always on full brightness when auto brightness is on.
Tried the light senson and it seems to work fine (0 to 1 lux on dark room, 400 to 600 lux near to a light bulb). This problem started two days ago.

Same, here. Help us out guys.
auto brightness issue
I also got an auto brightness issue on my s6 flat version. Specifically it's about the adapting to low light conditions after being in high light e.g. turning on a bed lamp for a second (screen lights up) and after turning the lamp off s6 stays too bright and does not want to get back to low brightnes. The thing that helps is either lock/unlock the screen which makes it wake up with proper brightness or uncheck/ check the autobrightness box at the bar.
Is it commonly known issue that Samsung knows about or is there any possibility to get it back to normal on my own? It drives me crazy in a flagship device!

I have got the same problem and I'm dead sure it is a sortware issue. I tested the light sensor and it can update on different light conditions no matter the orientation is. I also installed Velis Auto Brightness app and it fixed the issues so Samsung should fix that since 3rd party apps can.
I too have the same issue. The brightness ramps up as its supposed to under bright light but doesnt go down under low light/no light unless i do one of the following:
1) keep my phone horizontal or at angle of >180 degrees
2) lock/unlock the phone by pressing the power button
3) manually tick/untick the auto-brightness check box
Really annoyed. I still under the return period so not really sure its a hardware defect or not
Well, unfortunately I'm facing the same problem :crying:
What are the differences to phones which do not have this issue repectively is there something in common who have this issue.
The biggest changes I've made to the phone are: Arrow Launcher (MS) and radiant theme (no root etc.)
I got the same problem, autobrightness adjust only when phone is placed horizontally. Any news in this regard?
unfortunately no
Do you still have this issue? Because I have it on every single ROM, Custom or Stock, no mather...
I have found the max_brightness adjustment, (sys/class/backlight/panel/max_brightness) but I can't find a similar file for minimum brightness. Anyone know it's location? At the moment I'm using a third party app as well, but would rather have the system fix.

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.

So what do you suggest? Warranty, hard reset or just learn to live with it. can update help you think?

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

That sucks. If the problem is physical it may degrade rapidly; a new display shouldn't have these symptoms.

if there is a bright point, you can see it for about 5 seconds on a gray background. the brighter the screen is, the clearer it is. after a while it disappears

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.

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.
