[Q] MT4GS lcd brightness levels

Hi guys! I need to confirm something if this is just an issue of my phone or this is just it on all MT4GS devices.
When manually adjusting lcd brightness does anybody notice that brightness levels past middle seems the same? I mean when I adjust the brightness level on settings and when it's past the middle level the brightness doesn't seem to increase anymore. It's just very noticeable on the first 3 levels. Hope anybody here could give some feedback.

On mine the increase or decrease past the middle is subtle but it does make a difference. Whether you can notice it depends on your ambient lighting.

Really? I'm pretty sure mine doesn't really adjust it's brightness... And I tried every ROM I can get even stock and still the same. Would love to have feedback on some users also from this. Maybe it's with the LCD type. If I can confirm that this is a software problem then I will really be increasing the brightness level by modding it.

I checked again in different lighting... a dim room, a brightly-lit bathroom, and outdoors in daylight. I could not tell any difference outdoors or in the bathroom, but in normal lighting and more so in the dim room, it was very obvious that there was change past the middle. This is using the Miktouch 0.7 rom with standard kernel.

Ok I'm gonna try it in a dim room later. If it doesn't change only means I got a broken hardware :/ BTW I'm using a full stock ROM when doing this.

Im on pacman rom and my brightness adjusts past halfway

Ok confirmed I got a broken brightness level... lol dunno how this can happen but the level works only up to 1/8 of the full scroller in the brightness setting. Any adjustments past that won't work anymore.
tried it in stock rom, miktouch rom, sense 4.0 rom and CM9 ROM results are the same. So lame I just noticed this when I used my phone from a very bright sunny day and the screen is barely noticeable.

On mine, when moving past the middle there seems to be just two minor alterations, at the 3/4 mark and the full mark. I can notice them when I'm in normal room light and more so in dim light.

It could be that automatic brightness is turned on overriding the manual setting, depending on what rom you are running.

Nope can't be possible... The setting is working but not fully. I can adjust brightness only up to the 1/8 level of the scroller past that brightness does not change anymore.

[Q] Galaxy Note Edge Tmobile. Brightness Issue/Overheating

Just got my Note Edge 2 days ago and when comparing the screen brightness (at max/no auto) it is much dimmer than our note 4. now I am not talking about the super bright setting that occurs when its on auto and outside but instead indoors. I also have been seeing a message in the display brightness settings "UNABLE TO INCREASE THE BRIGHTNESS FURTHER. THE DEVICE IS OVERHEATING" Could this be due to a faulty battery or something else? This is my only complaint with this phone but its a big one especially if i'm receiving this message. Should I return to Tmobile or is it most likely a software glitch. It is very cold where I am at so it has not been out in the sun or plugged in too long. minor use has led to this overheating message usually only seen in the summertime when in the car too long

why you need turn on full brightness? I only use brightness like 20% on that slider. it also save battery.
Sent from my SM-N915T using XDA Free mobile app

I typically enjoy and have always used max brightness and even if i didn't this issue probably shouldn't be happening. It's the fact that i think something is wrong with my new phone already. I want to make sure by asking questions

Yes something is wrong if you're not gaming intensely or something like that. It should never overheat just from full brightness I have the T-Mobile one and I use max brightness all day no problems.

Guys the samsung NoteEdge on lollipop has that issue. Basically you can't switch auto brightness fully off it will control your brightness even if uncheck the box. After weeks of searching and trying I found a kind of solution because I love to see my screen in all his power and brightness. Solution is call "screen filter" can be found in the play store for free. Set the brightness at 100% and switch it on. You'll see the difference.

Should i worry about screen burn-in on my Oneplus 7 Pro?

Hello, I've recently purchased a Oneplus 7 Pro and noticed it was using an OLED panel, the problem is that Burn-ins scare me a whole lot, as such, I have been wondering how others have been using their phones. I've tried using Google, but have found nothing truly satisfactory and as such, I have compilled a few questions i had about the display.
- Is screen burn-in still a real issue? and should I avoid using the phone over long periods of time?
- Do "True black" wallpapers help with this issue? what about dark gray? and a bright wallpaper?
- Do both the static navigation bar and status bar have issues? Same with the AOD, does the fingerprint icon cause issues?
- Should I take extra steps to prevent burn-in? (If so, please say which ones, eg. Any practices you have to prevent screen burn-ins)
(On a side note, does anyone approximatly know how long [in general] an OLED panel at medium brightness and daily moderate to heavy use has before it shows signs of burn-in?)
I'm sorry if this has already been addressed, but i have searched through the forums and have found nothing.
Thanks a lot!

I don't even think about it.

I share the same concerns.
The last OLED phone I had was a Galaxy Nexus and I told myself I'd never get an OLED screen again after that nightmare.
Dealing with the OLED issues has been better with improvements in the technology and overall quality control.
Android OS also has some changes that help prevent burn in. For example the navigation bar and status bar change colors based on the app.
With AOD I know Samsung for example slowly moves the elements around so it doesn't burn in. You can enable the Oneplus AOD with root but Always on Display isn't the same as the Ambient Display on stock Oneplus. Ambient display doesn't stay on screen long enough to really cause any burn in.
Best practices are to avoid high brightness, stay at half or less. If you have a game HUD or other static elements on screen for extended periods of time, rotate the phone when in landscape so it is less likely to burn in.
I'm not an expert on this so i'd like to hear others responses too. This is a more expensive flagship phone so I want to use it for games but avoid the burn in.

I've already read some reports of burn-in on Oneplus Chinese board. The culprits seem to be some Tencent games and its video streaming service. All have very high contrast UI elements, and users tend to turn the brightness very high.
This was the case with my plasma TV. Civ4 left some nasty burn-in in the first year but after so many years of heavy PC usage those remain the only true burn-ins on the TV. It depends on the app. Are there some ways to measure contrast of onscreen elements? In addition to phones I need to replace my plasma with OLED in the coming years.

I got burn in on my OnePlus 3 bc I keep it in my car and use it for a music player, there were times I left it on overnight on a static image multiple times, so if u plan keeping ur phone on all the time on a certain image then u don't have anything to worry about.

I used the Galaxy S3, Oneplus 3, Oneplus 5T all with OLEDs. No burn in. Never. Of course if you are and extrem case and you leave the screen static on for a lot of hours on several days there MIGHT be the risk. But with normal to "normal" heavy usage you shouldnt really be concerned.

Better u only turn it on for a few seconds, be carefull after 10 sec it gets critical..

Just don't leave the screen on at max brightness for long periods of time and you'll avoid burn in.

Because the pixels are self-illuminating and will eventually wear out/start dimming in an OLED display over time, this will probably be a concern with any phone that has such a display.
I had burn-in with my OnePlus 3T starting after a little over a year of use. I had my 6T for about 7 months and hadn't noticed any problems with it by that point.
I think the biggest culprit in long-term use is the notifications area of the status bar, unfortunately. The notification icons usually directly contrast with whatever is on the screen at the time, which ends up causing the pixels to wear out at different rates. While the burn-in on my 3T wasn't defined or crisp, there was a noticeable brightness difference where the icons usually display, and it was apparent any time there was a solid color in that area of the screen.

To fight this, keep up to date with swiping away notifications, and use gesture controls in OOS instead of the navigation bar.

Use Auto brightness and enjoy the phone...

Honestly, I would be concerned. I have noticed screen burn on my 7 Pro already. My specific case is that I use Waze while driving, and on long (> 1 hour) drives I get the UI lightly burned in. After I noticed it, I alternate the phone orientation 180 degrees to minimize its effects. I also have the "Colors" screen saver activate whenever plugged in, which has noticeably reduced & corrected the issue. Just be aware and adjust the phone orientation regularly and you should not see anything burn in.
My Galaxy S4 and 1+ 3T both had burn in, but after several years of use. (Same app was the culprit.) I think the reason it happened on my 7 Pro faster is because of the higher brightness and 90Hz refresh rate. Once I kicked it down to 60Hz it does not happen near as often .

Do you have your screen turned to full brightness when using waze? I keep mine at about 40-50% brightness. I use maps for 2-3 hours a day 4 or 5 days a week and I have had my 7 Pro since launch and I have zero burn in. I have never had burn in going back to my note 3 days either. I/m actually looking at my OP6 right now as well and no burn in there either (bought that on launch day as well). I also activated forced 90hz all apps on my 7Pro as well and nothing yet. I'm guessing it's your screen brightness that is doing it. Nothing else makes any sense.

Tmobile demo both phone in my store have burn in.... But also does the note 9 and a few others.

Those have the same image on the screen 90% of the time and the screens are set to max brightness to show off the display. All AMOLED displays will burn in if you test your phone the same. When I use maps, I turn off auto brightness and just set it bright enough to see the screen which usually is about 40% brightness. I also change my wallpaper like once a week as well

Had burn in on both 6p and s9 and all in status bar and navigation bar. Now I've installed system tuner and switched on full immersive mode. You need to be rooted though. Using battery widget to look at battery life.

Used my OP3 for 3 years straight until I switched to the 7 pro. Never had to think about burn in. Just chill and enjoy the device

When using google maps or waze on long trips, keep the screen off till the next turn. That's what i do. I NEVER keep the screen on long enough with a static image. I don't think there is any tech that will not give a burn in with a static image over long periods of time. I will still pick OLED over LCD any day.

Everyone should just have a spare lcd phone for navigation. I use an iphone 6s for navigation in my card. Tether data from my phone and dont have tk worry about burn in

I use mine for navigation ,i drive a convertible so the screen is always on high brightness.
Never had any issues with my galaxy s8 which i had for over a year and used it the same way. Poor thing had the maps on more than anything else.i broke the display before the any burn ins.
The display should not have any burn ins even after prolonged use.
However you might want to keep it at 90%max brightness.
I make the most of my oneplus 7 pro so if i notice any burn ins i'll just return it to warranty. I don't care ,i use the phone however i want to.
Also the colors are going to be visibly washed out after a few years of use compared to when it was new,that's why i always insure my phones and just get a brand new one before my contract expires.

In order to avoid getting burn-in you have to:
1. Avoid displaying images with static contents for more than one hour at a time. Many people get their keyboard burnt in because they text obsessively.
2. Avoid using a higher brightness than you need.
3. Maybe use the gesture based navigation.
Tipically burn in is a non-issue but displaying static content for more than an hour uninterrupted can get it to appear, depends on the panel, brightness and color being displayed.. Just pause what you're doing every once in a while and you should be fine.

Colors looks like rainbow/greenish on the lowest brightness

Hey guys, when I lower the brightness to the lowest, the screen looks so weird, everything is washed out, and the left side is less bright. And also more I lower the brightness, grey colors look more greenish. Changing 120hz to 60hz makes a big difference but my question is, is it how the note 20 ultra's display works? Does your display look fine, guys? Should I get it replaced?
Here is the picture of the difference between normal and low brightness: https://imgur.com/a/NubU2ER

i had this big on 3 different tab s6. it is some kind of software-bug, cause this issue does not appear while the device was booting. BUT since you cannot do **** about this (even reseting wont help. some kind of firmware issue) your only option is to get replacement. thats a known issue for amoled-displays (but its also known that if you dimm the display enought, green is the last colour that you will see on the display)

Question How to fix pwm on this device?

It has pwm even on full brightness. I tried the pwmfree app https://forum.xda-developers.com/t/app-amoled-pwmfree.3898070/ but it still hasn't fixed the problem.
Doesn't it bother you? My eyes hurt while looking at the screen.

I've read a bit about it on the link you've provided. How did you know if our phones have it? I am quite interested in this!

You use the camera from another smartphone or another device to look at the screen of the a52. And you change the shutter speed or exposure in the camera until you will see the bars pulsating on the screen of the a52.

Oh well then it seems like most of my phones since 2015 or so have had that, and I've never really suffered from headaches from it, not that I've noticed.

You can't notice it consciously, but some people, including me, are affected by it. The thing is this could easily fixed by samsung, but they wont do it. Other companies have removed the pwm effects on their amoled screens.

Damn that sucks, especially when you know its an easy fix from the OEM to implement.
One thing though, from what I've read off the PWM Free apk page, it uses a transparent black overlay and increases its opacity as you decrease brightness. If that's the case then you could use Twilight to acheive the same goal, right? Just max out the brightness and turn off auto brightness, then use Twilight as your brightness adjuster, turning the bluelight option down. Could that work?

The weird thing about the a52 is that it has pwm even on max brightness, so probably twilight wont work as well. I will try it later though. Same problem on the premium samsung range: https://eu.community.samsung.com/t5...been-addressed-on-the-s21-series/td-p/2641628

Yeah, it still flickers even at full brightness. Maybe setting it at 60hz could fix that? I'll try it later to see if that could work. My previous phone doesn't have that issue at full brightness, so I'll gauge the difference based on the difference between the two.

I use mine only on 60hz and it still flickers.

Yeah, I've tested it and there is a difference between 60hz and 90hz, but the flicker is still present.
Edit: I also re did the test on my old device, a J7 Pro, and it stops to flicker altogether at peak brightness. So yeah, this phone has very prominent PWM.

Yeah, that's why samsung should do something about it. Because we still have flickering at max brightness, we can't use other software to correct the issue.

I suspect you didn't actually have the brightness set to maximum. This cannot be set manually, but is only set when the ambient brightness sensor (front camera) is illuminated by a very bright light - the sun, or a very bright flashlight. The brightness of the display is then visibly increased above the normal maximum.

Well, if the max brightness can't be controlled then it's not relevant. In this review https://www.notebookcheck.net/Samsu...ntly-more-affordable-without-5G.539956.0.html they tested the pwm on the display with an osciloscope and it shows that when you manually set the display at 100% brightness it still has pwm. This is one of the worst pwm out there, and a shame for samsung to do something like this.

is a shame unless samsung make a change in the firmaware the a52 is a pain in the eyes i need to sell mine now i cant play any video game unless i want a eyestrain

Pwm sensitive here.
Samsung A71 was OK pwm 240 hz.
Samsung 21fe was OK pwm 240 hz.
Samsung s6 edge was OK pwm 240hz
Mi 11 ultra not OK pwm 480hz. Not OK even with anti-flickering or pwm_free / oledsaver app. Mi 11 ultra has Samsung display E4.
I really don't understand. Maybe is the highs and Bottoms in the amplitudes.

Works well on my galaxy s8

Hi. I realised the negative effects last year after a year of using amoled display on redmi note 10. It gave me headaches and also my eye power changed from 0.5 to 1.5 for both the eyes in just less than a year. I do 3 hours of use a day. That's how I learnt about PWM and the headache it gives to people.
edit - REDMI NOTE 10 died a week ago and I am searching for a phone which doesn't have PWM issue in it. For past 7 days I am using LCD screen and my eyes feels a lot better.
