All apps are show notch, running granular immersive mode. Still bar above. - Huawei Mate 20 X Questions & Answers

So i just got the phone last night and i applied both to try and force any and all apps to show notch so i can enjoy all of my screen. Idc how i have to do it but for whatever reason when i open certain apps, they still overlay a gray, white, black, empy bar where my notifications would normally go and its very frustrating.
I gave granular permission, put full screen on every app and even told every app to show the notch... Is there any other way to bypass this issue so i can get any app regardless if it likes the aspect or not to show the notch and remove this bar?

Could still use help with this https://cdn.discordapp.com/attachments/471469010672812033/544203189558181900/Screenshot_20190210_120903_com.facebook.katana.jpg

Are just some examples. White bar is where it should show the app and if it were digital, my notch

I have this problem with certain apps even forcing show notch just turns in showing a white bar instead of black in landscape.
I don't think there's something we can do about it atm, I guess it's more of an app incompatibilities with notch since it works perfectly with some apps and not the others. Not sure if it's on Huawei or Dev's app side.
When it doesn't work It's better to let it black than white for your screen.

Thankfully I'm glad I'm not the only one and it's not just a me problem. Thing is. IDK how to force a certain color up above. Like for example if I use Nova to swipe up as search, it will just put a white bar up there... And you can see someone else is doing it cause for a split millisecond it shows the operation as intended with just the search box. Quickly after though it sticks that bar. Same thing with for example Sao internal factor (game)
When you start up the game it'll give you the entire screen, but soon as you check your mail or news and close them, the white line takes over where the notch is. Very frustrating and I feel like it's in the system, not the game... But who knows I could be wrong
I just hope a mod or fix is made soon because if I had know I would not be able to take advantage my entire screen, I would never have bought the phone

[Q] Note 2 screen problem?

I bought my phone from an online store in Romania on February 22.I have warranty and other things, it was brand new. I kept the screen on full brightness, and Dynamic color mode. That's how I like it. I was aware of burn in so I switched colors with a display tester every 3 days or so. Yesterday I noticed that the spot where status bar is used to be in portrait mode is brighter than the rest of the screen when displaying blue, white and grey colors. Brighter not Darker. I searched on Google images and that doesn't look like burn in. It wasn't here until yesterday when I spotted it. It's barely visible with display tester but in Games videos photos and multi colored things it can't be finded, You need to look with max attention. I used Nova launcher to hide the status bar. I also heard that there are 2 different things, image retention which is fixable and permanent burn in. I searched for something like this but I don't seemed to find something good. I don't know what it is,I never browsed the Web without changing the pixels where the status bar is for more than 20 minutes. I heard burn in occurs in extreme cases. I don't know how this happened so that's why I'm asking you guys. I don't know even what to do it bothers me only in display tester, but otherwise the screen is perfect. Please give me an advice because I don't want to have a faulty screen.. Can it even be repaired under warranty for that?
No one knows what's the problem?
Maybe you could post a photo ?
Look at the top of the screen...That's actually what I'm seeing when looking on a blue test background.This kind of discoloration/brightness where the notification bar usually is when in portrait mode.This is not a screenshot or photo ,it's just a blue image that i modified to show about i'm talking about.It also happens on grey and white and cyan .I couldn't take a photo because i have a crap 7 MP shooter ,and one crapper 2 MP shooter on my old Galaxy Y.I tried them both but noone of them can catch thatstrange discoloration/burn-in/brightness
Xda don't let me to post links..That's the link without the X'es so delete X from this link to go to the image hXttp://i4XX4.tinypic.coXXm/2w4g39j.jpgX
I really don't know what this can be.
I have the same problem! I noticed it a few weeks ago. The bar on top, when in full screen mode, is slightly brighter/lighter compared to the rest of the screen. I can see it the most when using the browser. The screen looks slightly more yellow compared to the grayer (or something like that) bar. Remember the bar is not actually there, just the discoloration in its place. I have no idea what is causing this and I'm hoping it's not hardware related.
It ain't hardware if it shows up in a screenshot. Looks like the exact dimensions of the status bar, almost as if it's compositing it or it's shadow placeholder where it expects it to be. Try a different ROM, or install the Simplistic Framework and try changing the status bar's colour and transparency setting, see if it makes any difference.

I wrote that.It doesn't show up in screenshots.I edited a blue picture to look exactly like my phone screen.The problem I think it's the screen itself.And the reason for why I edited a picture is that as I said my shooters can't spot it.Any ideas?Also I use the stock ROM ,un-rooted..Everything stock ,including the notification bar.I just have a custom launcher wallpaper and widgets...
It shows up when you turn the phone in landscape mode as well. It remains on the side as a vertical discoloration where the notification bar resides when in portrait mode. I'm not pleased to say the least.

Exactly what's happening to me.
Made in china phones r crap..made in korea by samsung is gud quality
If you have the warranty the warranty, why not use it? Since the problem is from the phone itself.
This is same like what happen to OG note..i thought sammy already solve the problem when they using RGB instead of pentile on our note 2.. this is not good...
I check mine, so far nothing yet. But i afraid now!!

I also thinked that it won't happen on Note 2 too ,but here it is.I'll go further and I'll send it in the service ,after my holiday ends.This thread is good to maintain active because it may help people that also came along this problem
I always set brignest to auto and screen movie mode. So maybe it did save mine from that problem

My phone was on Dynamic and Full Brightness all the time.I love oversaturated and bright screens.LOVE AMOLED <3
Well I found a solution to the problem. It takes time to pull off and is still a work in progress for me but it's working.
I created an image that matched the resolution of the phone screen. I then made a rectangle at the top of this image that presents the exact size of the status bar and colored it white. The rest of the image was colored black.
I installed an app that keeps the screen on without dimming when plugged into the charger. Overnight I display the image I created with the screen set to stay awake and don't dim at full brightness. So what you see is a black screen with a full brightness white strip where the status bar is supposed to be.
This process quickly "ages" the status bar area and it slowly starts to match the rest of the screen. I've been doing it for almost a week and the difference between the two sections of the screen is starting to diminish. I bet a couple more weeks of this and the difference between the two sections will be gone.
I got the problem as well. And I'm telling as many people as I can because I'm annoying like that. Seriously, I hate the fact that I spent such money on faulty phone...Samsung galaxy note 2. <blech>
Unfortunately, Camera has stopped.

Is there a way to force apps to run full screen without the black bar at the bottom?

As mention in the title, I have been looking for a way to get apps to take advantage of the entire screen. Most games (Hearthstone, Cosmic Express, etc.) have a black bar at the bottom even when immersive mode is active. I have used apps such as Granular and Nav Bar Hidder to force immersive mode which does work for some apps but not for every app.
Other android phones such as the LG V30 and the Samsung S8/Note 8 have a feature where they force apps to run full screen with no black bar. I know custom ROMs could fix this problem by porting the feature and I have been looking around a ROM that has this feature, with no luck.
Does anyone know of a fix or a ROM that could help?
I think the apps need to be updated to take advantage of the 18:9 screen.
That's how it looks.

I measured it, the navigation bar hight is 168 pixels and the black area hight 202 pixels. So I would say on the unfilled area, the developers are to blame because they have not optimized the apps for 2:1 screens.

Funny thing is that this phone doesnt auto centered the screen when using an app that havent optimised for 2:1 aspect ratio,
Example, game will use left area of the screen, leave a big black unused space on the right.
Sometimes the "stock" thing in pixel make the phone actually dumber,
My S8 do better handling this situation.

I agree samsung's solution is better for this issue, should have been common sense by google to do the same.
Honestly the aspect ratio is the only thing that really pisses me off about the screen. Colors, tint, blah blah blah...I don't care about. The fact that many app developers still haven't gotten off their asses to fix this aggravates me to no end. I'd much rather have the 5.5" screen of the Pixel XL in a supported format then a larger device with a 6" screen that triggers my OCD.

Random blue light over navigation bar

this might be a weird problem or question, but I have this random blue light flashing slowly over navigation bar when I'm on a game in landscape screen, such as Heir of Light or Mobile Legend. I use the hidden navigation bar type instead the one that taking extra space. I wonder if it's coming from 3rd party AoD I used before, such as Notification Light or Always on Edge, but I have them both uninstalled already, I wonder if it's coming from them because previously I never saw this blue light over my navigation bar. I noticed several things about this light:
This light appears few seconds after I opened a game that is on landscape mode which hides the navigation bar. The light will flow surrounding the navigation bar area for around 2 times then it will disappear completely.
It only appears once on every restart, so if I open the same game later, it won't show until I restart my phone and open the game again.
I've tried to see if it comes in other app so I tried on Whatsapp and Firefox browser on landscape mode but the light didn't show up at all
I'm concerned with the battery this light consumes so I also checked what's running my battery life but I didn't find any unusual app running or hard-consuming my battery
Does anyone have any idea what this light is? or anyone else having this problem? What I want to know is where this light is coming from and is there any way to turn it off? because I really don't like unnecessary app consumes by battery...
I have attached a screenshot about how it looks like, any kind of help would be appreciated.. thanks in advance
SOLVED:
Thanks to chirogan that mentioned this is actually coming from the Game Booster feature
chirogan said:
Do you want to disable it?
While playing a game, make the navigation bar appear and youll see a game booster icon in the lower left corner. Click on it and youll see monitoring temperature and memory icon. Click on it. Then click on Auto Control and disable it. Youll notice that the blue light will be gone because it doesnt optimize your apps anymore.

It's a possibility.. but this light doesnt just show on any app.. it only appears on games that take landscape and full screen that force hide the navigation bar.. I tried to see if it appears on YouTube app but it didnt.. it also doesnt show on portrait games.. im wondering if this has something with Game Tools or Game Booster or anything that triggers when the user plays games on full screen to let them know 'where' the navigation bar is but not sure yet Beside, if it's from firmware, I expect to already see this light from the latest OTA I got on September, instead I only noticed this light few days ago when I also happened to try some 3rd party AoD apps, which also I uninstalled immediately after play around and checking out how they look

Have you rebooted your phone after uninstalling those apps?
Look for a app called "Game Launcher" it may have some settings ticked to do that.

I am using some of GoodLock apps I got from https://forum.xda-developers.com/galaxy-a70/themes/appssamsung-goodlock-2019-pie-apps-t3958121 , but not all of them. only these:
LockStar - for Lockscreen style
NiceShot - for Screen recording
QuickStar - for Status bar and Notification style
ClockFace - for custom clock on lockscreen
I also got One Hand Operation+ but it's from Galaxy Store. I could understand if I have some GoodLock apps for navigation bar, but I didnt install NavStar or any 3rd party app for navigation bar since I dont use the "button" style at all because it's taking more space of my screen

Its not a bug. Its an application called Game Booster.
What Game booster does is to control and monitor the Temperature and Memory. Once it detects that the application is heating or consuming too much memory, it optimized the phone by closing apps, adjusting brightness and other things that god only knows what. This is to prevent your app from over heating and forcr closing due to memory issues. Once optimization occurs, thats when the blue light over the navigation bar appears. In theory, it does the opposite of what you think. It optimizes the phone in such a way that it prevents abnormal usage in battery and memory to give the best experience in gaming. But sometimes it compromises the app by throtthling the game when it needs a boost in CPU and GPU. It depends on the application on when youd like to activate or disable this feature.
Do you want to disable it?

Edit: out of topic question. Do you experience frame drops in mobile legends? Especially when switching from one app then back to mobile legends?

Thanks for this.. it's just as u said, the blue light is coming from the Temperature Control, once I toggled the auto control on/off the blue light is there.. now that u mentioned it I remember I recently updated Game Booster few days back.. Now I know where the light is coming from.. Thanks again.. :fingers-crossed:
I used to get lot of Frame Drop few weeks ago after this latest update with the "new form of spells", I could barely play anything.. but I didn't do anything tbh and just keep playing until now, and it's way better now. There is still some Frame Drops but it's only when super heavy stuff going on at once in the game, compared to the first time I experienced it, it's so light now even tho I didn't try to do anything to fix it.

Thanks for the confirmation too. I used to have a lot of frame drops but it was due to Game Booster and Game Optimizing Service not working well. After the update, it improved the performance significantly but there was only one bug left. It was when switching from the Game to another app, then going back to the game, it causes the game to start frame Dropping.
Hopefully it makes the update better on the coming days.

S20 OLED image persistence

Is image persistence normal for S20's screen or OLED screens in general?
For example, playing a bright video game with black aspect ratio bars, leaves a lasting persistent image, where on dark pastel backgrounds you can clearly see where bars and game were.
Or writing a long article, leaves remnants of Android's nav. buttons, Chrome's address bar, and even keyboard visible, when tested on dark pastel backgrounds.
These persistent images gradually disappear, but it takes a long time to disappear completely. Do you experience something similar to this?
Thanks.
Scroll down for testing methods, post #5. Start by opening dark gray image, view full image, zoom in, do you see discoloration?
Image retention (persistence) is a somewhat common issue with all OLED. That said you shouldn't be experiencing it unless your constantly rocking your screen at 100% brightness, or near there, for hours on end.
I found this cNet article which explains it really well.

The Galaxy S7 and S8 had issues with Screen Burn which Samsung improved going forward from the S9. If the ghost images gradually disappear it isn't Screen Burn which causes permanent discoloration. If under warranty you may wish to get the device replaced, it doesn't seem the problem will correct itself over time. The other options I would consider are uninstalling apps which you enabled just before the problem appeared or performing a Factory Reset.
if you're playing games and the background is constantly moving, then there should be little, or no image retention. However, if you are using Google Maps and high brightness and stationary for a long period of time (eg stuck in traffic) then I would consider some image retention could be present.
Thank you for your answers. Bold text for topics. Testing methods at the end of this reply.
Was not aware OLED screens' image retention is such a common issue, but I knew OLED screens are prone to burn-in, read about it online, and saw it on my relatives' older devices, so out of the box I turned on the dark mode and changed wallpaper to black.
I preferred regular Android's navigation buttons to gestures, because of ergonomics, due to phones center of mass (wish it was more bottom heavy), when using with one hand, balancing phone while performing gestures always feels like I'm about to drop the phone, I also find gestures to be slower, simple tap vs sliding your finger. And on top of that, I have carpal tunnel syndrome, so it's much easier to simply reach and tap. But now I started using gestures, as a burn-in preventative measure.
By the way, having Chrome open for around 20 minutes, and quickly switching to Display Tester's BurnIn detection, I can already distinguish Chrome's address bar section, and clearly see tab switcher button. This will gradually disappear, but the fact that afterimage appears so quickly and remains for so long is concerning, since I feel such image retention might indicate my display may be prone to burn-in, but of course, I don't know this for sure, just my uneducated guess.
Having dark mode keyboard open for around an hour, and I can see remnants of it even on grey backgrounds of folders.
Back to reply..
I never use my screen at full brightness, it's always set to somewhere around 50%, and as I said earlier, image retention starts to occurs in a matter of minutes. Images do gradually disappear, but it takes a long time, and when I use screen for hours with static elements, it felt like it took awfully long time to disappear, but to determine how long exactly it takes for them to appear and disappear, I need to do more thorough testing.
Yes, when playing games, indeed, a lot of things are moving, except for Heads-up Display, but I first noticed this image retention issue playing an older video game called "Super Cat Bros". That game is not optimized for such wide-screen phones as S20, so on each side you have a black bar, display is split into 3 sections - bar-game-bar. That game is very colorful and has lots of solid colors, so after I finished playing, in dark user interface backgrounds I noticed discoloration, later looking at solid color backgrounds l noticed clearly where each section was, so bar-game-bar. Because sides of a display were turned off, and all action happened in the middle, you can clearly see which part of the screen was the most active.
This is why I'm coming to conclusion, that dark mode alone is still only a small part in burn-in prevention, you should blackout everything, including websites (I remember firefox had plug-in like that, capable of replacing background and font colors), switch to a dim keyboard preferably without visible keys with orange-red colored font, download oled friendly icon packs, watch movies cropped in, so you're not left with permanent discoloration in place of "black bars", and play games full-screen, only then wear will be uniform. Seems like too much work. I wish micro-led displays would become widespread sooner.
I don't think factory reset or uninstalling apps will help, because it appears to be not software related.
At least not software user can update, such as display's firmware, but I don't know for sure just how independent display is from other phone's guts. Even then, I don't think firmware can fix this.
The phone is under warranty, since it's new, used for a few moths, and unmodified, but sadly is probably not an option, because in my country, gaslighting customers is fairly common. Service center will probably take it away for a few weeks, then return it scratched up, and say they didn't find any issue. So unless it's a serious burn-in, that's visible always and on every background, it'll be extremely difficult to make a return, and even then they'll probably tell it's normal wear, but then at least you can without explaining too much contact consumer protection and show them the problem.
Software used for discovery and testing:
• Super Cat Bros (video game)
https://play.google.com/store/apps/details?id=com.FDGEntertainment.SuperCatBros.gp
Play it for an hour (or more) and then test on solid darker pastel colors, do you see discoloration? Report for how long you played and how long discoloration was visible. Do not reopen game when retesting discoloration, because it may appear permanent. I know some people are not good at seeing minute differences in shades, but at first it should be very obvious which parts were black bars and part where game ran.
• Display Tester (app)
https://play.google.com/store/apps/details?id=com.gombosdev.displaytester
Very good display tester, free, lots of features and tests, and works on wide-screen displays, enable "use immersive mode if possible" in the settings. I think default color in BurnIn tester is very good at revealing discoloration, but you can play with sliders, just remember position which reveals discoloration the best.
• I'll also attach solid color image, which works for revealing discoloration.
And another dark gray image, which also helps reveal discoloration, use in dark room at around 50% screen brightness (play around), no matter how much you zoom in or out, it appears like screen has gradient, notifications bar icons are also visible, not sure if it's temporary or a permanent discoloration. I recommend opening these images with a gallery app, set to full screen, or simply pinch to zoom, and tap screen one time to hide gallery's UI elements. Tilt phone left and right, move towards and away from yourself, do you see discoloration?
You can also open them up with browser, and examine your screen, but I found you can't hide all UI elements, so better use gallery or other image viewer.

Question wash out/fade across the top of the homescreen display

So ever since I have had my 6 pro I notice that when I have a black wallpaper or a dark colour set the top last maybe centimetre from across the top of the display washes out/ fades out Into grey and I have noticed that changing between different colour profiles either makes it less apparent or more worse. I'd like to think it's software as I don't think it's doing it anywhere else but the home screen but I could be wrong.
I think this is a thing to show the QS panel, we had a bug on the betas where there was a line up at the top of the screen to show it too. IIRC that one occurred only on lockscreen though.
That's actually part of the pixel launcher. I hate it with a passion. My mod, which is available now, removes it by default. If you are not rooted you have to use a 3rd party launcher. If you are rooted but don't want to use my mod you can edit the image. Its called workspace_bg.9.png.
