Hi guys!
I have a strange thing on my Dell Venue 8 (3830/T02D).
While the auto brightness is off, the brightness is still changing, depending on the type of content. For example, if I scroll o long page with white background in browser, and suddenly some dark object or picture will appear in the window, the brightness of the screen will change. It happens constantly when I use my tab with low brightness settings.
In other words the brightness constantly jumps, when something happens on the screen, so it's really very annoying.
For the first time I thought, that it is hardware issue, but later I google the problem and find out some similar questions, where people say, that it is not a hardware, but Android 4.4 problem/bug or Intel compatibility issue (it was written, that many Asus tabs and even Nexus have the same problem and it is called dynamic contrast, that is stupid function exclusively in Android 4.4).
Is it true?
Will the downgrade to 4.3 help to get rid of this random brightness jumps?
Is there any fix/hack to override this problem without flashing/downgrading?

I never noticed this problem but if other devices have it, and no fix was provided would be no fix for this device either.
I'm used to having my Android phones use apps like KinScreen or Gravity Screen to keep my screen on by motion. On my new Mate 10 (ALP-L29 8.0.0.119 (C636) I'm finding that no matter what I do, the phone's setting for display on time always control, even though I've excepted out both apps from battery optimization and from automatic control of their launch (manually set to run in the background). Anyone experience the same issue or have any thoughts? I don't know if this is an Oreo problem or a Miui one. Thx.
I am having the same issues, no matter what, with persistent notification active, the screen does not stay awake with kinscreen. Installed Wakey, seems to be working at least sometimes... Should be based on your eyes watching the screen...
According to TecTiq, the maker of KinScreen, it's a Miui problem. I'm not the only one to report it. Oh well....
One other possibility is to set your default screen timeout to something long, and then install Proximity Service, which seems to work well on the Mate 10 and turns on and off your screen by covering the proximity sensor. Creates a permanent notification, but installing AutoNotification cures that (as well as the other running notifications, like background Android processes, that you don't want).
EDIT: Nope, belay that! Once the phone sleeps, Proximity Service is still killed (even if excepted from Launch and Battery Optimization). Back to the drawing board....
Hey guys,
Just got my Mate 10 pro (BLA-29) Dual sim a few days ago and I am loving it!
Have updated it to the latest Android 8.0 and EMUI 8.0.
However instantly within the first hour of using the phone I noticed a strange issue or bug? Where you can be on the homescreen and the screen will be nice and bright, jump into any app it can be Chrome, whats app, Firefox even Youtube or Google Maps and instantly within 2 seconds or so the screen will dim a little, go back to homescreen or switch between apps and the screen will brighten, but then dim again after 2 or so seconds.
Have looked all over for any adaptive brightness, turned off auto brightness and any battery saver and nada, still dims.
The only difference is it doesn't happen if you whack the brightness up full, then the brightness level doesn't dim. So what gives??
Also while I have your attention, will Huawei ever allow us to Lock the phone to 4G/LTE only mode? Or do we need root for this?
Thanks for reading, I hope someone has an answer for me as I love this phone!

Known issue with brightness auto.
It's an IA thing which change brightness depending on your environment
I agree... I posted a topic about this a while ago... dims slightly with chrome, facebook etc.. isn't much that can be done about it.
I'm guessing it's to prolong the screen life (?), because these apps use predominantly white backgrounds ... but don't really know for sure...
Huawei claims this is a bug affecting every device running EMUI 5.1 and above. The standard Mate 10 also does this and so does the Honor View 10. Highly annoying. I actually sold my Mate 10 after three days largely due to this issue.
I was really excited for the Honor View 10 until I saw it also suffers from it. A fix should be simple but clearly isn't a priority.
Looks like i'll be switching to the Galaxy S9+ because of this - it's super annoying especially in sunlight - very noticeable then.
My screen does not change brightness level when using Chrome...I do not use Facebook. Non-pro version here with LCD.
mine also doing this as well for me its fine but some games it also does this not only my screen dim a little fps also drops!! and its very annoying
I confirm this behaviour on my Mate 10 Pro. Very annoying.
I have a P20 Pro and it does the same (all Huawei with Amoled does this I belive). If I enable auto brightness it seems to stop doing it. Only at manual brightness it keept doing it in certain apps.
I lurked around different sites about this problem and found this to work for me on my Mate 10 Pro. You can test it out yourself and see if it helps
1. Turn-off Power Saving Mode
2. Go to System > Developer Options > Increase Readability Under Sunlight> Toggle Off
3. Then make sure to restart your phone and open your apps (like Chrome) to see if it's still auto-dimming
Hi,
I returned my mate 10 pro because of the dimming issues as was very annoying.
I am planning to get p20 pro instead. Does p20 pro have the exact same issue despite EMUI 8.1?

I have heard of it on youtube.
this is no bug though. this "feature" has been around for years and huawei does not admit it. they alwas say its a bug and they gonna fix it but the p9 had this issure already.
Some argue that this is some sneaky way to cheat better battery life and less heating. We all know that the Kirin processor lags behind the others, it can only provide high performance for a short period after 5 min it overheats and gets thermothrottled

Can confirm my Huawei Mate 10 Pro, with BLA-L29 8.0.0.145 (C432) also dims the display when using different apps, among them the SMS/MMS app, WhatsApp, Chrome Browser and the built in Notepad app.
As well as dimming the display when »Auto Brightness« is disabled, »Auto Brightness« is automaticly enabled every time the phone is turned on and off, so not possible to permanently disable »Auto Brightness«.
Sent my phone to be repaired or fixed, and was told that the automatic enabling of »Auto Brightness« is a battery saving feature ...
Regarding the problem with dimming in certain apps, it's supposed to be fixed in a later update ... Just wonder when will that actually be ...

Previous owner of P9 with this screen-dimming feature. I own Mate 10 right now (C636 134noxloader build) and Mate 10 doesn't have this screen dimming at all, I tried chrome, youtube, and all my other apps, it never dims.

Just an update.
Wrote to Huawei Norway, and yesterday got an email telling me that Huawai is aware of the issue and it's on their list, and is to be fixed, as far as they know, in late July or August.

No, its november and nothing changed, now a huawei mate 20 pro have that bug too.
This is common amongst all EMUI devices (I think) and it is fixed by freezing or otherwise disabling the Power Genius app. If rooted, you can use Titanium Backup or Service Disabler to do this. If you're not rooted, you might or might not be able to do it via adb.
This is a battery optimization feature, and not an auto brightness bug.

Hello. I received my Realme GT a couple of days ago. It Is running global 11_A.09 software version. I'm facing a bug with auto brightness off. If i open some system apps screen brightness dims. Do you also have this behaviour? I'm considering to return the phone. Thanks in advance
Luca
Hi, I am currently facing the same problems. I've noticed that the brightness tends to dim when I open apps that have a lot of white pixels. Unfortunately I have no fix yet. Have you contacted realme about this?
I haven't contacted realme because i'm considering to return the phone. I tested different display settings without luck. Checked also for system updates but it is last release. Surprisingly i haven't read about this bug in any review.
The recent FunTouch OS 12 has a lot of features missing. It feels like IQOO has rolled up the updates in a hurry.
1. No Android 12 Clock widget.
2. No Quick Panel tiles like Android 12.
3. Dark mode not getting applied on App Drawer.
4. Etc etc
Bloody hell, when will we get Origin OS for Indian market.
This device has so much potential if they just unlock the bootloader for installating custom roms
Disabled animations in Developer menu doesn't get applied either
Also, home screen is not coming from many widgets like the one we get by swipimg right from left edge
This seems like an Alpha version without much testing and stitching with animations quite annoying like dark mode not applying to app drawer
This is almost the the first few versions when we bought the device during launch. Only after one June or July upgrade things became like a release version. Established that IQOO OS team for IQOO 7 releases updates without proper testing and going through beta testing as such issues were never encountered in IQOO 3 with IQOO OS which people for some reason criticize
Witnessing huge flashes of brightness fluctuations at night even when automatic brightness is turned off.
Still can't find a way to switch off Accessibility button

Same here. Gets blindingly bright in the middle of the night. My phone also keeps crashing atleast 3 times a day. Waiting for a fix update.

Yup, same here as well. Plus sometimes when I enable battery saver the brightness also increases even if auto brightness is turned off and manual bright is set to lowest possible value.
I still have similar issues on my Vivo X80 Pro and many familiar features like the new Control Center are still missing! What shoud that? OriginOS would be so much better, why do you have to develop such a bad operating system internationally. I don't get it and I'm actually very, very excited about the X80 Pro but the software totally ruins the experience!
