Play screen flicker in games (Auto brightness?)

I have an Xperia Play currently on the stock ROM, fully updated.
I noticed that sometimes when playing some games, the screen seems to flicker as if it is changing the brightness settings very rapidly.
I did a Google and could only find a few other people having the same issue.
Is this just a normal thing with auto brightness? Sucks that you can't turn it off...
Cheers

You can turn it off, in the update 2.3.4, the Nordic Generic one, at the mo..works quite well with it off, screen looks a lot brighter(obviously!).
I was always under the assumption that auto brightness ran more battery with it's sensor always being on, at least that's what happened with my last phone.

Did you notice the screen flicker im describing?

Update to 2.3.4 to turn it off, or buy hatcyl's 'disable auto brightness' for .99$..

the auto brightness app requires root so make sure you are rooted before you buy.

Yeah, in exactly the same way, also if the light in the room changed, or you would put the phone in shadow for a second, like when moving it, the sensor seems to go into overdrive.

Autobrightness bug

Hello little birdies.
I am having an issue with my auto-brightness and I would like to know if anyone else has experienced this.
Whenever my auto-brightness shines through the power of the sun (goes to 100%) it seems to get stuck at full brightness and my already not so good screen-on time takes a dip and I always notice this too late . I use the quick settings widget which is preinstalled and the A for auto-brightness is set but when I click it the screen immediately lowers the brightness, while the A for auto-brightness remains, and a vain in my forehead pops.
Furthermore after checking badass battery monitor it shows that my screen is often at 100% sun shadowing brightness. Today it was at full mutated power the whole time. Anyone got an idea as to what could cause this? Anyone?
PS. You might have noticed in the text above that I think the screen is really bright when at full power and that I can see the screen perfectly during a warm ball-soothing sunny day.

Yes, I have a bug with auto brightness too. It seems to deactivate itself. I have activated it a couple of times and everytime it deactivate itself at 100 % after some use.
I have an international HTC One X with the latest 1.29.401.11 update.

Glad to know I'm not the only one. I will soon factory reset my phone to check if it magically gets better.

I noticed this last night. My phone was blindingly bright and I didn't understand why it was set to 100%. I set it back to Auto and so far its still on Auto. i will have to keep an eye on this.
HTC really need to fire the monkeys they have working as coders. I guess if their software is not fixed up in next couple of weeks there might be a whole lot of people, me included, who will migrate to the SIII (given of course that it doesn't have a gazillion bugs as well).

I've been trying all day to recreate the problem but ist not doing it. I put my phone in the sun, I tried using the camera app, I used the video app with its 100% brightness setting, but the phone is still showing Auto brightness.
Any ideas on what triggers 100% brightness?

I have the same problem with mine. It's just randomly turns off auto brightness

I don't know either what triggers it. It seems to deactivate at either 0 % or 100 %.
I don't have many apps installed, if I just do some web surfing and put it to sleep, when I wake it up the auto brightness is deactivated, in maybe 1 of 4 times. Irritating.

For whatever reason i haven't been getting the auto brightness bug for the past three days. Not sure how it resolved itself since I didn't get any software updates.

If you watch a video you can change the brightness and will stick and not go back to your original settings.

No, that's not the trigger. I investigated that on my phone and found no link.

I take that back. You are right! It seems the brightness setting in the movie play is the culprit. Although it doesn't always do it. One more thing for the chimps at HTC to fix.

Yesterday the auto brightness bug kicked in right before my eyes. I was browsing the web in total darkness in bed, when suddenly I was blinded by 100% brightness. So it's not just the movie player brightness that causes this issue.

Just got the autbrightness bug with the camera app. Everything seems to ****ing set it off now.. :banghead:
Sent from my HTC One X using XDA

Yeah. That's because the camera jacks up brightness for outdoor visibility. They need to have an option to disable that.

I realize that, however it doesn't always do it. Also sometimes it will kick into 100% brightness without using the camera or movie player. It seems completely random to me.

mine is stuck at zero. started this morning and I did record a video actually.
auto just takes it.to zero.
but also, if i change it directly from the srttings menu, its not.effecting at all, just staying at the same previous custom level.
whrn using widget, just turns it to zero.
opened the video player, changed brightness level and its normal now. it was in the middle, the video brightness level
ok just edited this post and its malfunctioning again.. arrrgh!

Try an application that controls autobrightness, it should fix the problem. I would recommend Lux Dash.

So it is the widget, powertoggle.
Once I fix the issue by changing video brightness, it works fone, till I toggle the widget to use auto-brightness.
Several comments on PlayStore also confirms this with several phones.
Just don't use auto brightness from powertoggle. It is actually doffetent.from what OP describes, but.people may come up to this thread while searching, so I think it willbe useful to post here.

Odd "screen tearing" issue

Hello guys, I just updated my note to the latest DMA6 stock rom as I saw a lot of good reviews regarding battery life.
However, I was just stdading at my desk and as soon as the phone booted up after the flash, I noticed some massive tearing which annoys me as hell. For those who don't know what it is, it feels like the screen refresh rate has been drastically decreased. In order to detect it on most note 2 you can follow these steps (well most of them are working this way, because I have tested this with some other notes):
-- just lower your brightness bellow 30% go into a dark room and keep looking at a fixed point while moving the phone up and down in front of your face, this while having a bright image on it. If you see a flickering image you're a victim too:S
Another way to notice this is looking at your screen trough another (phone) camera...you will notice the old CRT effect of some horizontal lines scrolling up
I had this on my 4.1.1 as well but only till the brightness was at 40%. On 4.1.2 it goes all the way till 80%.
Being pissed to the max, I flashed my 4.1.1 backup and guess what?! Tearing gone at 40%, thus it seems to be an issue with the latest kernel.
For those wondering...yes I have disabled the screen power saving option in the power saving menu.
Has anyone noticed this? Does anyone knows how to fix it?
Cheers

If you mean to say lag then. Factory reset.
Sent from my GT-N7100 using xda app-developers app

I never recall mentioning lag whereas you probably refer as to graphic rendering delay. The phone's interface is acting as it should be, it is as smooth as expected, no issues there.
Perhaps this video will describe better what I mean http://www.youtube.com/watch?v=vL_6H-0GD3Q You can see the screen flickering very clear. This is why I mentioned that you can test this in a dark room by moving the phone reproducing the old crt effect
My question is why does the flickering/tearing dissapear on some roms at 40% and on other above 80%?

Auto Screen Brightness Erratic

Anyone else having this issue? Sometimes in well lit indoor environments, it will be dimmer than I expect and then suddenly ramp up to full brightness.
Likewise in dark environments it will be dim and ramp up suddenly as well.

Yeah, I have that aswell, sometimes it's not perfect at all, I hope there will be some optimizations.

Glad I am not alone. Hope they'll be good with software updates since currently they are known for not being good in that department.

I was really happy to see that option in settings. However I was irritated by how erratic it was. Disabled it.
Even ambient display doesn't work correctly for me everytime. It's kinda random too

To be honest, I think it's partly a Marshmallow issue, as none of my MM phones have had decent auto brightness

I wish I could agree. My Nexus 6 had great auto brightness on L and M. Never had this type of behavior until the OP3.

Might be because OnePlus has implemented their own content adaptive back light like on the OPO. I turned it off by setting a 0 in the file /sys/devices/virtual/graphics/fb0/cabc
Not sure if that file is there on the OP3 but it's worth a shot

I turned it off in the settings and it was fine. I just wish I could have normally functioning auto brightness lol.

I just got my OP3 and have an issue with adaptive brightness, not sure if this is a behaviour that others have seen or if I have a defective device, perhaps someone could advise? My phone is running 3.2.1 and is fully stock, I have adaptive brightness enabled as I always have on whatever phone I use, when I activate the screen or it turns on at the receipt of a notification the brightness is at the approximate level it should be according to the position of the brightness slider and is perfectly usable. After a few minutes, this varies a bit but never more than five minutes, the screen dims to what I think is the lowest brightness level which during the day makes it difficult to see anything on screen. I can get back the previous brightness setting by turning the screen off and then immediately back on but then after a further few minutes it will dim again. The phone is not responding to any change in the ambient lighting as this is always constant and there is no obstruction to the sensor on the front of the phone. I can get a constant brightness level by turning this setting off but it can be a pain having to manually adjust when I go outdoors for example and this isn't the way I like to use my phone. So, is this a hardware fault or just a very poor implementation of adaptive brightness? I'd appreciate any feedback as this is spoiling what is otherwise a great phone.
Thanks

What should we do for this scenario. Should we raise a complaint or wait for an update. I have my phone in warranty. I am sure all of us would have it in warranty.

I've had issues with that feature since day one with my op3. No update has fixed the adaptive brightness issue, and it's the same with all of the custom ROMs I've tried. Has to be an issue with the phone. I'm hoping a software update fixes it because it's an obvious issue. In dark light, my screen dims so much that I can't really read anything on my screen.

Auto brightness is just bad on the OP3.. I've installed Lux to ease some of the problems but I'd like the standard AB to work correctly and not need an additional app..

Can´t dim the brightness at all CM13
Hi,
I have an issue were I can´t dim the brightness at all!
Killing my eyes!
Any solution?

With last 3.5.2 is been solved

Brightness issue

I got a a70 today and I love it but one issue is very annoying. I like the brightness high(about 80%) and sometimes without a reason the brightness goes down even tho the slider is still at the same level.When the brightness goes down, if I move the slider 50 to 100 there's no difference the brightnes stays the same. After a while it comes back to the good level. It happens a lot when I'm using the phone and charging at the same time, I assume its because the phone is too hot but sometimes it's not that hot and it still happens. Any way to fix that ? The adaptive brightness is off !
When I got the issue, if I reboot the phone, the brightness is okay for the first few seconds and then it goes down so it is most likely a software issue, not a hardware issue.
Thanks for the help.

turn off the adaptive brightness

Make sure you have the latest firmware. There was am issue with brightness on the earlier releases, not sure if it was exactly what you're seeing or not but worth a shot.
Also, don't run the brightness soo high. It's a sure fire way to cause turn-in. I find less than 50 is more than enough unless I'm in direct light

Bug
It's a software bug. I'm on latest fw and brightness is still glitchy. January 2020 and still not fixed.
