[Q] Brightness changing automatically on GPE - G Pad 8.3 General

I got my GPE yesterday and while setting it up, I noticed that the brightness would change on its own intermittently from the same bright white that I have on the LGE I picked up last weekend to something like what folks are describing as the more yellow-tinted display on other threads. Note that I do *not* have auto-brightness enabled! This is happening when I have the brightness cranked all the way up to 100% without auto-brightness.
If the screen were yellow-tinted all the time, I'd think it's the same issue others are reporting, but since it does vary between the two randomly, I'm thinking/hoping that it's software and not a hardware issue. Does this sound familiar to anyone else? If so, does anyone know of a way to lock it in on the brighter/whiter setting?

My GPE is doing the same. Brightness will either dim or brighten on its own. It's a very subtle change, but definitely noticeable. Also its very intermittent and I've only noticed it in chrome, Google now. I also have auto brightness disabled and brightness at or near 100%.

I contacted Google support and they're sending me a replacement. I'll post here as to whether that solves the problem or not.

Just got my replacement for the exact same issue. Unfortunately the new tablet does the exact same thing. I originally had the LG version and never had this problem. Only in the GPE edition.

Exact same experience here. My Galaxy S4 does something similar. I found one thread the other day saying that Android lowers the brightness automatically when the device temperature hits a certain level (95F, maybe?). I've never seen this on my other Android devices, but I'm kind of resigned to this being the case. It's really my only nit with an otherwise outstanding device, so I guess I'll live with it.

Nexus 7 Backlight Flicker?

Does anyone else have this problem with their nexus 7? I just got my nexus 7 today but I noticed that the backlight seems to flicker randomly
It doesn't look like much in the video but it is very noticeable and gets annoying when you're reading an ebook like i was.. Here's a video showing the problem.(It's near the end)
VIDEO LINK: h**p://db.tt/28eD0NLk (It happens around 9 second in) (change ** into tt)
For whatever reason this forum would not post a video link to show the problem.. for those who wants to know what it looks like please PM me..
But basically the screen flickers randomly ..
Is this a software problem? Should I go back and get it exchanged?
I don't see a video

I've had a similar problem as well. It seemed to happen to me on auto-brightness when it was changing the brightness level. I can't say for sure though, just my observation.

I havn't tried it yet..do we know if it's a hardware problem or software?
I just got it today so I can still return it if it turns out to be hardware
We really dunno at this point, but we are speculating software since both HTC One X and TF300 had similar problems and were fixed with firmware updates. Also someone switched it three times and all of them had this issue. Also try to run the screen in a pitch black room and tell me if the screen flicker is there. I may have a theory but need some other people to see if their units are behaving the same way as mine.
You can still post the link when you alter it a bit, insert a few *** into it, for example.
I turned mine on as soon as I got hold of it, no flicker, managed to go through and set up things, powered off and left to charged.
Coming back to it the screen would appear to turn on and off randomly, I thought it could be an app controlling a proximity sensor (I have one on my phone and I was EXTREMELY tired!), when I took it into the light there was no change.
I found that shaking it would help it flicker on and off at all intervals but didn't fix it. In the end I just started pushing random areas on the back, just before the issue went away I pressed around the bottom left quarter of mine and haven't had an issue since!
Glad I wasn't the only one with the problem though and would love to actually find out what it was.
Hope this helps!

Try this video,
h**p://dl.dropbox.com/u/13153603/Videos/VID_20120715_100253.mp4
it is using google map and you can see the constant flickering.. It doesn't look very severe in the video but it is actually very noticeable and annoying
I have the same issue with mine. It only seems noticeable when I have the brightness set to the lowest setting and on a page that is predominately white. I don't think it's the proximity sensor though, because it happens both when I set it manually to the lowest setting and when I'm in the dark and the tablet sets the brightness all the way down itself. Hope the next update fixed this, because it's really annoying!

I first noticed this flicker in a darkened room, so yes, it is definitely something going on. I'll try disabling auto-brightness to see if that matters.

I can attest that the flicker is ever present in a pitch black room as well.
Like this?
There are a few videos on youtube, but i cant post links but if you do a search you can find it
I noticed a flickering in chrome yesterday. But only in chrome and only while the page is rendering after it fully renders no more flickering.
Everyone turn off wifi and I guarantee it will go away. It happens when using wifi which makes it hard to believe that a software update can fix it.

Screen flickering in direct sunlight?

Hello,
I picked up my GS4 about a week ago but haven't really used it in direct sunlight until today. I was outside, and the sun was shining brightly on the screen. Home screen was fine, and darker images were ok, but if I were to go to an app with a primarily white background, or open up something which used the keyboard (texting) the screen would flicker pretty noticeably. Brightness is all the way up, and auto tone was off.
Has anyone else seen this?
yup this is normal esp when using the keyboard.
Im not sure if it will be fixed.

I guess my question is, is this a hardware issue with many GS4's or a minority. I came across a thread on the Tmobile GS4 forum where people were experiencing it, but it seems not everyone is.

Its a hardware thing, but also its only in touchwiz so a developer might be able to turn it off so to speak.
It adjusts the color and tone no matter what to save the display from overheating and or burning in...
Does it a lot and I notice it cause im weird about those kinds of things.
If you use CM 10.1 or AOKP its gone.
ive made some progress with the RGB light meter on this; hoping a friend can write up some code so we can test out a 'smoothed out' transition and sampling rate and one that is sped up, averaged faster, but will take up more CPU and RAM and battery but more accurate.
here is another thread regarding it:
http://forum.xda-developers.com/showthread.php?t=2280715
http://forum.xda-developers.com/showthread.php?t=2284726
Maybe if someone who is using CM10 or AOKP could test it to see if it is a software issues and not a hardware issue?
edit: slade and jet replied while I was writing this...thanks for the info. looks like it is touchwiz related.
edit2: just went out in the sun again to test a lot of different options in the display settings (which none worked) but is seems it is only happening when the keyboard is enabled. I am using swiftkey.
yeah TW and that sensor communicate; i believe the sensor itself probably works better ALONE, but TW changes it and throttles it for either battery or screen safety.
It is always dependent on what is being pulled up on the screen, though it can be mitigated quite a bit if you disable all power saving and screen auto features, and leave brightness under 80% or so.
yea anything under 80% in direct sun is basically black. all power saving and screen auto modes were disabled. i covered up all of the sensors too and it still flickered....

Not just a sensor thing per-say.
It's hard to explain, they most likely did it because they didn't want the amoled to burn in.
Its the same reason why the brightness goes up another 34% or so on auto above the max brightness. Only uses it when needed to save the screen and battery.
Does it on youtube too btw, bring up a video on wide screen then tap it and you'll see the drastic color shift
I noticed this thing when I got my phone also. I thought I was just imagining it but I guess it's an actual problem

No that's not possible, its hard coded into touchwiz, this isn't a bug or anything...

Dimming the display to reduce over heating?

Alright so I just got my Note 3 here in Canada (SM-N900W8) and whenever I download an app from the Play store, or do anything I would normally do on a S4 or HTC One, the phone lowers the screen brightness (usually keep it on full brightness). When I go into Settings > Display > Brightness, it says something along the lines of to ensure your phone doesn't over heat, your phone's brightness has been lowered. Now, I've noticed this happen a handful of times, and I'm wondering if anyone else is having this problem?
I don't think the phone should be doing that over simple task like downloading apps. Might want to take it back asap and exchange for a new one.

Yes, mine is doing the same exact thing. When it first started happening, I thought there was something wrong with this particular phone but then I saw that same message. It's annoying have the screen change brightness like that.
I notice when browsing web page it does it too.. can anyone else confirm? Test by turning your brightness all the way, then download a few apps and browse the web. Let me know.
same experience
Hi! Very new at this forum. Just searched the net because of the same problem. The screen keeps dimming even if im using it. I thought it was a problem so I had my unit replaced. I have a new one now but it still does the same thing. It still dims randomly. Now I dont know if I should have another replacement or if this is normal.

I think the dimming may be caused by settings>device>display>auto adjust screen tones. And/or screen mode check anything but adapt mode. .. That solved it for me.

I haven't got the Note 3 yet partly because of this. When I compared my Note 2 to the Note 3 in the At&t store I noticed the Note 3 was definitely not as bright, while being obviously bluer. But I also caught it dimming itself too, very quickly but couldn't get it to reproduce the behavior. Changing the display mode didn't affect any of this. I've wanted to see this amazing improved display everyone talks about but I haven't seen it yet - certainly not when the brightness is set manually.
I wonder if this dimming display thing is a new normal, that they've made the brightness more an automatic control now. I have no idea if this is to save battery (but then why not let the user choose) or if these new screens need to be protected more from overheating.

What's the point of full brightness if it's going to auto-dim all the time? I ended up returning my Galaxy Mega for this very reason.

I'm on my third... and posted already in your thread! for me this throttling happens all the time, gallery indexing for example triggers it a lot!
to clarify:
this throttling has nothing to do with settings a user can adjust, it's logic must be kernel implemented! no auto-contrast setting would help! and it happens even when you are on manual lowest brightness. on my devices the screen would switch even then in a cycle of ca. 20s between a additionally dimmed and the set state...

brightness fluctuating?

Hey folks so i bit the bullet and gave my dna to the wife (still love that thing) and got a brand new G2.
Something weird is up w the brightness or contrast on this phone though: even w auto brightness off and brightness set to minimum the brightness seems to randomly adjust itself when interacting w the screen. Is this a bug or some kind of feature im not aware of? The DNA had it a bit when scrolling but nowhere near as noticeable as this.
I've noticed this as well and from my understanding this is something that all G2s have.
From what I have found this only happens when the brightness is low (i.e. less than %50) and has something to do with the phone trying to adjust the brightness based on what is being displayed on the screen. I have noticed it the most when using the XDA app when I'm scrolling down through a thread; the display brightness seems to randomly jump up and down just a bit as you scroll down with your finger. If you're not scrolling the brightness won't jump up and down.
Initially I thought it was just something goofy with the auto brightness, but as you pointed out the 'flickering' still occurs even when auto brightness is turned off. Hopefully this is just something that can be fixed with a software update as it is a bit annoying.
I use lux brightness app now and have no problems with this issue,it was an issue before.

I've noticed it too. Even with automatic brightness off, CABL turned off, and brightness at 68%, it'll still do it. I've poked around with Xposed, and I have yet to figure out why it does that. I've heard speculation that it's controlled in the kernel, so hopefully a kernel dev can figure out how to disable it.
I noticed this as well but its completely gone on on these new AOSP ROMs. If you are looking for a solution this is the best IMO.

Hmm i just noticed theres a "content adaptive backlight" app running..wonder if thats the culprit.
This thread seems to debunk that theory as disabling content adaptive backlight seems not to do anything.
yes it's cabl. many posts of mine were about this. we've come to the conclusion it may be activated on the kernel level bc changing anything in the app or build prop does nothing. it's gotta be kernel related. but yes it's content adaptive back light. it sucks.

I noticed this on my Nexus 7 2013, it's really annoying when you want to say read in bed and the lights are off it's far too bright. I found using the app Brightness Adjuster solved this. It lets you go way below the firmware level of brightness and I have found it excellent. May work on your NIII.
