screen brightness issue/overheating

i've had my phone since launch and ever since my screen brightness gets automatically reduced due to overheating.
At first, the screen will dim itself ever so slightly. After a few seconds later, it returns to normal brightness and it repeats itself.
Eventually, i notice upper half of my phone as well as the screen itselft getting really hot and the brightness dims permanently.
I usually keep my brightness setting at the highest level but when i go into the menu to increase the brightness setting back to highest, it tells me the brightness is reduced due to overheating. only way to increase the brightness back to highest is to turn off the screen and let it cool down for a few min.
whenever this happens im usually browsing the internet for no longer than 10 min before this kicks in. i seriously dont think im using too much cpu by browsing forums for this super phone to be overheating.
i've read other post regarding auto brightness feature causing issues but i have not enable this feature on my phone. and its kinda hard to believe that i have to lower my brightness to prevent it from overheating.
anyone having this issue? man i'd hate to return this phone and start from scratch. tia

I would love to hear more about this...My experience matches yours perfectly. Does everyone's phone do this? If enough people say no I'm going to get a new one...it is absurd. I got those phone almost primarily for it's beautiful screen which I can't see at full brightness for more than a minute or two!?? fnck that.

Is it possible for us to get a brand new replacement unit even if your 15 day return period is over? Assuming that other users are not experiencing the same problem.

Mine does this as well, I think it's some kind of fail safe if your phone is running hot cranking up the brightness is just going to add more heat so they limit it while it's running hot. Once it cools down then it will allow it again

I have this same issue, I have to recharge above 30 percent to get the point where I can max the brightness up again

Hmmmm... guess im not the only one with this issue and hoping that it is addressed in the future update. However, it seems odd that no one brought this up? Could it be that there are only a few of us that are affected? If so, im beginning to think that this is a hardware defect?

Ive had the phone since day one. I am not having this problem. The only time it ever gets noticeably warm is when using the phone for extended periods while charging. And this is not hot like some people are reporting. I would try exchanging the phone.

Mine did this the other day, I normally have auto brightness on but I was showing a photo so i went to turn it off and crank the brightness up but it didn't let me. I pulled the battery for 10 seconds and it let me do it.

I think alot people are not experiencing this issue because they either keep the auto brightness feature turned on or keep the brightness setting at a low level. I dont wanna exchange my phone if im gonna have the same issue. What can i do?

You may be on to something.... I rarely ever have my screen at 100%, mostly because its just too bright for me.
Although, I did watch 2 hours of video (1 hour from the SD card, one streaming from Netflix) at full brightness, and never had a heat issue. A little warm, maybe, but certainly not hot.

Auto Brightness Jerky

Hi all,
I just gotten this phone today. I noticed the auto brightness transistion is not smooth but rather jerky and on my set it will brighten the screen and then lower the brightness quite often even though the lighting in the room did not change. Just wondering if I got a lemon set.

I see the same thing. I hope it's not defective.

Mine does the same thing. Ended up turning the feature off, and leaving the brightness at about 50%

mine to i think it's a software issue

Exactly What I did. I used to have the face recognition to keep screen on and that was really annoying with the screen dimming every 15 seconds but with the brightness. Set at 50 I can still see the screen pretty well in sunlight.

Coming from 2.5 months of HTC One, I just got this phone yesterday! Awesome phone amid some lags here and there at times. I hope that the next update of Android 4.2.2 will iron out those issue.
Yes, Since Android 4.1, the Autobrightness is kind of "too extreme" to be practical especially the dimming of backlight in low light. I have also set it to 52% manual.

always on display

Hi
Anyone keep always on display off due to potential burn in?

I prefer always off, but the terrible implementation of double tap to wake forces me to keep it on.

No... I love it and the now playing music as well. The only issue I have is the AOD is too dim in a pitch black dark room. All other light levels it works fine. :good:

Does it move around like the Samsung phones or will it just burn in?
Sent from my Pixel 2 XL using Tapatalk

I don't use it but the AOD moves around, it doesn't stay stationary so it shouldn't cause burn in.

It does not move around on this phone.
Stays same place.
Never seen it move.

It moves a few pixels every minute. Watch it when the time changes. It's not much but it does move

Agree, it moves fractionally...

Always on is annoying to me I keep mine set to Lift to Check phone

Yeah, it doesn't move nearly enough to alleviate my concern of burn-in. Especially with this screen. On the S8 it would move all over the place, even down to the bottom of the screen. Now, that's how you prevent burn-in. Just moving it back and forth between a few small pixel variations is not going to properly prevent burn-in.
For this reason, I have always on display turned off. Not worth the risk to me.

I don't see how that helps. Burn in is caused by uneven pixel aging. If it's only moving a few pixels back and forth then it's really still the same part of the screen that is having the pixels age more than the rest of the screen.

Always on is always on here, no burn in so far. Works brilliantly.

It's much improved in the dp2. Hopefully that sticks in the final release

One question about the Always On Display (I don't want to open a new thread for this) - is there a way to have the "Lockscreen"/Always-On-Display rotate to landscape mode?
When I am having my Pixel 2 XL on the magnet mount in my car in landscape mode, it would be great that the AoD also rotates...haven't come up with an idea yet, unfortunately.

I didn't say it helps I was just saying it does move to the post I quoted. That said I've had my phone since 10/19 with AOD on ever since and have no burn in.

Ok, my misunderstanding.
I got my phone on 10/24 and so far I have left AOD off. I have "Double-tap to check phone" and "Lift to check phone" turned on.
I have kept AOD off for 2 reason:
1. The fear of burn in. You may not have seen it but it does seem to me to be the most likely thing on the phone to cause burn-in since those pixels would always be on. Between 10 and 12 (am and pm) you would have the 1 digit always on and whatever shift occurs isn't noticeable so it's likely just than the width of pixels of the 1 digit. So you would effectively have pixels literally active 24 hours a day. That kind of worries me so I leave it off just as a precaution.
2. Impact on battery life. Having AOD on results in having to render, refresh and illuminate pixels 24 hours a day. Even with the great battery life I could still see the battery life being noticeably decreased.

I really wish there was more customization options, or at least the battery status displayed for AOD.

Fair enough. I tried turning it off last night and by this morning I turned it back on. Just getting ready for work this morning I missed not being able to glance over at the time as well as seeing it in my car on the dock. If there was a way to turn it on schedule or something that'd be nice. Maybe tasker could do it somehow..

If you use Accubattery, it displays the charge level on AOD with a circle around it. After the N6P I was paranoid about the battery so installed AB to confirm my battery was solid. (106% capacity). It may be a workaround until some dev comes along and provides that without having to install an app. Also THIS ARTICLE in XDA gives some hope. See the last paragraph on "other applications". :good:

I have a question on AOD. If you are listening to Google Play Music, does it show what song you are listening to? Or do you have to go to the actual lockscreen to see that? Thanks.

Android P what have they done with the brightness?

Just installed P and now previous brightness level of 63 it's so dim? I have to have it almost on 90% brightness now, why have they messed with this, it was fine as it was

Same for me. WTF Google?

The actual brightness is the same, they just changed how the slider works. The first half moved it fast, last half moved it slower. Now the slider is more uniform.

It's definitely not smooth across the entire range, all my brightness is almost all the last 10% and actually a pain to set properly, it's worse for me.

That's more accurate because in bright indoor lighting or outside it's going to be towards the end of the scale. Dim indoor lighting I'm currently at 43%. And in pitch black it goes to 0%. I pretty much never touch my slider anymore after a couple adjustments. Don't get caught up on the percentages. I would be willing to bet that with Oreo at 40% and Pie at 90% the lumens output of the screen was the same.

Yeah I don't touch mine once it is setup generally but it's definitely not even throughout the scale, only gets really bright from like 85% onwards, just seems odd the real brightness is so high up, makes for fine tuning a bit difficult.

The screen has been rated a minimum of 1.78 nits and a maximum of 496 so if it truly is linear now, 50% is something like only 247 which isn't that bright at all.

Hi
So much for AI on adaptive brightness, it's rubbish, and why do Google try to fix things that aren't broken, who needs AI for adjusting a backlight? Seems nothing more than just being able to market the phone as having AI! Never had an issue on Oreo, had it set at 25% with adaptive brightness and it was always the correct brightness wherever I was, which shouldn't be difficult given it's got a sensor to read the light levels.
Now since Pie, last night I turned my phone on in the dark and was blinded by a bright display (Oreo it would have been at it's lowest level in the dark), so turned the brightness down, turned it again later and the same thing, way too bright, and again this morning in a fairly dark room the same thing, far too bright, so I turn it down again. How long will it take to learn? The old method it was tamed immediately, now I'm constantly fiddling with the brightness, how is that progress!
Is there an option to go back to the old method?
Wish I hadn't bothered upgrading, just another year with an Android update with changes for changes sake.
Regards
Phil

Totally agree on this. Adaptive battery and adaptive battery are almost non-sense. Only something cool to brand the item.
And Pixel Visual Core is just something super-expensive to make Whatsapp, Facebook and Twitter cameras use HDR+. I'd rather pay something less and not having this feature that is probably expensive (or modifies the perception of the Pixel 2 as super-new and mega futuristic). Also, I've got the feeling they won't use it for Pixel 3 or 4.
Moto X1 was the last to use more CPUs to optimize the phone, before Qualcomm introduced more chips.

Hi
For any one having this issue please report this from your device at Settings > System > About Phone, the more people that flag it the more likely it will get fixed.
For me, I hate these updates that break simple basic functionality and overall add nothing extra to what we had with Oreo. Google really need to test these things properly and stop trying to fix things that simply are not broken!
Regards
Phil

Already reported, i shouldn't have to have my phone on 90% to be the same as what it was on 63%

I mean, factually, yes it does.
You're just lucky you can't see it. A lot of us can, and it's annoying
