Have you tried from settings.. Settings / Display / Brightness and remove Auto brightness toggle (see screenshot)..

i told in the post i remove the v in the auto

Thermal Throttling.
Same on mine. Sucks heavy. CPU gets too hot. Display turns brightness down...

Seems It has been fixed with the new B166 update.
* Solved problem with screen (brightness) not autoadjusting when entering a dark area

No this is completely different topic

Ill wait for update then :d

wow just notice the battery is terrible also damn!!! no du much and goes down about 30% in 3 houres
but deep sleep ok during night nothing down 6 houres 100% weird.

New Kernel seems to have improved CPU usage. Phone does not get so hot anymore during gaming. Not Thermal Throttling noticed with high brightness anymore. Impressed for now.

Brightnes Control

Is there any way to increase the brightnes on the HTC Diamond.
Or a third part application that can
(that must be the light sensor indeed, you can test it easily : turn off screen in a weel lighted room, put your finger on the light sensor, turn on the screen, wait for the brightness to decrease, and remove your finger : it'll increase anew within a few seconds)
edit : sorry, wrong topic.

Are you serious dude?
Just change your brightness in settings-->system-->power-->backlight.
If you cant change the brightness on your Jewel................we are in trouble
I guess your not visiting the kitchen right?
In the Old HTC touch the Brightness setting was under the Display settings, not the power settings

Well, i had the same problem when i bought the HD. Since i'm a extreme noob and never had a WM device before, it wasn't easy to figure it out. But after playing around with the phone for a couple days i'm able to solve the most 'problems'

[SOLVED] lower brightness option for night time browsing (like night mode)

Hi all, I was wondering if anyone new how to lower the brightness level to below that of stock, up to the level of night mode if I needed.
I like to do a bit of browsing before I sleep, and the brightness levels even on the lowest hurt my eyes! If anyone knows how to do this I would very much appreciate it. Thanks!
UPDATE: Issue helped, and possibly resolved with the help of my mate Rich @ Geek you Up. Check out his app in my thread:

Ive been looking at the Auto-Brightness thread and it seems Cyan already knows how to tweek the brightness values, but I dont even know what a github is let alone the deving needed to acheive this.
cyanogen said:
Anyway, the Desire has 10 auto-brightness levels, and the N1 has only 5. These are just an array of lux/brightness values. I put them into my vendor overlay and rebuilt, and I have to say it's much nicer. I'm going to include it in the next CM.

Cyan if you can help, I would appreciate it!! But understand if the modding is far more important
Like how the brightness dims before the screen auto turns off, or how it is dim when you tap the sleep button in the clock application - these would be good. As for that stock widget that controls the wifi,blutooth,gps,sync and brightness, i never touch it because it messes with autobrightness, but if it could be changed to temporarily go really dim thatd be perfect

Either my friend! The clock application goes even dimmer than I want, so somewhere in between would be great. But I'm sure that could be customized, I just dont know where to start looking..
I'd be really interested in this too - I like reading in bed before going to sleep, but the wife doesn't like the light being on. I have to angle my nexus slightly away as it is too bright, even at the lowest setting, to have it directly facing me while in a dark room.

automatic brightness behaviour

Hi!
The automatic brightness on my Xperia Z behaves weird (altough I think it is a bug)
This is what happens:
I have the phone set to "adapt to light conditions" (automatic brightness)
Now when I slide the brightness slider, the brightness changes. But, depending on the setting of the slider, it will not go to full brightness or darkest on its own. When I turn off "adapt to light conditions", it becomes brighter or darker, depending on slider position. But it will never go to 100% on it's own, not even directly under a lamp. It also becomes a little brighter when I turn off automatic brightness and have the slider set to 100%.
Expected behaviour:
I turn on automatic brightness, and put the slider in a, let's say, 60% position. The phone goes to 2% brightness in a pitch dark room (when I read in bed) and switches to 100% when I'm outside in the bright sun. When it does not sense extreme conditions (e.g. sensor reading <20% ambient brightness or >80% respectively; then gradiently going to darkest or brightest gradiently, of course), it aims for the +-60% brightness I specified with the slider.
Conclusion: The slider is an overall threshold for screen brightness and it does not adjust in a 2-100% brightness range, but around maybe +-30% or so around the position the slider is set at. This sucks!
This seems to clearly be a bug, and imho this contributed to the somewhat "not so impressed with the screen" reviews I read before I bought it. Because the screen is really very good if it is set to the correct brightness.
Thanks for the answers!
PS: When I enter the service menu with *#*#7378423#*#* and check the ambient light sensor, it gives me values between 0 and 1000 - so it does definitely work correctly. Build number is 10.1.A.1.350 - I know there is a newer one, but my phone is carrier branded (3 Austria, for that matter) and hasn't been updated yet, unfortunately. Can someone confirm that is is fixed in .434?
x-post from talk.sonymobile.com
I dont think this is a bug. It's been like that on the t, tx, v since they were launched.

Really? This is almost a deal breaker for me :/ that is a really stupid behaviour, what do I need automatic brightness for if I have to change it myself anyway? I really don't want to care about this miniscule thing on a 600€ device - I expect it to adapt to all conditions.
I didn't want to root it or put a custom rom on it - Sony did a good job with the software as it is, except the automatic brightness.
Sony phone has the best auto brightness
You can find on any phone.
You can say Samsung's auto brightness sucks but not Sony
In auto mode you have the choice to set the minimum brightness level you want and the level will go up depends on the lighting situation and sensor reading.
Yes it has some threshold limitations but it's very sufficient.

Sorry, but "best auto brightness" is not what would've come to my mind thinking about the xz and I would never buy a Samsung plastic brick
I had a Nokia N9 previously (that I miss dearly, but the internal 3G antenna was broken so I had to replace it... still by far the best phone I ever owned) and it had exactly the auto brightness behaviour I expected - when I read in the dark, it when down to the lowest possible setting. And when I was in bright sunlight, it went to full brightness wihtout a delay or hassle. I could read it perfectly under any condition and never thought about the settings. The slider only indicated a preferred standard brightness - always had it at 60% and it was perfect.
I really don't understand why other manufacturers wouldn't do it exactly the same way? As I said before, why even have an auto brightness setting if I have to go to settings to adjust it anyway?!?! If I put the slider on 60% and auto brightness on, it burns my eyes in the dark and I can't read it in bright sunlight - I even have to adjust it when the sun shines through my windows at work?!?! WTF Sony?
We are talking android here
I don't know if you had the chance to use gingerbread,froyo....
Maybe android has some limitations.

iirc it didn't annoy me (and boy am I picky about details like that! ) on the HTC Magic (up to the last CM that supported it) and the Nexus S I had before the N9... anyway, seems I have to get a decent brightness toggle widget :/ (maybe you can point one out?)
but thanks for your replies!
just for the record and anyone who may find this thread in the future:
I just installed "Auto Brightness" and it seems to work well and has tons of settings. Would have preferred a more native solution... I hope this doesn't drain the battery.

The note 8 sun mode kicks in even with auto brightness turned off

Ok guys so I need to know if there is a sensor issue with my phone .I don't use auto brightness no more because if you go in the sun the brightness overrides itself to brighter than max brightness and it is the reason why I've had burn in 4 times so far and had to get the screen replaced. But I've also noticed that with auto brightness off but you have the brightness maxed out and go in the sun or shine an led torch at the sensor the screen will kick up to override max brightness sun mode out like when using auto brightness. Is this normal behaviour. Can anyone test this fpr me please .only 6 months left of warranty left
So if this is a feature its stupid ,and make sure you never put your phone on max brightness in manual or autobrightness if out side and it's sunny as it will kick in and cause screen burn .
I've factory reset it and cleared cashe still the screen in manual mode if maxed out in the sun with the brightness maxed out will auto ride to super max brightness mode .im on the oreo uk fm
Phone is uk unlocked note 8.
Anyone? I see lots of views no replys I'm sure everyone that view this thread owns a note 8?
OK lol thanks for the great respone guys smh this place sucks :good:

No, this place does not , if you do not get any response , it means nobody has something useful to share, beeing rude will gain you a ban
Maybe your the only person that has this error, so no one has any advice to give other than to factory reset (which you all ready done).
Most people has moved on to other phones. So you'll have to be patient. I say is take it to the Samsung store and see if it is covered under warranty.
I'm not the only person all note 8s do this i think but nobody in this thread owns a note 8 or 9 other than me because they both do it. On both my phones.its a terrible feature as it will cause burn in.if you want to be able to see the screen outside in the sun
So i've been using auto brightness for 2 years, i don't have any burned screen. Last week I've been using phone on sun, taking a lot of pictures (brightness set to auto, on camera app its option to set it to max bright) and still no burnout. I think you should say your problem to guy who will accept your warranty next time
Well this is good to know just went to the sammy service centre and tested the phones they had there with my led torch and they all do it including the s9 plus .so it maybe always was like that or it's been added into a fw.

I will add that friend have a s8, his screen is good. Also another friend had note 8 and now note 9, always autobrightness on, no problems so far.
I have a little experiment
1st, I set auto brightness on, turn on a torch on the sensor, brightness go to max, then turn it off, and brightness go to middle (room light on)
2nd, set the auto brightness off, slide the brightness to minimum, turn on the torch to sensor, and brightness remain to minimum, nothing change
So I assume maybe it's a software feature I don't have, you can check with your friend running the same firmware, or you can check using *#0*# on keypad, click on sensor, look for light sensor, and do a simple test, see how much lux you have when you're on direct sunlight, or in a room, then you can flip your phone down / reverse the light source, the lux sensor must be read it on continuous count, as you flip your phone, the number will get decrease
I hope you understand what I am saying, because English is not my native language

You did the test wrong friend you need to turn off auto brightness and slide the brightness slider to max brightness it must be fully maxed .then shine led torch at the sensor then the brightness overide kicks in and goes even brighter just like In auto brightness mode.but if the slide is not fully maxed it won't do it

Interesting you mentioned all devices do this before you went to the service centre and confirmed it. That admission renders your entire post pointless. If all the devices does this, it means it's not a fault on your sensors or anything on your side, and it means it's indeed just a feature.

I said imo that all devices have this issue. Because bothe my note 8 amd 9 have the same issue .and i found a thread on reddid where 2 others also had the same issue.its not a feature because it can damage the screen it must be a software bug that Sammy need to fix

Ah I see, after doing that, I found out that the screen goes brighter and the colors seem to be fade out
Maybe it will help us to watch better when we got under direct sunlight (I think it's not a bug)
But in real life usage, I have my adaptive brightness turn on, then when I think it's too much bright at the moment, I will manually adjust it to my desire brightness
So that the system will learn the pattern and will apply automatically next time I had the same condition
Doesn't do that with mine and I live in Hong Kong.

Auto brightness - screen is too dark

Hi.
Anybody else have problem with auto-brightness? For me the screen is too dark at night. I'm using stock firmware with all updates installed.
I have the same issue.... I still waiting for some custom ROM.... Maybe some one fix it

I'm having the same isuue on redmi 8. But i think it's due to MIUI 11 or some aggresive adaptation. I have a redmi 6 which have the same issue (although it has no auto-brightness), the screen gets too dim with no reason (as if i scroll the brightness bar to the lowest setting).
I have the same problems of auto brightness which is too dim on dark places, is there any solution even with root ??
Yes , there is actually a solution : Turn Off Automatic Brightness. Why do you guys turn on Automatic Brightness ? I never set it to Automatic.... first of all, Auto Brightness will waste more battery.... I just keep my Brightness to about 25% always... no matter if it's day/night...
