Auto screen brightness

Is anyone else having issues with the auto screen brightness? I'm in bed now with all the lights off and my screen is at it's brightest. As far as I can remember, the screen has never gone dim for me. I have always had to do it manually.

Mine seems to work. I always thought it worked based on where the bar is set prior to the checkmark.

I use Quick Settings to adjust the brightness. The auto on this phone definitely isn't working correctly.

Mine works just fine. Dim when it's bright around me, bright when it's dark around me.

I feel like mine does change some, but it never seems like it's a really accurate change to the condition... or maybe I just think it does, hmm.

That's backwards. You want the brightness down when it's dark, because less light is needed to see the screen, and up when it's light, because more brightness is needed to see the screen.

I as well have had issues with the auto brightness. It never seems to change. I manually set it, or leverage a widget.

Mine works but it adjusts too frequently. It was annoying to see it going brighter and dimmer every minute or two so I tuned it off and use a widget.
Thanks, Robrecht

Glad to see I'm not crazy and imagining things. Very surprised at how many little quirks HTC let slip by on the thunderbolt.

I have always disliked auto-brightness. At night when I'm reading a book in bed, it is just way too bright at the lowest auto-bright setting. Though it was nice to automatically brighten up when I'm outside. Now days, I just stick an Android power control on the home screen and manage it myself. 0% for when I'm in bed reading books, 30% for normal every day use, 100% for when I'm outside. It seems to help the battery quite a bit too.

Its best to adjust it manually anyways... Just add a widget on your home screen lolz

What's best is not always whats preferred. It's little things like auto not working that make me miss my cyanogen'd droid 1

Notice of changing screen brightness?

Has anyone noticed that the HTC Sensation's screen continues to change it's brightness automatically (in a bad way) continuously? I will set it on auto brightness and if I open the camera or go outside and it's really bright, it will change from auto to full brightness and won't dim unless I alter the settings again.. Bug? It's annoying.. Is there a fix? If not we need to notify HTC for a required update.

This really should have been posted in the "General" section instead of here, maybe a mod can move it...
I have noticed this as well. What's a little more annoying is when it dims down it doesn't do it gradually like my HD2 did (and many other HTC devices). Instead it goes from bright to dim very abruptly and tends to jump back and forth often.

I actually haven't noticed this at all. Got my Sensation yesterday. I will keep my eye out for it now, but maybe it's a bug...

Does yours gradually get dim when the screen is about to turn off or does it adjust abruptly?

I agree, I was playing a movie on Netflix app and it looked great. Then whammo screen went dim and it looked to dark

Not that I'm aware of, my HD2 gradually gets dim which is nice. The last device I owned that did it this way was my HTC Blackstone (HD).

Pretty sure its a feature of the auto brightness. It adjusts to its surroundings. I uncheck mine and set the brightness level to where I want it so it doesn't do that.

Mine sometimes abruptly changes too. My MT4G was a LOT smoother with screen brightness changing. Yes it is annoying when it happens.

Mine dims as smooth as my girlfriends butt. But when i installed juicedefender it jumped instead. Had to activate screen dimming in troubleshooting for it to go smooth again. Also it doesn't go as low without juicedefender

there's a thread in the general forum discussing this. it has to do with the widget not knowing what to do on qHD. search for the thread there since I'm too lazy right now to find it & give you the link directly

Isnt Auto Brightness supposed to do just that? Automatically change the brightness? The thing is in a lot of custom roms it never works properly but that's how it should work. It uses the light sensor..In lower lights it will automatically dim, the lower the light, the lower the brightness will be. in brighter lights it increases the brightness so you can see the screen. So if you're inside and it's dim and step outside into the direct sunlight of course it will become brighter and it will seem like a drastic change because you just made a drastic light change. If you had made the change from being inside to outside and the light gradually got lighter the screen would still get brighter just not as quick
EDIT: opps nevermind. I misread the OP. I didnt see the part where he said the brightness wouldnt return. lol reading too many threads at once.. lol

I have three stock HTC Sensation 4G's in the family.
Initially, I thought my wife was messing with the settings which is why the Auto settings for 'display brightness' was constantly getting unchecked. I asked her about it and noticed that the same thing is happening on all three phones.
So looks like this is a bug on HTC's side. I am already peeved that it's 3+ months and there's no sign of 2.3.4 with Google Talk video yet.

Camera flash bug?

I bought my g2x about a month ago on Craigslist and I thought everything worked fine, but I noticed that when I'm in the camera app that my flash doesn't come on at all unless its set to auto or if I'm in the camcorder. Is this bug?

Does your light turn on when it is switched off?
Sent from my Calculator with Android.

While in the regular camera no, only if I set to auto and take a picture it flashes, but if I try to set it to just stay on it doesn't come on at all only in the video recorder mode. And I noticed while its on in video mode if I switch the flash off it turns off and flashes for a second and stays off.

Because it works like that. The flash will only light up (when on) upon capturing.
It is already a flashlight when it stays on and not camera flash anymore.

But my problem is when its in the mode to take a picture why would you have the option of auto, on, and off ? So auto works and off works but to just have the flash stay on without taking a picutre doesn't work with my previous phones it would just stay one but anyway I guess it not to much of a problem. As long as it works.

If you want to make the led flash stay on, get a flash light or torch app.

Photos look terrible in gallery.

So I'm using the factory camera and gallery, has anyone noticed how the display turns to crap when you view pictures? The color tone completely drops and makes the photos look dark and terrible. Is there a setting I may have turned on (or off)? Or is there something third party I should use perhaps?
Because when I view the photos on the PC using my nice HD display, its really not as bad as it looks on the phone.

I think it could be just the app itself and how it was written. But also adjusting the brightness can usually help. One reason I hate the pentile display. > <

I think it is being caused by 2 things.
1. Automatic brightness.
2. Settings -> Display -> Auto adjust screen power. (Although I thought this setting never worked, it sounds like the exact problem you're having)
I just use a brightness widget and a scroll of the top status bar to adjust my brightness all the time. The automatic brightness is pretty much unusable because I find it too dark most of the time.

i've turned off the auto adjust, but i still have general auto brightness turned on. Still dims when in the gallery. i've noticed this on every skyrocket phone i've ran into, the pictures just look dark and dull when being viewed in the gallery.

Turn auto brightness off, this is the main reason I turned mine off. It will usually turn it to the lowest brightness in galleries and looks like ****. Auto brightness is garbage from the factory. There's suppose to be a better mod that checks nearly 100 times a sec and uses less power but I been too lazy to ask my friend for the name of it lol.

There's a post in q& a somewhere that explains the iso settings in different lighting environments. I usually just keep mine set to 200 and makes it alot better. Still darkens a little bit but not near as bad as it did before. I also noticed a difference turning the flash off.

The topic more or less was on the gallery view, not the actual camera quality. It takes pretty decent photos compared to what else is available.

Something ia weird with the ICS update

The ICS update messed sth up with the video playback, when watching a video from either youtube app or gallery the screen brightness drops down if u turn the device in landscape mode (notice that i have ensured tht auto brightness is OFF)
Anybody elese?

No issues on any of the custom roms I've tried.

hm.. srange issue. I didn't noticed any of this while watching videos..

Happened to me today while whatching a video with MX Player. But nothing in Youtube app.
Also another backlight bug: I have my backlight set at 2/3. After I exit camera it doesb't go back to 2/3, it stays at 100%. If I try to set it back from the Sense widget it just acts weird. A lock/unlock does the trick.

the whole ICS thing is weird, Go Launcher went nuts and keeps freezing, Android Widgets PRO doesnt work, battery is dry in no time, cant catch any radio station anymore, mobile podcast doesnt work, contract groups duplicated, this ICS is acting hilarious ... at least by me

Yeah, tried stock ICS in unrooted ROM. The backlight will suddenly brighten up on me.

Stock Sense based ROMs have a few bugs with autobrigtness. This bug has existed since this device ran gingerbread.

Did you check whether you cover the light sensor with your hand while in landscape watching videos?
Edit: you said you do not have autobrightness...sorry :banghead:

This is a feature, not a bug. It becomes a bug if/when it turn automatic brightness to full brightness and you have to re-set it on automatic in settings like it often happened on GB. Didn't notice this on ICS (ROM in my signature) 'til now.

When I was using GB, brightness turned to 100% when I opened camera and went back to my setting when I closed it.
Same thing in ICS except it goes back to my setting only when I lock/unlock the phone.
But the brightness turning to 100% when I pen the camera isn't a bug. It's supposed to do this. Not going back to my setting is a bug.

On both gingerbread and ICS builds it would not revert back to the previous brightness level for me. I was experiencing a bug. I KNOW it is supposed to crank up the brightness on certain applications. NOT reverting the brightness back is what was happening.

I'm experiencing exactly the same thing as the first poster. After the update, video playback will lose brightness and colour contrast and then magically "pop" back when I try to reset the brightness (even though it still shows as maximum, i.e. dropping brightness from an indicated 100% to 99% will cause it to become brighter!). I emailed MoboPlayer to ask them whether it was something wrong with their ICS implementation before realizing that it was happening on every player.
It's really annoying! (Maybe it's time to CyanogenMod it ...)
Stace.

I have experienced this with ALL ICS ROMS. Sometimes is happens, and sometimes it doesn't. Only bug I have in ARHD.
