Auto-brightness switch has disappeared?

So...this is kind of weird. I went into the Wallpapers & Brightness settings to adjust the brightness of my screen and there's no auto-brightness switch. I actually really like the auto-brightness. Constantly adjusting it manually is kind of a pain -- especially if I'm running and my phone is in my armband.
I tried resetting the settings and I just restored my phone. The switch is still gone.
Has anyone else enountered this? Is there something obvious I'm missing? That switch should be there, right?
I have an iPhone 5.
Thanks in advance...

Hello Geoffery Stone,
Thank you for using Apple Support Communities!
I want to recommend backing up your phone to iTunes and restore the device, but this time, rather than restoring from a backup, setup the phone as new and see if the switch is there.
iOS: How to back up and restore your content
http://support.apple.com/kb/HT1766
If it is, then restore from your backup. If the switch goes away, then either an app, or a setting is removing it.
If it is a setting, then resetting all your settins should fix it:
Reset iPhone settings. Go to Settings > General > Reset, then choose an option:
Reset All Settings: All your preferences and settings are reset.

Auto Brightness & battery life iPad 2

Hi
I got my iPad 2 about a month ago and ive noticed that the battery life varies quite a lot, and seen many people complain on forums that its poor/worse than ipad 1 etc.
I suspected that the auto-brightness feature was the culprit so i did some tests, watching video:
Auto OFF, Bright room, 50% on slider     10% = 66 minutes
Auto ON, bright room, 50% on slider         10% = 51 minutes
Auto ON, dark room, 50% on slider          10% = 71 minutes
Obviously whats going on here is that the auto brightness (AB) is brightening up the screen in a bright room, and dimming in darker environments. But i didnt expect such a difference in battery life!!
I also ran the test just idling at home screen:
Auto ON, Very bright room, 50% slider     10% = 39 minutes
Auto OFF, Very bright room, 30% slider    10% = 82 minutes
So basically, I feel people who are experiencing dissapointing battery life are perhaps using the ipad 2 in brighter conditions more, because these tests show it can be literally half the battery life in a very bright room near a window etc
They also show that at a certain brightness the life is very good, even up to 13hrs or more! Good to know if you need a lot of life you can just turn AB off and lower brightness and get 14 hours LOL
Any thoughts?

It really depends on what you are doing. If you are playing graphics intensive games for several hours, you may find that battery life is a bit shorter than if you are surfing or playing movies.
What are you doing generally and how long is you battery lasting? There is a small chance that your battery is defective but without more information it is tough to tell.
There are also occasional bugs in the iPad OS that will drain the battery faster than normal. I've found that when it seems the battery is draining too quickly that restarting the iPad helps. Hold down the power button on the top edge of the iPad for several seconds until you get the slider, slide it off. When the iPad is off (the spinner disappears) you can turn it back on by holding down the same button for a second or two.

Brightness slider on iphone 5 doesn't work (NOT auto-brightness)

With Auto brightness switched off, sliding the brightness bar from left to right brings little or no change in the brightness of the screen. The screen is always in highest brightness. IT flickers sometimes to a lower brightness but strangly if I shake the phone or tap the brightness changes and comes back to very bright.
Not seen anyone raise this issue. I think there is a hardware defect with gyro someway afffecting the level of brighntness. I could be wrong. Has anyone else seen this issue before ?

I turned to the service provider, they did everything they could. I inserted my simkarty in another Iphone 5 and everything worked well. Today I changed the operator and the problem remained. All operators in our city supports 3G and my previous Iphone 5 worked in the network. Maybe the problem is with the defective module 3G?!

I have an iPad 1st generation that no longer has working volume buttons but every once in a while the sound turns on. So I know the speakers still work. I have tried resetting all settings and made sure that my side switch was auto lock not auto mute.

I have tried resetting all settings and made sure that my side switch was auto lock not auto mute. I have tried the mystical swiping upward on the screen with 4 fingers to get some special sound menu (which I never succeeded in getting). My headphone jack doesn't work all the time either so some times my kids can hear their games and sometimes they can't. I am super frustrated at this point. So any suggestions would be great. Am I missing something basic or do we just have a soundless iPad now?

Why does auto brightness has a bug in iOS 7.1.1 . The brightness switches automatically to higher in bright places but not returns to lower brightness in dark places but when you lock and unlock it becomes normal

Hello,
Same problem for me. Really a pain in the *** this bug ! Does Apple fixed it. I'm really suprised noone reports this problem and apple does not adress this.
Because of that, I cannot give it anymore to children because it hurts the view. Really a shame on the part of apple !

When I turn on my iPad the grey 'brightness slider' is in the centre of the screen and I can't get rid of it. I've tried switching on / off 'auto-brightness' in 'settings' but it won't go away. What am I doing wrong? Any advice gratefully received.

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive (CD/DVD drive) and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

Since upgrading to Lion the screen auto brightness adjusting icon comes on allmost all the time even though i've switched it of in preferences?? it's so annoying..any ideas??

I don't know exactly what the issue is, but I think I do. Are you talking about what happens when you start up your MBP, full brightness, with power cable in - and when you're using battery only, the brightness dims? If so, this is a feature designed to make sure your monitor is bright enough while using batteries - but not so bright as to cause an undue drain on power.
I don't know about a cure to this issue, if indeed this is what you're talking about.

Auto brightness button disappeared.

Suddently, the auto brightness on-off button disappeared from the menu. Anyone experiencing the same problem? Is there any software method to fix this?

iOS 6.0.1 iPhone 4

Auto-Brightness Toggle disappeared?

So I have been having the issue some are experiencing with the brightness of the screen not working the same as within iOS 5. I have the problem where it seems to be working on the reverse process. When it is bright out, the screen goes darker, and when I'm in a dark room, the screen goes almost to full brightness.
When I went into settings to turn auto-brightness off, the toggle is not there any longer. ???? Completely confused. I am also having the issue with the phone crashing and displaying the fuzzy/pixelated vertical lines and then the screen slow fades to black and then reboots itself. I took it into the Apple Store on Saturday to discuss some other issues that I had and they completely restored my phone, and told me not to use any of my restore files in case of corruption. So here I am, confused, lol. Anyone having similar issues?

I got the same problem! The auto brightness toggle is not there any more. A full restore did not help! Tried everything! How is this even possible? Software glich or harware? The proximity sensor also does not work! Anyone?

Auto brightness- press settings - brightness

No auto brightness, pressing settings - brightness & wallpaper there is a brightness scroll bar but the box underneath saying auto brightness has gone. It was there before!!!
The box was there after updates.

The level you set in automatic brightness is the minimum level the display will go to when the phone is turned on, assuming you are in total darkness.
It will then auto adjust UPWARDS ONLY when you go into brighter environments, however the amount of adjustment is limited, so if you want to be able to achieve maximum brightness in bright sunlight, you would need to set the level fairly high to begin with.
It will not adjust downwards if you then go into a dark environment, at least in my experience. Others have said it does after a minute or so, but if I switch on my phone in he middle of the night or in a cinema etc. I don't wait a minute to see if it will dim, I do it manually.

Does anyone have auto brightness problem?

hi
I just got an ipod touch replacement yesterday and i just realize my auto brightness setting is weird. Because sometime when i drag the on button but the auto brightness is off. But when i drag the off button the auto brightness is on. do u guys think is the softwear problem or hardwear problem? Also do u guys think that i should go back to bestbuy and exchange it?

I can confirm the auto-brightness works on my 5th week iPod Touch 32GB.
I've run some experiments and I think I've got it covered right now. Let me explain.
First of all the slider has to be the minimum brightness this is the amount of brightness you start with when you unsleep/powerup your device. This is easy to test and verify because if you push the slider to the outer left and you put your device into sleep and wake it again (in a dark room) then you'll have a very dim screen; with the lowest possible brightness setting. I then turned on my strong desk light and after approximately 1 second an amount of brightness kicked in to compensate for the extra light shining directly at my ipod.
I can also confirm that it doesn't work backwards, because when I turned off my desk light, the previously added brightness did not go away. My iPod didn't revert to the very dim screen. But when I put my ipod to sleep and wake it yet again (with desk light turned off) I had yet again the very dimmed screen. So it can be confirmed that, at least on my device, putting the device to sleep and wake will trigger the ambi light sensor.
Secondly I've put the slider to approximately 1/6th of a full bar; I find 1/6th of a bar a perfect minimal brightness setting for use in a dark room. So yet again I've put my iPod to sleep in a dark room. After waking it up it launched with 1/6th of brightness level. Then I switched on my strong desk light again and after approximately 2/3 seconds this time it added more brightness to compensate for the light.
In both situations I don't know exactly how much brightness there was added but I think it's percentage based on the amount there has to be compensated for the extra light source that's shining directly on the iPod.
For a final test I've put the slider to like 5/6th, which is a very bright setting, totally not necessary to have as a minimal brightness setting but let's use it for this test. Put iPod to sleep, wake it up again (yet again a dark room). The iPod launches with a very bright screen now (5/6th of its capacity). Now let's shine the desk light again directly onto the iPod. This time it enhanced the brightness a tiny little bit, almost unnoticeable. But it did compensate a little bit for the extra light. It only has to compensate for a little bit anyways because the minimal brightness level was already set to 5/6th of the bar.
So to conclude:
* auto-brightness on iPod Touch 32GB works
* the slider is used to set the minimal brightness level
* brightness compensation kicks in at roughly 1-3 seconds after you've awaken the iPod and is under the influence of a strong light source
* after auto-brightness compensated the brightness it will not revert to a more dimmed screen unless you put the ipod to sleep again and wake it up
I hope this clears things up for all those who are having doubts.

Auto brightness not working -new screen protector or 4.0.2 to blame?

Hi there,
I recently bought a couple of new cases for my ipod touch (latest gen 64gb.
They both came with a 'free' screen protector, one of which I have applied, can't recall which case it came with though. (and I'm not sure that matters anyway?)
Since I applied the new screen protector I don't seem to have auto brightness any more.It is there, in the settings screen. But it doesn't seem to be working.
I've tried switching it (the setting) on and off, turning the ipod off.
I applied the protector around the same time that I updated to 4.0.2 (8A400) - I may have done the update. I 'think' I udated the unit the day before but I cannot really recall. I don't remember on what day I did which change so can't say what is causing this error.
Is anyone else getting auto brightness errors after going up to 4.0.2?
Is this kind of issue common with some screen protectors?
New ipod user - never had an apple anything before this - had it about 2 months.
Suggestions are GO

This morning, I updated to iOS4.0.2. I went to sleep with Pandora on (I work midnight shift) and when I awoke, I switched to mail and lost the music. Verified it wouldn't stay on and proceeded to do a hard reset (held down on/off switch and home button simultaneously well over ten seconds (( apple came on and then went blank/off again ))). Turned my iPhone 3GS on again and problem was gone. Hope this helps you too.

Have you tried a reboot of the iPhone? Hold both the power and home buttons until the apple logo appears and it restarts, ignoring the red slider if it appears.
My iPhone went to full brightness all the time after updating to iOS 6.1.3. A reboot seems to have helped make it work as it should. Also check Settings > Brightness and Wallpaper and see how it is set, reduce the brightness level it is too bright for you.
