I only noticed today, but with adaptive brightness on, the brightness slider in the quick settings pulldown menu does absolutely nothing. Brightness always stays the same (too high).
So I went ahead and tested some light meter apps as well as lux dash from the play store and all report maximum brightness (20000 lux) at all times.
Does the Pixel C not have an ambient light sensor (as advertised) or is mine simply broken?
Any input greatly appreciated.
Have nice holidays everybody.
It actually has two on either side of the front facing camera, if you shine a bright light and look at an angle you can see them.
Sounds like yours is broken.

I think it's broken. I have the same problem. Neither light, nor proximity sensors work. I installed a sensor testing app ("sensor sense")
and though it shows the sensors specs, there is no data on either of the two sensors.

Thanks. That is what I feared. I will get it replaced.
Btw. does your Pixel C have a working compass. I know, there is no GPS, but on the Google Play Store it says "compass". Although mine never worked.
Off to a bad start with an otherwise awesome tablet.
I had this problem too, but I fixed it by clearing app cache in Android settings then clearing cache from recovery. The slider worked after that.
i've read the back cover is magnetized. i've seen a photo of the device stuck to a refrigerator like one of those door magnets. so i have a difficult time accepting that any compass would work right.

I only had to clean the cache in android settings, than a simple restart solved the problem.

Hey guys,
hope someone can help me.
I've the feeling that my light sensor might be damaged.
The setting is on automatic light regulation and i've the feeling that the
screen is very dark. Is there any possiblity to check if the light sensor still works fine?
I've already put my finger for a few seconds on it and nothing changes.
I also read in the guide that the screen should wake up when you wipe over the switched off device.
Unfortunately nothing happens when i do so.
Thanks a lot for your support

Autobrightness has been too dark since the S2. The S3 also suffers from that bug as does the Note 2. Unless Samsung fixes it with a update you`ll have to wait for a hack and root the phone to be able to change it.

Thanks a lot for this information. I didn't know this, as it's my first Samsung mobile.
But my impression is that it worked fine, and unfortunately the note 2 fell down at weekend and
now i've the feeling that the regulation is not correct since then. Is there any test to try if the light sensor still works?
And normally the switched off screen should wake up when i swipe over the screen, right? Because it doesn't work, or is it necessary to set up some settings?
Thanks a lot again for the help!

I think there's a light sensor test in the service menu (can't remember the dialer code to access it though) and for the phone to wake when you swipe over the screen you need to enable "Quick Glance" in Settings > Motion

Hi, does anybody have issues with light sensor/auto brightness on Nexus 4?
Sometimes mine stops working and brightness does not change with light variations.
Rebooting solves the problem.
I am running PA 4.5 beta 2 with stock kernel, but it happened sometimes also on stock rom.
Thanks!

Shouldn't be a problem with PA, I'm running it with no problems.
Maybe you have dirt over your sensor or maybe a thick screen guard over it?

Try searching google for the lux auto brightness apk. Install this and let it take control of your auto brightness. See how it is. Make sure you download the full version.
I just got the Tab S 8.4 yesterday and I am trying to figure if I am missing something. My screen will not rotate, it will stay in portrait mode all the time, it will not go to landscape mode on anything...youtube, internet, gallery, etc. Yes...the SCREEN ROTATION is on in settings. I have turned it on and off and still nothing. I even went ahead and did a reset. Still nothing.
Am I missing something?
Probably not, just need to return it. Something might be wrong with its hardware or software that will not make the screen rotate.
Is screen rotation highlighted when you pull down the notification panel? If it is download SENSOR BOX FOR ANDROID from play and see if the orientation sensor is working.

Screen Rotation is highlighted when I pull down the notification panel. I will download the app and check it out. I mean, what can I do anyways if it does show that the sensor is working correctly?
Are you using a different launcher?

at least you will know the hardware is working. You could also try SET ORIENTATION from play to see if you can force it.

Set orientation did work. It did change the orientation of the screen from portrait to landscape. But it stood that way, meaning everything was either going to be stuck in portrait mode or landscape.
As for the launcher...its stock touchwiz. I have not tried any other launchers.
What was the result of the sensor test?

im not home with the tablet yet. All those things I did yesterday night. I will try the sensor test first thing when i get home.
Ok, I downloaded app and no good. The gyroscope sensor did not move correctly. The accelerometer sensor showed me the worse. The ball just rolled to the top right corner and stood there. Did not move at all, even when I slam down on any direction. Returning this tablet.
Thanks everyone.

I bought an Open Box for about $90 off from Best Buy, the 10.5 Tab S, and had the same issue with no rotation of screen. I only tested it with other programs that will change orientation for you, and it worked then, but not automatically, only when using the app. I checked all settings, including accessibility, I flushed the cache using the Recovery mode, but no luck. I did get lucky though at Best Buy, as they were awesome and ended up giving me a brand new one in exchange, without any additional charge. There may be some manufacturing defects in the sensors that are causing these issues. Good luck to you too sir.
Ive seen it said that some people, who've had the same problem, gave the tablet a sharp slap on the back to fix it.

My Samsung Galaxy Tab S 10.5 just exhibited the same problem today. A sharp slap to the back of the tablet did fix it...
Thanks.
i know this thread is 1 year old however i purchased a brand new S2 8 inch tablet from canada computers and it too will not rotate the screen on its own. If i use a 3rd party software it has no issues rotating but it stays that way until i rotate it otherwise manually. Brand new less than 1 day old and i already have to warranty it with Samsung disappointed that such a premium tablet having an issue out of the box. Also all sensor software in install all indicate there are no sensors installed.
Edit: ok now everything works great and all sensors work now on Sensor Box. I had to do a hard cache reset of the cache partition using that dos look alike menu at startup.

This confuses me since the Android settings Backup / Restore has "Factory Reset" which I did twice and it didn't work, then I pressed power button, volume up and home button to bring up the other menu on bootup and selected the format cache partition option. This resolved the issue and was happy I didn't loose my data unlike the backup/restore had wiped all my data. Is that still considered a factory reset? I did see the option to factory reset but didn't select it, I opted to try the cache partition instead which I was glad had worked. Saved me from taking my new unit back to be repaired.
theres an app called bubble level (spirit level) i used to re-calibrate my sensor since there isn't a built in way anymore, if the slapping doesn't work or you don't wanna risk it try that.
Maybe it is just me and my device, but since the MM update (the real one, not the beta) my notification LED doesn't work. I have tested it with text messages, emails, missed calls, charger plugged into my computer, charging plugged into a standard charger, and charging plugged into the fast charger... nada on any of them.
Anyone having this issue? If so how have you rectified it? It has been a minute since I first got this thing (got it at launch) and the MM update reset all my settings so maybe there is a setting to turn it back on I am missing?
Help out a brother if you can. Thanks.
OK, so does anyone have any suggestions for an app that might help by letting me manually setup the notification LED?

If you haven't already, try a factory reset first

Actually yes. After I wiped my phone for my wife the notification now works.
Another issue that I recently found the solution to... if your ZF2's proximity sensor has gotten crazy sensitive since the update try cleaning it. Seriously. Especially if you have a tempered glass screen protector. I thought the piece of advice was bogus but I cracked out my lens cleaning spray and cloth and BOOM, the proximity sensor works correctly again.

Thanks! Got the led working again after a factory reset.
By the proximity sensor do you mean the little one next to the selfie camera or the GPS?
After a lot of fixed I've got the ZF2 working fine, except for the "smartlock - safe places" that thing can never work right.

Sorry, I just realized that you had replied.
Yes, the one beside the camera. Many have had an issue where the screen goes black after you start or answer a call, especially after the update. It seems the update made the proximity sensor much more sensitive. Since all decent screen protectors have a small cutout for the proximity sensor it will tend to accumulate dirt and oil from your skin. Wiping it down doesn't seem to get it clean enough for the sensor so you have to get a little more aggressive to clear the problem up. I went months enduring the problem and even set my phone so I could disconnect from calls using the power button and then ended up stumbling over the solution when setting up the phone for my wife when I upgraded to my Axon 7.
No led indicator
Hi i've been experiencing the same issue. After I update my zenfone 2 ZE551ML 4gb/64gb version, I have noticed that the led incator is not working and it is not found in the settings. Also, another issue I have encountered is that quick charging feature is not working sometimes but sometimes it works. I don't know how to fix. I'd be glad if someone could help with a step by step process. Thanks in advance!
When I'm in a very bright environment (eg outdoors, sunny day), I can't manually adjust the brightness if auto brightness is on. But I can do it if the brightness slider is not on "red' (if it's not too bright outside). On manual everything works ok, if it's not too bright outside everything works ok.
It wasn't like this on my S7. It bothers me when using Waze: I would like to manually override the auto brightness and adjust it by just moving the slider, not having to turn auto brightness off.
Anyone else having this problem?

I am having problems with my SM-G965F. My brightness auto adjusts with auto brightness turned off! There is definitely something screwy going on with the auto brightness. After a while, it gets so I can't adjust it at all. That is, I can move the slider full left and right and nothing changes. It doesn't matter is auto brightness is turned on or not. No change.
I have done a factory reset once to clear it but the problem came back. They have this usage memory feature and that may be part of the problem. I found this post on re-calibration of the brightness sensor to be helpful:

I did this and I got the display brightness back into a reasonable range. However, I can no longer turn auto brightness off at all. very weird.

UPDATE: Today Samsung released an update to the Samsung Experience Service that seems to have completely solved my auto-brightness issues. Prior to that, I was using Lux Lite and that was working well. If problems come back, I will use that again.

Not sure if they are doing a slow rollout or if it is region based. There are some posters who say that when they search the galaxy store, nothing comes up. When I search it, nothing comes up. I have an international version (unlocked). This device was apparently destined to go to Thailand. But one thing is for sure, Samsung fixed the brightness bug but maybe your carrier is holding it up?

Well, it was working fine until I rebooted. Now the auto-brightness doesn't work again just like before. So, unfortunately, back to Lux Lite. I have to say, that the auto-brightness issue and the battery life of this phone suck.
