[Q] Light sensor issue on Android 3.1?

I updated my Xoomto 3.1 right after unboxing it. Then I found that its light sensor does not work.
Setting screen brightness to auto has no effect, it just keep the same brightness regardless of ambient light. So I must set the brightness manually, it is very annoying.
I installed some sensor utilities such as AndroSensor, Light Sensor,... but they don't display any value (just "waiting for event").
Does anyone meet the same problem? Is this an error in the sensor or a bug of Android 3.1?
(My Xoom is CDMA version)

Yeah I noticed the same thing the other day. Auto does nothing.

Could you give more details?
Did it work before upgrading? How is it now?

I'm not sure if it was doing it with 3.0, just noticed mine the other day.

Same here...

I have no light sensor issue--before or since the update.

I downloaded a sensor app and confirmed that i have no light sensor readings. I'm jusrt not sure when it happened or if it ever worked. could it be a kernel thing?

Thank you all for your replies.

What do you mean? Does it work or not on your Xoom?
Anyway, as I see, this is not a common issue, so I returned my Xoom.

Actually I take it back, the auto brightness is working for me

I didn't even notice mine wasn't working until this thread. I'm just going to go with it.

so this is weird. I upgraded to the new Tiamat kernel today and my light sensor is working again. It must be a kernel thing. I'll post a message in that thread.

Don`t have this issue myself, try a data factory reset if all else fails that may help sometimes. Otherwise it might be a hardware issue. Do you also see these stripes with full brightness in apps like YouTube e.g?

when i use youtube, if i maximize the brightness, youtube slow down and then apper the stripes...
should i reset?

Just tried YouTube on full brightess and had no slowdowns whatsoever or any visible stripes. Try a factory reset and if that doesn`t help there may be a problem with the graphics gpu and i would return it asap.

thanks mate!

Does it only show stripes on specific colors?
I had this on my GNex...where i could see this stationary stripes with red or blue at high brightnes settings. Stationary means, that the stripes didnt move even when i was scrolling a red/blue image.
As this is most probably a hardware issue, i send it back to samsung and they replaced the screen...
cheers
Flo

probably is an hardware issue.
the problem is that i live in Italy, and the moto g come from amazon.co.uk... what i should do? contact amazon or motorola?

Mine has the same "issue", visibile only very close on medium-high brightness, it is a glass feature (as the weird reflections visibile on sunlight) and not a display problem, i think.
PS: I live in Italy and i bought the phone on amazon uk too.

[Q] Missing sensors in Nexus 5 after install Android 5.0

Hello,
After clean install Android 5.0 on Nexus 5 I have lost all sensors.
Do you have similar problem?
Is there any solution to fix it?

What app are you using? This looks like a bug in an app, than in Android itself.

I had this problem even before installed any apps. In android l developer preview I didn't have sensors also, so after installed final version of lollipop the first thing I made was check sensors. On kitkat everything worked perfect.
Wysłane z mojego Nexus 5 przy użyciu Tapatalka

i don't have light and proximity sensors too...
i did full wipe and flash stock OTA
hope they will fix it soon

Since upgrading to Lollipop my proximity and light sensor also stops working after a few minutes. It works again after a restart, but only for a few minutes.
I have flashed 4.4.4 again and the problem is not present there. After upgrading to 5.0 again the problem came back.

the apps are the issue here gentlemen.
1.On call as you bring your phone to ear, screen turns off?Proximity working
2.Adaptive brightness enable and use the phone on same brightness settings in bright and dim areas, screen brightness intensity change?Light sensor working.
3.Screen rotates views?Accelerometer working.
4.Play asphalt or any other motion requiring game, car turns?Gyro working.
5.Open maps, get pointing direction?compass working.
6.Use pedometer, counter change?step counter working.

No sir, it's definitely not the apps in my case. After a restart the light and proximity sensors work as expected, but a few minutes later they stop working. I could confirm this with the Sensor Box app as well as with no's 1&2 in your post.
I noticed it first because my adaptive brightness did not work and the screen did not switch of in call. I only installed Sensor Box to see if the sensors still work, this confirmed that they actually stop working and that it is not a calibration issue because Sensor Box shows no reading from these sensors.
This is definitely an issue with Lollipop because I flashed 4.4.4 again and everything worked fine confirming that it is not hardware, but after once again upgrading to 5.0 the sensors stop working few minutes after the phone starts up.

That's interesting, have you tried any other custom roms or kernels based on lollipop? I know that is a long shot or even that best advice but could you, or have you checked on other roms?
SO only your Proximity and light sensor the issue? Or all the other sensors a bust?

I haven't tried any other Lollipop ROMs, I thought about it and I might actually give it a go to see if the problem persists on other ROMs as well, but I would prefer to have stock Android running on my phone, so I'm really hoping for a fix from Google. I'm on few other threads about the same issue, so I know there's a lot of people with the same problem. I had this on the dev preview as well.

I have tried Code-Blue kernel as I have heard it's a good one, but the problem is still there. I might try a different ROM in the near future.
For me it is only the Light and Proximity sensors, all other sensors work 100%

The Same Problem For Me As Well, My Light Sensor & Proximity Sensor Arent Working. I have downloaded the Final Image from Google Website for 5.0 hammerhead. But still the problem persists.
Nyk

After I got the Play services (with secure locations) update two days ago my light and proximity sensors are gone too. They will work for a while after reboot, but eventually they die.
All other sensors are working fine and only other updates have been to Skype, SwiftKey and TuneIn Radio.
Edit: I'm on stock OTA, no root and never unlocked the bootloader.

So uninstalling the play services update resolve the issue? I'm back to KitKat as without light sensor I find uncomfortable to use the phone. Will await the fix before moving to lollipop..

"Clean install" using factory images? I did, no issues here.

It seems to be working until I get a phone call, after that the sensors will die.
Have uninstalled the Play services update now and the phone has been up and working 100% for a little more than 4 hours now. Will try to make a phone call to see if it still works after that.

Uninstalling Play Services and Play Store update made no difference here. Problem still persists.

Hi I have the same problems . Sensors are working after restarting my phone random time. Also you can read here

Uninstalling Play services didn't do it for me either. Sensors work for approximately 4-5 hours then they die.

Installed Play services update again after a few days and now my phone has been running fine for 50 hours with all sensors working 100%.

Weird? Brightness randomly adjusts all the way down when auto brightness is enabled

Anyone else notice their Honor 8 automatically moving the brightness slider all the way down? The screen goes very dim. I move the slider back to the middle and it moves back down, thus dimming the screen. I see a thread on Honor website that has received no constructive response: https://club-us.hihonor.com/honor8.32/honor-8-feedback.1226
Another question. What is the best way to let the Huawei developers/support know about issues? Thank You in advance.

It is a known auto brightness bug and as far as I know it is going to be fixed or at least it is going to work better with the update B131 which is coming soon.
From the changelog: "Optimized the auto screen brightness feature." link: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1276/g104/v63548/f1/full/changelog.xml

Well, the C00B160/163 sais "Optimize brightness adjustment algorithm." as well http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1288/g88/v63967/f1/full/changelog.xml
so the Honor seems to be aware of the problem and in England sby just got the B131 on his phone therefore you will get the fix soon

Great! That's good to know. Duly noted. [ns]

Not sure if that fix is included in B150 for FRD-L04...

Listed in the FRD-L04's update notes it says something about optimization or fixes to the auto-brightness setting. I've turned it on since and the screen doesn't immediately drop to minimum brightness outside a well lit room or direct sunlight anymore. I wouldn't say it's perfect now, but I more often find myself turning the brightness further down a bit as its brighter than I need it to be to read it easily when I'm not somewhere that's pretty dark.
I may have just also gotten more used to the lowest setting so it bothers me less. Or the lowest setting may actually be a bit higher? I'm not sure really.

I have the latest L04 update and when transitioning to darker area at night the screen goes almost too dark.

I think this is a bug that been around Huawei phones for some time. Somehow some have it and it gets fixed over time.
But DO factory reset after the update.

Just got my FRD-L09 which was on B101 and has just taken two OTA's to B131 but this auto brightness bug is still present. I factory reset following the update but still find if I use auto brightness it will dim to the lowest setting after about half an hour without any change in the ambient lighting. Do I have a hardware problem and need to ask for a replacement? Thanks

Just thought I'd update on this. I had tried to register for the Nougat Beta test program but didn't seem to get anywhere with it so was about to call CS to try and sort out this issue. Woke this morning to find my phone had downloaded B316 (Nougat) and was prompting me to install which I now have. Auto brightness now seems to be working like a charm and no other issues that I'm aware of so all good now.

Minimum brightness issue fixed.
Hey guys,
I got the phone 3 days ago and i was facing the same problem on up to date software (B162) for FRD-L04. After trying out a lot of different things suggested online, i was messing around with settings and i have successfully fixed it. It's been a whole day and I've gone from pitch dark to sunlight and the brightness hasn't adjusted itself to all the way down yet.
1) Go into Developer Options and turn off the sun light visibility option.
2) in the notification tray select auto brightness checkbox and then make sure you are in a pitch dark room or have your light sensor covered and wait for the brightness to go all the way down.
3) Now adjust it to the minimum brightness setting you like to keep.
4) Test it out in bright and dark environments and it should be all good. Restart your phone just in case.
Enjoy!

Am i the only one who has display backlight flickering with my Zenfone 6?

Hi,
i got my Zenfone 6 today, and i really like it, but there is one thing that probably makes me return it...
The display is flickering when it‘s set to really low brightness, i think its the backlight.
I‘m not sure if it's broken or not. So, am i the only one with a flickering display?
Thank you

I had the same situation yesterday, it was on low brightness too.
But only for a few seconds, for now, everything seems fine, even in low brightness.

With adaptive brightness set on or off?
Do you have the latest firmware version WW-16.1210.1904.133?

It doesn‘t matterif adaptive brightness is on or off, it does it as soon as the display lowers its brightness to the 1st 1/4 of the brightness bar...

Ok. Do you have the latest firmware version WW-16.1210.1904.133?

Hi, i have the same problem. Received the phone a week ago and trying to find a solution. I am on the last firmware, tried the dev option about overlay, hard reset and still the same. Going to send it back to Asus for a refund...
I wonder if this is software or hardware related. As of now i can't use it at night with low brightness.

It will probably be a problem for a particular phone, I would recommend that you replace it with a new one.
https://swedroid.se/forum/threads/snabba-fragor-snabba-svar-zenfone-6.165775/page-38#post-2443073

Thanks for the feedback. Called Asus this morning to replace it hopefully.

My Zenfone 6 does the same. If I set the adaptive brightness on the low brightness flickering disappears. I think it's a software related problem because others Zenfone have the same behaviour.

Tried it. No matter the settings it flickers. I found a video that match the problem, weird no one noticed : youtu.be/DN1La8AbZsI
Check at 1.16 min, on the right side, it flickers like that, when the luminosity is low. This is what i see on my screen.

Same here. White backgrounds flicker when brightness set to low. Tried disabling HW overlay, but it didn't help. Phone on the latest firmware WW_16.1210.1904.133.

Anybody letting the techs at Asus know about these problems? I would like to hear about a fix before I buy anything.

I am in touch with Asus France, i have to send back the phone for an exchange as they told me it MAY be a hardware problem.
I linked the thread to them if it can help.

Every zenfone I have had (2 and 3) have had this issue.

I think it's a software issue...if you let the brightness working in auto mode the problem disappears.

It is set in auto mode on my device and still the same. With or without doesn't help sadly.

Hmmm is this international version? The U.S is coming next month. Hopefully this get fix before I'm buying it.

Mine is flickering when brightness is set to low (about 1/4-th of the brightness slider and down) no matter auto or no auto.

Funny how we here in the US complain that so many phones are released in the EU, or India, or China long before they ever appear here....but in reality it could be that we benefit from this practice so that some of these issues can be resolved by others before we have to deal with them.

I hope that when this phone is released in your country, this issue will be solved definitively via software update. The way I see it, this problem isn't a huge problem, fortunately. Actually the screen flickering occours only if the brightness is set to a very low level (e.g. <20%) but, with this setting, the backlight is too dim as well for use even in a dark room (obviously for my taste). Since I use adaptive brightness with default settings, the minimum value the screen brightness reaches is 34% so I never get the problem....
