hi
As soon as i make a phone call my screen goes off, now on my iphone it used to do this only when the light sensor was covered. to bringthe screen back on I have to press one of the black buttons in the bottom of the phone, is this a fault?
I had this problem after fitting a screen protector. removing it solved the issue for me.
The genuine HTC Screen protectors have 2 holes in for the sensors. I can confirm this does not affect the screen when making a call.
Are you using a screen protector which doesn't have a hole for the proximity sensor etc?
It may be it can't function right as it maybe seeing the protector as something close to the sensor, hence why the screen goes off.
I have a Vidocq screen protection and the phone wake up again when I finish the call...
I dont know if this is an issue with other handsets.
I installed proximity screen off application . The purpose was to have the phone turn the screen off when i close my flip case.
However i found something strange.
When the flip case is very close to the screen the proximity sensor does not seem to detect that there is something covering it.
Is this an issue with every one ?
Any solution
Please see the videos
As you can see from the videos when i bring the shield very close the proximity sensor does not seem to detect the sheild.
Edit : However if u use ur finger this is not seen
I've noticed the same behavior, it's quite annoying because it kills one of NoLed's best features (screen off using prox. sensor).

Still really annoying that the original flip cover won't work with the proximity sensor. A workaround might be a third party flip case. A diy modification of to the original one won't work since if I close it AND hold whatever object that alone is enough for a positive result over the flip cover, the sensor will still not register positive [because a minimal distance between an object and the glass surface is required, see below].
mine works even with a finger...
I've done it a few times accidently when i was trying to access the notification bar while on the phone

Thats the thing i was saying.
With finger i works great even if u touching the screen
Dial *#0*# and press sensor. If it vibrates, the proximity sensor is registering an object.
Maybe it comes in handy with testing.
It's working for me, thanks for the tip about the app!
edit:
Okay, I tested and found that indeed when you set the app to:
"Cover an hold to lock the screen" to say 5 seconds.
Close the flipcover.
It does not register.
However. If I set:
"Disable Accidental Lock" to .25 seconds.
Close the flipcover.
It works quite well.
Coming back to the sensor. It indeed does not register the flipcover when it's closed and touching the screen.
Weird thing is it does not register your hand anymore either.
Recreating issue:
Remove flipcover and lay it completely flat over the sensor.
Dial *#0*#.
Press "Sensor".
No registration.
Now hover your hand over where the proximity sensor is, and... How about that, no registration.
This indeed messes up NoLed's battery saving feature.
This can also be a problem when:
You set screen timeout to 10 min.
In the app's settings set "Disable in landscape" to on.
Then use an app in landscape mode.
Close flipcover while in landscape mode.
Then rotate to portrait. At this point it should start registering again and turn off screen..
The sensor does not register and screen stays on.
Drains battery.
It is a really cool idea, but it does not function properly.
It's too flaky, also when just handling your phone. I find myself accidentally turning off the screen.
Maybe if you use a case or some other cover with a different or thicker material it would work better.
I ordered a Zenuscase, I'll give it a try with that one.
Don't know how long it'll take to arrive though
reflective color
heey i found the problem , the sensor is working fine ... but when so close with any black object the light is not reflected back to the proximity sensor.(black color absorbs light).
Repeat your video with any white object and you will notice the difference..
Now i am using Autostart and it works great with samsung original flip cover (white flipcover).
you can use any white sticker on the black one.

ya correct, just few day back i have asked this issue to developer

But it will work perfact if you use proximity + light both sensor enabled.
Color has no influence, distance between an object and the proximity sensor is what matters. I've just tested this using pieces of paper, cloth, metal and wood in white and black colors. The sensor seems unable to correctly register anything that is less than approximately 1 mm away from the glass (it may report 0 cm or jump to 5 cm). Also it seems it only reports changes of a certain minimal distance between two readings, even if the reported value remains the same as the old one. Anything below the threshold of the 5 cm reading will always result in a reported value of 0 cm, but if the effective distance between reading A and reading B was below a certain threshold, the sensor will not report a new reading of 0 cm (thus an object hovering stable over the sensor will not produce a 2nd post). I'm not sure if the sensor has a state that can be read at any time. From my tests using AutomateIt Pro, it seems only new posts can be used by apps. And if the delta between two readings is to small to make the sensor post a "new" result, then this can be problematic under certain circumstances (like trying to turn the screen off after the flip cover got closed (prox. sensor = 0 for 0 sec) and stays closed (light sensor = 10 for 5 sec) while preventing the screen from going off after an accidental wipe over the prox. sensor e.g. with the hand).
@Dr. Ketan: I've tested Power Switch (again) and I'm quite certain that for the Note + Flip Cover it only works through the light sensor (which is unsatisfying since it then won't work correctly in the dark). Covering the proximity sensor only doesn't make the app reliably react.
Power switch works ok for me with the Samsung flip cover. I have the confirmation set to minimum Abe theactivation delay set to 0 seconds.
It doesn't always work from the lock screen but works fine from the home screen or apps

so is it a hardware issue of software?
might it be fixes in ICS? it's fu***ng annoying! just bought the flip cover(black) yesterday and also bought smart cover app, my note's screen keeps on turn off (when flip closed) then it turns back on (flip still closed)!
Any solution for gingerbread? like proximity calibrator perhaps? (while waiting for final version of ics to come out)
Power switch will work if you use proximity + light sensor both.

It's so sensitive that the moment my finger move over the sensor, the shutdown menu pops up.
Any app that works with the flip cover?
Exactly as title says. Anyone else have the official clear view case from Samsung? Does AOD work when your cover is closed? Would be pretty convenient and for some reason Samsung decided not to include this handy feature...
It's a limitation I think.
AOD require light sensor, proximity sensor and some other sensor to work. The cover render these sensor useless and then may cause problem with AOD, so that's what I think why samsung disable it.

Well the proximity sensors work when talking on the phone with the cover closed... Seems like to me this can be implemented with a minor update.

Are you sure?
I'm not sure about how this kind of case work on new device but I used to have S-view case on my old s4 and it doesn't use proximity sensor to turn display off when calling with cover closed but use motion sensor to detect the movement of the phone to guess whether I'm holding my phone close to my face (and it fail sometimes)
Maybe you can test this by placing your phone on the table when recieving call. Without moving the phone, try cover the proximity sensor and see whether the screen is off.

You are correct sir, it does not use the proximity sensors when the clear cover is on. But even with that, it uses the phone's other sensors to wake and sleep the screen... Why can't this be applied to the AOD? Just a little thing that would be nice to have.

Because AOD use proximity sensor to detect whether your phone is in the pocket and turn itself off to save battery. Motion sensor can't do that. Also for motion sensor to detect your movement it need to be on all the time, thus massive battery drain.
I from Poland and little speak english. But try describe my problem.
When I choose/answer call, screen turn off. Is ok.
But when I end speak, screen no turn on. I must press power.
Then I see screen lock.
I check proximity sensor in androidsensor. Is ok.
I think is problem in software. Turn on needlessly screen lock.
ı had same issue.I solved that with uninstall update of asus dialer ,contacts and calling screen, and now it is working very well.
I use dialer one. Asus dialer I uninstall.
Do you have screen protector on it? Is there any hole at proximity sensor?

This.. I had the same problem, solved it by cutting a piece of my screen protector over proximity sensor
In titanium backup I no see asus dialer.
But shopplay is.
I uninstall update and now ok.
thx ahmt142
I have the same issue, a double tap on unlock button wakes the screen again. Dont make calls that much so no big deal
You can check if prox sensor is bad by opening calculator app and typing ".12345+=" (no quotes) and testing sensor by moving had close and away. Also cheap screen/tempered glass without hole for sensor, causes issues

Hey guys,
I recently bought a 2019 galaxy tab A 8.0" with S-Pen.
It's working amazing, especially with the S-Pen.
But I have a little question, does the tablet have a magnetic sleep sensor to use smart flip cover to put the device in sleep mode?
I bought a cover that was supposed to have it. The cover itself is nice, but it doesn't trigger it the screen on/off at all.
So I'm wondering if the device even has the sensor, since I can't find any option anywhere either.
After some info I just found, this function should work with proximity sensor?
I checked, the tab does have a proximity sensor in the top, but I can't find the option anywhere.
And putting my finger on the proximity sensor doesn't seem to do anything.
Edit: seems like the tablet doesn't have proximity sensor, but only light sensor...
So impossible to get a sleep/wake up cover.
That's lame.
