Proximity sensor Strange behaviour - not working if u get very close.

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?

[Q] Phone doesnt know that my keyboard is slided out

I have my Desire Z for about 5 months, and now when i want to slide out my keyboard, the screen sometimes stays in portrait mode and pressing the keys doesnt work. when i slowly slide out the keyboard and have it out halfway, the screen flips, but when i slide it further, the screen goes portrait again. I am using a pouch with a magnet, which sometimes confuses my device, thinking the keyboard is slid out while it isnt. but my problem happens without the magnet intefering. Could this have anything to do with it?

I don't know how to fix your issue, but never a good idea to have electronics near a magnet
Sent from my HTC Vision using xda premium

The slider itself uses a magnet to figure out wether the keyboard is slid (or slided) out or not. I'm not sure but i think it is pretty common (i know the htc touch dual also uses a magnet). Anyway, i've tried to keep the back side of the phone away from the magnet of the pouch and so far everything is working fine again. So i guess the sensor was just confused

Have to remember polorization homie. Put a magnet by itself on a tv and see what happense even though there are magnets within tv.
But if its a case with a magnet designed to hold electronics there is nothing to worry about

I had the same issue, i had a loose ribbon on my keyboard

i bought myself a capdase leather flip-case which has a magnet right under the camera.... that magnet is to blame .... but the weird part is the case never interfered when i was on froyo ... but suddenly stopped working(started messing up with the keyboard) after updating to gingerbread.... sadly i found no fix to this ,,, so its $30 down the drain....

Q> how to make your own smart case

I just bought a case off amazon and realized that it doesn't have the auto screen off effects of smart cases. Does any know how to make it so the cover that lay over the screen turn on/off the screen when the case is closed ? I did try running the magnet along the edge of the screen but that doesn't seem to turn off the screen.

Try a stronger magnet.

[Q] Alternative ways to turn screen on/off

Hi all,
I'm wondering if there's any alternative ways to put the Nexus 7 (or any Android device I guess) to sleep/wake it up. I'm thinking something along the lines of an app that forces the touch screen to stay active but turns the display off so you can use touch input to activate wake/sleep.
Might be a bit of a stupid question. The reason I ask is because my N7 is mounted in my car and the power button isn't easily accessible.
Cheers for any tips..

Not sure if this helps but I have a case that I bought for my N7 and when I open it and close it the screen turns on and off.

Thanks for that but nah, it's mounted in my car dash so a case won't fit..
But that give me an idea.. does sliding a magnet across a specific point on the screen turn it on/off? That's the idea with the smart cases right?

Yes,
The magnet is somewhere to the bottom left of the device (i would say to about a quarter from bottom up and on the black contour) . If you can add an sliding magnet (make sure is weak) then you can lock/unlock screen.

Nfc tags dude i wonder if they would work

I know some kernels can enable touch wake. I imagine it can incorporated soon. On my Galaxy Nexus, there's an app I downloaded that allowed a specific screen swipe to wake the screen.

That would be awesome. Do you remember the name of the app?

Gesture Control?

Hey man. I used to have an awesome app on my very first Android tab years ago. It would turn the screen completely black (via home screen or notification icon) without actually putting it to sleep. Because it wasn't really asleep, a double tab would turn the screen back on. I CANNOT FIND IT FOR THE LIFE OF ME! Anyway, after reading your question, I searched for an hour, because I could use something like this for my setup in my car.
So, I found something that turns the screen both on and off, and actually works on my N7. Search for Proximity Screen Off. I installed the free lite version, and it works. I found out the screen won't turn on though, unless you disable your lock screen. Play with the settings to your liking.
Oh, and since we don't have prox sensors, you can use your ambient light sensor. Good luck, lmk if it works for ya.

It's called PGM Nexus. I almost don't want to give up my Galaxy Nexus (but I sadly still plan to) just because of this one app alone...it is so godawful nice to be able to swipe, or simply double tap the screen to fire up the screen. Unfortunately this app apparently requires some deep voodoo to work as its kernel related, and applies strictly to the Galaxy Nexus. I know a bunch of people have already started bugging the developer to make a version for the Nexus 7, I'd suggest piling on. :fingers-crossed:
It's apps like these that make you realize how superior the Nexus devices are at getting really good customized software over other devices.
I do wish there were some other options for the Nexus 7, like using the front camera as a proximity sensor of sorts to detect a handwave, or simply shaking the tablet.

Thanks for that! Appreciate it. I'll give it a try when I get home after work and report back.

Could you please post the settings you are using? Specifically the light sensor settings. I am having trouble getting this to work properly. Thanks!

Hello. I'm not sure if it helps you, but for turning off screen I use Nova Launcer (alternatively you could use Apex Launcher - as far as I remember, it has gestures in its free version) with Screen Off app by Katecca. I've set Nova Launcher to react to swiping up screen by executing Screen Off app. So I have to turn on screen by pressing button, but to turn off I just swipe up screen.
Best regards,
Artur

Screen Wake Speed With Smart Cover - Increase Wake Speed??

Hi,
I have the MOKO slim case, just wondering if im able to increase the speed in which the screen wakes when I open the case?
Been looking and there are some mods to edit the proximity sensor but I believe its another sensor id need to modify.
Any ideas chaps?
I want to have less of a wait turning the screen on when I pull back the cover
Thanks
N

I don't know about you but my tab is awake the second I lift up the cover an inch away... By the time it is fully open it is well awake

mine kinda takes a little while too, but i dont really mind it. I have the moko too and by the time i get the flap behind the tablet its on

Sometimes it will lag if you closed it on a different orientation then your opening it. (Portrait/landscape)
