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?
Hey there,
I got one of those "smart" cases which send my Nexus 10 to sleep and wake it up once i close/open the front cover.
However i wondered how this really works, is there a sensor within the Nexus 10?
Also , i lately put my Nexus 10 the wrong way round(with the screen still facing me but the lower bottom, where the pogo connector is being up and the camera being down) in the case and closed the front. As expected the Screen didnt shut nor did it wake up when i opened it.
So i guess there is no sensor on that side of the tablet?Is it possible then to harm the hardware inside by the magnet withing the case. I mean when i put it in the wrong way round.
Thanks in advance for your help!

LOL. There is no wrong way! OK. There is. Don't drop it on a hard surface.
There are magnets in your case that trigger the wake up/down of your N10.
the magnetic sensor is right about the left side of the ambient light sensor... try running a fridge magnet there and see the screen go off and on when the magnet is away...
Hey everyone. I've been reading a lot on here and I just want to say that I appreciate all the help,advice, and tips everyone has put out ! I have a small question of my own here today.
Is there a way to turn the screen on of the Nexus 4 without using the power button ? Maybe a gesture that you can do on the screen ? flip the screen over ? I'm open to any idea ! If possible, I would like to hear of something that has been actually tested on a nexus 4 as I don't want to screw up my phone in any way. I'm sure I'm not the only one that is worried about wearing out their phone's power button !
Thanks all !
Sweep 2 wake.
There are at least a couple of kernels that support it. I believe Faux123's kernel does. Check original development.
touch control... an app by bponury... http://forum.xda-developers.com/showthread.php?t=2101488
Use either sweep2wake or volume wake.

AW: [Q] Is there a Power Button alternative ?
Try Auto Screen On. Works really well!

I use intellicover and it works awesome. Uses your proximity sensor and you can just move your hand over it to wake the phone up. Only problem is it is on all the time, so if I'm playing a game and move my hand over the proximity sensor, it shuts the screen off. Really easy to disable though.

TOUCH CONTROL is awesome, all gesture controls. Pick the start and end area of your gesture to turn your screen on or set it to double tap to wake.
To turn display off swipe left to right or right to left across dock area. Nice thing about using gestures over using proximity sensor is in and out of pocket wont wake your display and if your holding your phone with say one hand its pretty tough an awkward to extend your thumb across your screen in order to wave past your sensor, where as gesture can all be done using just one hand and one finger.
touch control is awesome, but consume lot of battery. one day I test the power consumption, turn on 3G data only, non wifi or GPS signal, pull off the plug at 00:00, when I wake up at 7:00, the power remain 81%. I only install two apps, facebook and whatsapp. :crying:
Touch control app on my phone doesn't use hardly any power at all. It isn't in the list of apps under battery and isn't even causing any wakelocks that I can see, and i'm still getting my usual 3-5 hours screen on (depending what i'm doing) and over 20 hours standby.
I seriously recommend this app.
The sweep2wake thing in faux's kernel take two swipes every time to turn my phone on so I use the app.
Hey guys, this is extremely bothering. I have an xqisit folio case that also doubles as a stand. Anyways, when I open the case, the screen lights up, and if I open it just ever so slightly, I notice there's this view mode that displays time and battery, the information that shows through the s view cover.
Anyways, I don't own a s view cover nor do I want one. I also don't want the screen to light up when I open the case because that means the screen's not completely off/phone's not completely resting and uses up more battery.
How the hell can I disable this? I've googled and found nothing and also gone through the settings but found nothing there as well.

well i suppose your folio case uses also the magnetic sensor used by the s-view cover to turn the screen on and off.
as this switch was primary implemented for the s-view cover its the default behaviour to show the s-view screen when you close your cover.
afaik there is no mod to change it right now but i hope this "s-view mode" will be customizable in future with the help of our fantastic community devs! :fingers-crossed:
anyway dont worry about the battery consumption too much as the s-view screen is only displayed for about 5 seconds and then the screen turns completely off.

Thanks a lot! Out of thanks for the moment so can't thank you.
I have S view cover.
When the screen is unlocked and you close the cover, it will show the time. If u open it a little, it will still show time. But if you open it till roughly more than 30 degrees, it will either show the lockscreen(for those with passcode/pin etc.) or homescreen(for those with no lock).
When screen is off and you close the cover, it will not show anything. Open the cover alittle, maybe around 20degrees, it will still not show anything.
Sometimes I have to knock knock twice in a row to turn on the device. It works well turning off, but on half of the times it won't turn on. Gotta do it twice. Anyone else encounter this?

I do not have that issue, but I have read in a few posts that it can be dependent on where you are knocking on the screen.

I think the biggest issue is knock speed.... mine works damn near 100% when I slowed down some, and knock slower like it showes at the end of the G2 commercials....
I think it's partially related to the proximity sensor. There are times when I can't get the knock on to work at all and when I hit the power button the screen shuts right back off.
Usually a few swipes over the sensor makes it work again. Sometimes I'll go in and turn the Knock On gesture off and back on and then it seems to work great for a while too.

This is my exact problem. The phone just decides it doesn't want to wake up with knock-on...but after I press the power button, it only turns on for half a second and it's out again. I never tried swiping over the sensor, but hopefully it works because it's mighty annoying when it does it during a call!
I wonder if there's a fix for this?

this, if you are trying to do it like you did on the nokia n9 or nokia 8800 then it won't work
slow deliberate knocks are the only way
waiting on the g2 to arrive, but on my review unit, knock knock wouldn't respond correctly if i left the phone on the table, but if i picked it up, it would work nothing scientific here just an experience of one person and one prototype
I had the same issue... What fixed it is: 1. I found that the screen protector was hindering it somewhat. 2. Go to settings->display->screen-off effect-> and change it to simple. This REALLY seemed to help. Let us know!

I did notice it does seem to behave better when set to simple for the screen off animation.
My screen protector does have a cutout around the sensors. Keeping the sensor area clean enough to qualify as having OCD does seem to make it work properly the first time, every time. Maybe it's overly sensitive?
Edit: Scratch that. 30 seconds later it's behaving erratically again. Maybe it's not the fact that it's clean, but the swiping over the sensor that temporarily resolves it.
it also seems to work much better when knocking at the top of the screen where the statusbar would be.
So I ended up swapping the phone out over the weekend for a new one and now everything seems to work just fine. Seems to indicate that it's not a software problem, but rather a hardware issue with the proximity sensor.
Guys if your covering the sensors when turing the device screen on it will turn right back of on you. It's a feature LG implemented so the device wouldnt wake up in your pockets. Don't cover the sensors.
Need a little example? Grab your phone and cover the sensors and knock knock knock.You can knock till the cows come home but it will not turn on. Same thing goes for the power button but its a little delayed and will turn the screen on for half a sec and turn right back off. Practice not to do this because your phone isn't broken. There is actually a thread on this deep in the forums somewhere but its been forgotten now.

This is true however there are indications of problems with the proximity sensor as well. Some of the devices are behaving as if tree sensor is covered even when it's not.

Thanks for this.. Very insightful.. I tried it immediately LOL
I had the same issue. I have no case or screen protector on, and was not covering the sensor when trying to wake the phone. For some reason though, knocking wouldn't wake the phone, and pressing the power button would only turn the screen on for a few seconds. I want even given enough time to get past the unlock screen. I went into the store and they are sending me a replacement that should come in later this week. It doesn't happen all the time. It is much more noticeable after receiving a call though.

Definitely is dependent on the proximity sensor. If i just have my thumb on the edge of the phone by the sensor it will display this problem. Even with my finger a half to one inch above it will do this. I will be paying close attention to the proximity sensor from now on when it doesn't work. Still have a few days to return and thought i had an issue but maybe not.

sometimes its also greasy fingers, at least in my case, rarely though
As long as you tap twice the same place it's working fine. If distance between first and second tap is greater than 1 - 1.5 cm it won't work.
Got the same problem on my d802...when i left the phone on my table for 2-3min it wont wake up on first knock knock even power key wake it up for 1sec after auto turn off again....even with no screen protector....i noticed that sometimes there is a delay about 5-10sec after knock knock and screen turns on....other thing i noticed when i knock on immediently after turning off it works 100%....BUT i also noticed when i knock on after a while it turns on and i can unlock got vibration and sound of the unlock but i cant see anything. Screen looks like its off but when i look closely i can hardly see widgets and when i set effect to tv out i can see the effect by pressing the power button...when i press the power button again screen turns on like normal...i noticed sometimes on a rerboot the lg bootlogo disapears the led is working an showing all colors but the boot animation is gone like the screen is off at the bootup...dont know why after the bootup the pin lock screen is showing up normal....sorry for my english^^
