So I found out the hard way that the Tab 2 10.1 doesn't come with a proximity sensor (not sure how I missed this). Has anyone found an app that turns the screen on/off by opening and closing a case?
My assumption is that this isn't possible without a proximity sensor but thought I'd ask.

Shouldn't be impossible at all.. the device auto senses what the screen light should be I do not know if it uses the camera for this or if there is a second sensor to accomplish this.. but it sounds totally feasible to write a program that senses total darkness to tell the device to sleep Im not so sure how turning it back on would work..this would be am awesome app please post back if you find one

Here there, sorry I don't think it is possible, even smart cover app relys on proximity sensor.
And no, light sensor wouldn't work in dark places or at night.
I believe proximity sensor is only present in cellular models. If so, on your dialpad/keypad, type *#0*# -> sensor -> and place an object near the top of the tablet where the speaker and light/prox sensors are located.
Screen should turn green, and PROXIMITY:0.0 -> PROXIMITY:1.0
Im not much on coding but you would see some light at night from the screen unless the sensor just sucks or the case lets too much light escape i dont see why it wouldnt.

The sensors are only effective if light in shinning directly above it. If light sensors were this sensitive (picking up light from screen), I adobt putting a smart cover on or putting it in your pocket isn't going to work since neither pockets or smart covers are completely light proof as sensors are near the top picking up reddish/faint light.
Cover isn't flat enough to stop screen backlight from traveling accorss the surface of tab and therefore sensors won't be triggered.
Common sense
do you try the Power Switch Pro?
Power Switch Pro works with my Tab 2 7.0 and I would think it would work with the 10.1. There is a lite version on Play that you can try. I liked it well enough to buy it.

I'll get it a shot and see if it works. Are you using the wireless or cellular version?

I'm using the wireless version. It works on my Samsung and also on the wife's rooted Nook tablet. It actually works the best when using the motion sensor and laying it upside down when you want it to turn off. A couple of times it didn't respond as quickly when lying on the back, but it works 100% of the time when laid upside down.

There is also a app at google play called Killswitch Lite.
power switch pro seems to do the job to a certain point. it works good outside, but when you are inside a room or place with a litle less light it starts to pop up that notification window and shut down the screen. maybe be it can be adjusted with the light sensor sensitivity but i found that so disturbing that i disable it.
for me it doesnt do the desired job. if someone has some idea how to make this useful will be thankful.

Like I said earlier
searsh smart cover on google play best one is about 2 $
I use Case Sensor on my Tab 10.1" and it does it's job. It does use the light sensor so during night time or dark areas, it won't activate thinking the case is still covering the light sensor. This app is clever in that when you press the power button, it will override the app for a temporary amount of time. Good enough until someone else can think of a better way to execute or use a combination on different sensors to control the screen
My current Note has the proximity senor issue where it thinks my face is to the phone all the time and therefore gestures don't work and the screen goes black instantly when making a call. This has been outlined in a few threads. Here are two good ones:
This post has actual values for ADC:
http://forums.androidcentral.com/sa...-sensor-issue-during-calls-3.html#post3234634
Another with the same problem:
http://forum.xda-developers.com/showthread.php?t=2520118
I looked at a new note today that Bell is going to let me exchange my current note for. Its value with nothing close to it is about 30.
I would like to know what other peoples ADC values are. Simply enter *#0*# into your dialer, then choose sensors and you will see the ADC value with the proximity sensor. Could you please report that value with nothing close to the screen.
I'm trying to determine what the normal ADC value should be on a new working phone so I can figure out if the new phone (that has an ADC value of 30) is ok or not.
Thanks and hopefully this will help out other people.
Mine seems to stay at 33-35 until about 20cm away from the screen then starts increasing.
I don't have any problem what so ever with the screen turning off/on when calling. Not even once failed.
My values for ADC are 0, constantly 0, if nothing in front of the device. If i approximate my hand it starts increasing, and then the screen turns green and the phone vibrates when the proximity sensor goes from 0 to 1. If i put my finger on top of the sensor it stays at ADC 1003.
Is this how it is supposed to work?
N9005 with MJ7 firmware.
Mine is always below 10 if nothing is in front. Fluctuate between 5 and 9.

My ADC values fluctuate between 30 - 34. @antt00, how come yours so low?
My first note idiled at around 29-30. My second replacement note idles between 0-1. I had proximity problems with my S4 so I check it religiously. While values around 30 would be okay for now, but you may run into problems later. The problems come when you have some dust that gets stuck inside on the sensor and causes a higher adc value. This is what causes the sensor to not work correctly. I have to take apart my S4 every 3 month or so just the clean it and then the number will drop back down to 6. Also keep in mind, the reading goes up a bit in direct sunlight. IMO I would get one that idles around 0, this will give you more headroom for dust.
Thanks for the feedback. I didn't get a chance to read all the posts before I went and got an exchange. For some reason their system let me exchange it even though I past 15 days so I kind of jumped on the chance. The new note at home reads around 20. Not as low as some but better then what I returned. I'll have to see how long it lasts and I'll keep and eye on it. It definitely sounds like its a combination of possibly bad/poor sensors. Dust build up inside which is a design flaw. And maybe poor calibration from samsung as it look like from a post I've see that you can re-calibrate the sensor, though I not sure if that may have some negative effects.
I didn't try and push them to let me cherry pick a phone, they were nice enough to let me check the ADC value and firmware version before the exchange. Hopefully this one works out or I'll have to try and get a better one. I'll see in time as my previous one definitely had the dust issue. It was pretty obvious because I could lower the ADC value if I blew compressed air in the ear piece.
i did notice the proximity sensor screwing around on phone calls, it would delay getting the screen back after distancing from it...
the procedure you gave me shows ADC values contentiously flipping from 9 to/through 13 (sometimes chronologically)
putting your hand over seems to green-out the window showing that proximity is working, nice, however, im having shadow greens, meaning, just leaving it on the table, once a minute it goes green, yet nothing moves over it...strange.
ps, no plastic cover used, dont see a reason to use protection with this quality

Yes but that does not obstruct the sensor. It only reaches below it.
Idling 0 with and without direct artificial light (no tested against sunlight). As my palm gets closer the number progressively increases. The screen turns green after reaching 120
I had no idea that a proper cleaning could fix the sensor. Thanks for the info
iiSo say we all!! From my Note 3 (N9005)
Well now I'm at about ADC 40. In two days the value has doubled. I can't win....
I have this problem with my AT&T N900A and the ADC value is between 82 and 85 at idle. If I wave my hand over the sensor it will go to 1000 but unfortunately its still not responding when I pull the phone from my face after a phone call.
I'm not rooted so I'm not going to manually adjust anything. Is the fix just to get another phone. This is sort of pissing me off. I've had 6 or so Samsung phones and never a problem so frustrating as this one.
And now I'm at ADC 90 and when I activate the sensor (screen goes green and vibrates) it won't stop when I move my hand away. There must be a serious design flaw that allows dust to get onto the sensor. Unfortunately I don't see any way to solve this....I don't know how many times I can return the phone and hope to get one that doesn't allow dust in. I guess the next step is to try and talk to Samsung.....
Has anyone gone as far as to replace the sensor? There is a part out there. Its listed as a 9000/9005 part, not sure if it works with US carrier models. I'm having a hard time finding it in stock anywhere though.
http://rounded.com/samsung-galaxy-note-3-n9005-front-camera-proximity-sensor.html?sl=EN
I have zero desire to send my device to a Samsung service center. I'd have to order a phone to use in the mean time until it came back. I'd rather just swap a new part in.
0/0/0
when i move one hand about 14-16cm above the device (and move it closer to it) the numbers start to increase

I have a strong feeling that its just dust getting in the way. I was at ADC 90, blew air at the ear piece and it dropped to ADC 60. Though I don't know how it looks like inside. I have a feeling some are sealing out the dust completely and some are not.
I do find it odd though that mine started out from factory at ADC 30

I'm not really satisfied with the idea of periodically blowing into the ear piece of the phone with a can of air I don't regularly have otherwise. They need to accommodate the issue with a software fix for the sensor sensitivity if they can't fix the manufacturing process.

Now I'm ADC 99 and my screen doesn't turn on or off properly again. Haven't had a chance to call Samsung yet but this is really annoying. I also don't want return it and get a phone with the new bootloader. Ugh
I'm running latest cm11 nightly (27Jan) on my Samsung Galaxy S4 I9505 international version (jfltexx), but noticed the proximity sensor is broken since quite a few nightlies ago.
When I take a call, the screen goes off, but then it never comes back on again until I press the power button, or after a long delay. Checking with cpu-z, the sensor initially detects 0cm when u touch the proximity sensor, but upon lifting finger, it never gives a higher value (usually limit at 8cm). I can't post to the cm11 development thread to get help on this (maybe coz I've not chalked up enough post counts). Any idea on this will be much appreciated, thks.

maybe it is dirty? from the inside of glass, i had this, posted how to disassemble S4 and how to clean the sensor and glass from the inside. from 43-51 (avarage sensor value) i got 12-16 and the trigger is 46 (going back from close to far).
I had the same symptoms as you, screen black untli i pressed something.

Been using my tegra note for a few days happily enjoying it's brilliance, but yesterday I started noticing the touch screen was not working in certain areas, in particular either all down one edge then all down the other, strangely enough it seemed to change depending on the position I had the device in.
If I had it up in landscape mode the bottom strip was not picking up m my touches at all, especially difficult typing,
Then we I had it in hand Landscape or portrait, the far edge would stop working... Then it came to me, I flapped the cover away so not doubled back and flapped around the back of the device.
Screen had been perfect, so then I tested positioning the magnet strip in the cover in different places along the back of the tegra, and where ever it was positioned the screen would be less sensitive, weird or simply not working.
The reason this had only shown yesterday is because that's when I first fitted and started using the flip cover
Going to return the cover, and let the manufacturers know.

I think this is a software issue, I've seen the same behaviour. Locking and unlocking the tablet seems to bring back the deadzones.
I carry my note 3 (Hyperdrive 7 android 4.3) in a pouch. Something periodically turns my screen to full on, phone gets hit in pouch, and battery burns very fast. I cannot ID the app using the usual battery watching apps. Is there a way to specifically determine what turned the screen on? Thanks!
