With the SGT, I have a case for it and have been reading in all the specs that it does have a proximity sensor... but how do you actually get it to work?
I would love if I could open the case and it turned on, and then off. So far I have not read anything about using the proximity sensor in any way on the Tab.
Any help??
Thanks!
I don't think that will happen since apple have just patented that idea (I think)

I was under the impression that the Tab did not have a proximity sensor. All of the Galaxy S devices do, but that's because you put it close to your face when talking on it. The Tab doesn't have a handset speaker on it, so I don't think it would be necessary.
does the galaxy tab actually have proximity sensor , or has any one tried it
Well, for what it is worth, I remember having a metal detector on my TMo G1 that used the proximity sensor, so the white fruit company can't say they had the idea first.

Hello, just one simple question: where's proximity sensor in the A500/A501? I have the Acer flip case but if I close it the screen stays on... Should I enable it somewhere in the settings?
Are you referring to the ambient light sensor? If so, its on the top left bezel, between the volume rocker and the rotation lock. If you look at the black glass there in bright light, you will see a small dark spot, that is the sensor.
As for a setting, the screen will dim based on ambient light levels, not shut off. The setting for it is located by tapping the clock, then the settings button, then the word "auto" next to the brightness slider.
Was this post helpful? If so give thanks
The correct answer is a question... What proximity sensor?
this is driving me nut
the Acer case will always partially cover this one and the dispaly will fluctuate the brightness in random... ;(
pushing A500 firmly into the case solves for a while before happening again - think I need new case...
Based upon this site that contains the tech specs, http://gadgetian.com/10395/acer-iconia-tab-a501-specs-price, the A501 should contain a "proximity sensor to turn it on or off". Please note that if you google for "Acer iconia tab proximity sensor" you will get a number of results, so I doubt that it's just a mistake of one site.
So there's no way to turn the screen off while the tab is properly fitted in its sleeve?
Couldnt the light sensor be used as a proximity sensor? With software I mean.
I have checked my tablet from top to bottom and even made some sensor test to make sure that everything is working and I never saw a listing for a proximity sensor so I'm sure that we don't have one (or a barometer... that was also one of the things that was possible to test ).
@cd85233: Probably yes but I wonder what kind of impact it would have on the battery.
there is no proximity sensor on the A500 nor A501. refered to spec sheet and hardware implementation... unless they changed it since last release.
who told you so ?
Guys, there's an app called tasker. You can use that to tell the tablet to lock up when it receives less than 3 or so % light reading from the light sensor. It works great on the gtab. Still waiting for the case for my iconia to test it out.

still an ambient light sensor, not proximity sensor. As for if it could bbe used as one by software I'm not sure. For the case, look up roocases for the acer iconia on amazon. I have the folio multi-angle black n love it!

This works 100%. Just did it on my Iconia.
Set the trigger to be light between 0 and 5% and the action to be "Display"->System lock.
Let me know if you guys need help but this is easy and works AMAZINGLY. I don't know if more battery use occurs to poll the sensor though. Will report if I see it in the battery usage.

I get it, now you know n its kinda like how one off the wall chinese tablet has a "gravity sensor". Is it an accelerometer? Gyroscope? Our does it merely sense the presence of gravity? Will the device go haywire if used in outer space? Who knows! Lol tech specs can be painfully vague and inaccurate. Especially on a company who can't even figure out to name the source code for their kernel something that doesn't make it look like a help file, THEN place it in the documentation portion of the site, good job Acer! Point being I get the confusion

I recently tried an app called "android sensor box". All sensors seem to work fine except the magnetic sensor. It seems to detect strong magnetic forces somewhere. However, when I use my N1 phone and turn on the sensor, the sensor in N1 does not detect anything. Is that something wrong with Nexus 7 magnetic sensor? Anybody have the same issue?
Is that in the developer section? Oh, and did you check to make sure Magneto isn't hiding in the closet? (There's a pun in there)

I am not developing this app. I just want to check if the sensors in my Nexus 7 function properly.
There is no Magneto close to my room. The odd thing is the sensor in my phone does not pick up any magnetic forces when I compare both devices side by side. I thought about the N7 case may cause such interference but then when I remove the N7 from the case, it still behaves the same. Also, I installed a compass app to both devices. It appears to me that the one in N7 does not function properly, pointing to the wrong direction, even after I did the calibration as suggested by the app.
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.

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'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.

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
I am using my GS4 running armband with my G2, it fits well actually but there is one MAJOR issue. The phone will NOT wakeup when double tapping the screen. It will however turn off when double tapping the status bar. Has anyone else gone running with their G2? If so how has it worked out and what armband are you using?
Be sure the proximity sensor isnt covered, if this is covered it doesnt listen, probably to prevent from turning on in your pocket.

KnockOn is also affected by the orientation of the phone. If it doesn't detect that it is in an appropriate orientation for typical phone use it will ignore the KnockOn feature.

I have tested that, it turns on at all angles and even upside down. I don't think that is very accurate, even if LG advertises that. I am guessing my arm band is too thick.

Just got my international version yesterday and was really bummed to discover the same issue this morning.
It definitely has sonething to do with the proximity/light sensor next to the LED getting thrown off my the plastic of the armband view area.
I experimented by pressing the plastic flat against the phone and it then worked. Obviously not practical to try and do while running, but its a start. I imagine that, while not ideal, cutting a section from the armband window may help
Will post if I find something else
I bought the official flip case. It has a magnet in the front. Unfortunately Moto have used a rather powerful neodinium magnet. So, your phones magnetometer will follow the edge of the case around rather than true north!!!! This doesn't matter for gps navigation, but for on foot travel, and any augmented reality apps that use the compass this case will make the behave oddly.
I don't know what the long term effect on the phones compass will be, but I don't expect it to be good.
In addition, but for me I think it is a small risk, this magnet will be capable of damaging some computer storage mediums and possibly, wiping swipe card data...
I have no idea why they chose to use such an aggressive magnet. I can hang the phone from a metal bar with it, no problem.
Just thought I would share....

Yes sir, you should that. It is ridiculous to make such design mistake on an official case. I was about to buy one but after reading your story I am not sure anymore. Keep us posted.
Btw; you can contact Motorola via their official app Moto Care.
Glad to know, that I am not the only one who is concerned about that magnet. By the way there are two magnets. A weak one to trigger the screen on/off and a strong magnet to keep the case closed.
After removing the strong magnet you will be able to use the compass with the cover flipped to the backside.

Edit: The strong magnet was on the lower third, where the cut is visible.

spoke to moto care. sent them screen shots of the magnetometer all messed up. They said they will get back to me, but no one else has reported issues... *cough* bull**** *cough...
I have noticed today that even when I remove the case, the magnetic sensor is all messed up. It seems after a week of use it has screwed up the sensors calibration (probably correctable)..
evidently, part of the cheap price is a lack of proper beta testing of the phone and accessories....

With GPS Status from Play Store you can force recalibration.

there is a small metal square on the inside of the flip cases backcase. I 'think' this is intended to shield the sensor from the magnet when the case is open. It clearly is TOTALLY inadequate to the task. I'm speculating this is what the metal square is for, as it corresponds in position exactly with one of the magnets in the case door, and this metal square is not present on the normal back case..
Simply lazy design and testing... why does it even need a magnet to stay closed :/ its like closing a book with a magnet lol, they get along fine without them!!!!

Thank you for contacting Motorola.
We regret that there is no possible solution. Compasses operate by magnetic field, and any interference with any compass magnet. There is no way around this.
If you are using a Motorola original case, rest assured that will not hurt your terminal. Imam to close the lid affects the compass but not strong enough to damage the terminal or delete any internal memory power. We apologize for the inconvenience.

As long as the flip shell is folded completely over (so it is flush with the back) my wife's compass works flawlessly. It's actually better than my n4. As I only have one sample to go off of I'm not saying this issue is being over hyped but it isn't always an issue

I've tried it this way. If you fold it completely flat, and line it up to the millemeter, the compass works about 50% well. It generally adjusts to north, but it flicks back and forth between north and where the magnet is on the case. You can also see the gauss meter jumping around a lot.
I suspect the magnetic power of the magnets in the case vary a large amount they wont be very expensive ones after all..
