I saw a cover for the nexus 7 that said it turns the screen off and on with the closing and opening of the screen. I assume it's done with the light sensor. Is there any way to dk it with the gt?

those use the proximity sensor, and we don't have one so unfortunately no there is no way to set that up.
Its not the proximity sensor, its some sort of magnetic sensor. It does it if you have a small magnet in the right place on the case. As we do not have such a sensor on the tab, we cannot do the same thing.
In theory, you could write an app that turns off screen depending on what the light sensor senses

Yes we do, theres 2 other things at the top of your tab aside from camera and phone speaker. They are the light and proximity sensorsl

maybe on your 3100 but I installed this app https://play.google.com/store/apps/...51bGwsMSwxLDMsImNvbS5vbWQuYXV0b3NjcmVlbm9uIl0. that uses the proximity sensor to wake the screen and it said there wasn't one on my 3113. All I have is the camera and a light sensor.

ok, cool, auto screen on was just the first I had found and it worked on the device I tested it on so I never looked for any others. still no use on my 3113, it says no proximity sensor.

This works, however if you are using screen timeout, its not saving you much since it just turns the screen off, it does not put the device to sleep. It does function as an auto on / off for the screen. I found it very quirky , sometimes it works when I close the cover, sometimes it does not. Unfortunately there is no sensor calibration. I want to test it to see if it actually uses extra battery in order to keep the sensor alive. Also, its a bit flaky if you use some of the advanced features like turning on and off airplane mode.
Thanks. I didn't know about the magnet.

No need to write such an app. There are several on the play store that do exactly that.
However I've tried them all and I can' get any to work properly using CM10. Others may have better luck.
Use smartcover from android market. It works very well.

I noticed a weird light being emitted from proximity sensor when I entered the stock Samsung messaging app. It looks like it could be an infrared light coming from the sensor, but it's faintly visible to the naked eye. I thought I would take a video of it to show what I'm talking about. It's more apparent in the video than what you actually see. You can see it yourself in a dark room.
Has this been addressed? Does anybody know why this is happening?
isnt it looking to see if you move the phone to your ear in the messaging app so it can do the call feature?
I noticed this on mine last night. It's not like that right now though
I have the Motorola Atrix and when I use the proximity sensor, it does the same thing, glows a very very dim red, only visible in a dark room. Guessing that's how that sensor works in a generic way.

I seem to have found a weird problem with my Nexus 7. I can't wake it up in the dark. If i turn on the lights in the room, the nexus will wake up when i hit push the power button. I can recreate the problem in a lighted room but putting my covering up the camera and light senor. If i turn off the "auto-brightness" feature, It works like normal.
Anyone else having a problem using the Nexus 7 in the dark?

I ran into the exact same problem. I wonder if it is just our tablet. Since I was not sure if this is a hardware issue or a software I started a RMA.
was just about to start a new thread asking about this issue...
well, at least it's good to know that I'm not the only one experiencing this defect.
I wonder if this is a hardware or software issue.
I cover up the light sensor and it wakes up like normal and very dim. Remove my hand and it brightens as I would expect.
You may want to check out an app called "Display Brightness" by Big Rubber Pepper. It will also save you battery by allowing you to control your brightness from 1 to 100% with the swipe of your finger with an invisible slider at the very edge of your screen that can be customized for any location.
yeah this bug is annoying me. Hope they fix it soon.

Powers on fine here with auto-brightness in complete darkness. Return it to stock to see if it clears up.
I'm getting this too. Also if I manually do the brightness slider all the way to the bottom the screen goes off.. I thought it was bricked at first then turned the light on and hey presto! I'm running a stock rom but its rooted, deodexed and also running the tablet ui patch (dpi set at default 213).

Just an update... I got the replacement and that Nexus 7 tablet doesn't have the auto-brightness issue so I guess it was a hardware problem and I am glad I did the RMA or else it would have kept bugging me
Also finding the auto brightness to not work right, one of the applications I downloaded showed the sensor bouncing around a lot. I picked up Lux brightness and it seems to do a better job of moderating automatic brightness with the ability to set custom levels based on the ambient light.

Hello everyone.
The proximity sensor just always turned on. I don't know what program using it. I wish there is a application to view exactly what program using a sensor.
Thank you.

Q: Is this proximity sensor related to 'Smart Rotation' and 'Smart Stay'?
I have found threads and info about how it works on the Note 2, about magnets in the stylus but how does it know when your finger is hovering over the S4 screen?
Anyone know?
I have the same question.

I read somewhere that it was indeed the sensor at the top, mixed with the old technology too.
The apps I know it works with are stock email, stock texts and flipboard. Not sure what else. It doesn't even seem to work on lockscreen...

Samsung is using a super sensitive capacitative touchscreen that can sense your finger even when its a short distance from the screen, essentially. its the same reason that there's an option so that you can use it with gloves on
Sent from my Nexus 7 using Tapatalk 4 Beta
I'm no engineer, but this is my basic understanding gleaned from reading wikipedia and other sources. Capacitive touchscreens work by sensing changes in an electrostatic field. Your finger is an electrical conductor, which distorts the field. In normal phones the field is calibrated to extend just past the surface of the touchscreen. The S4's electrostatic field is simply overcalibrated to sense your finger from a distance, and it's also why it works with gloves on.

nothing to do with the capacitive screen or proximity sensor. if the screen was THAT sensitive it'll be firing off to even the slightest atmospheric disturbance. actual workings are related to the 2 IR sensors flanking the speaker grill which individually log IR intensities emitted by ur finger in front of the screen. an algorithm then compares these values and works out where ur finger is pointing.
AFAIK it works with help of IR Sensor and/with Proximity Sensor
If screen sensitivity does this job then ...Nokia Lumia 920 to 520 all devices all should have this feature cuz all these devices have Super Sensitive screens

The air is much more inert than your finger. The proximity/IR sensors just blast IR beams away from the phone for things like Air Gestures and have nothing to do with Air View. They certainly don't shoot beams across the surface of the screen to detect your finger. The finger hovering simply uses a more sensitive capacitive touchscreen, as Sony explains here:

This happened with me also.
The air view works in stock messaging app , gallery , flipboard and even when you dial a number if you have speed dial feeded.
For this you need to hold air view option in notification bar for about 2 seconds then a set of options will open. There you can switch on air view for messaging, gallery etc etc.

It will be the electromagnetic field that the screen is detecting from your skin/finger. The same way that on other screens, they don't work with gloves unless you have the special gloves that have conductive fingertips on them.
Nothing to do with the sensors on the top of the phone cos if you cover them up, air view still works! Plus the sensors aim out the top and at 90 degrees to the phone face, how would they sense something almost touching the screen on the bottom?

Hi guys, I just got a brand new S4 from Rogers and while playing around with the phone I noticed some of the features weren't working properly. One of them was the palm gestures settings. I tried some many times to get the Screen shot and Play/Pause features to work but it failed. And another problem that I encountered was the gyroscope sensor. As you can see in the screenshot, the ball doesn't move at all even when the phone is standing up. So do I have a defective S4?

That screen is supposed to "calibrate" the gyroscope so it make sense that it doesn't move. You are essentially teaching it where perfectly centered is. In order to do that, you have to lay it on a surface that is perfectly centered. If you lay it on a surface that is not perfectly centered and press it, it will be off. I haven't messed with mine yet, but it seems that is the way it would be.
