Android :: How To Turn On / Off Screen Using Proximity Sensor?

Sep 21, 2009

I have an application that needs to turn on/off the screen using the proximity sensor like what most dialer applications do when a user is making a phone call. I cannot seem to find a way to turn on/off the screen at will.

Sony Ericsson Xperia X10 :: Proximity Sensor - Screen Does Not Turn Off Instantly

Apr 9, 2010

When I'm in a call and put the phone to my ear the screen does not turn off instantly. Only after the screen timeout period has reached does the screen goes off. Is this normal?

HTC Desire :: Use Proximity Sensor To Disable Screen While In Pocket

Jun 8, 2010

I've experienced the problem that when the desire is in my pocket and I receive a notification, the screen gets accidentally unlocked and the phone starts doing things that I don't want it to do. I know I can add an unlock pattern so that it won't unlock as easily but this is at the expense of me having to enter it even in situations I would not have needed it. So I thought that maybe we could use the proximity sensor to tell the phone to never unlock the screen if an object is close to the phone. Quickly looking at the android docs, it seems that the support for this is in the SDK, but I was wondering if anyone had created an application that does this. If time permits, I might even have a look at doing it myself, but as I'm very new to Android development, it will take me quite a long time to get to a usable state, hence my question about an existing app that does this.

HTC Droid Eris :: Screen Replacement Seems To Have Broken Proximity Sensor

Oct 6, 2010

I bought and installed a new screen (digitizer) in my Eris. The install went very well but now the proximity sensor doesn't seem to work properly. Most times when I place a call the screens goes blank and won't respond to any button inputs, Once the other party hangs up I get the screen back. But even this is erratic at times, not often, with the screen staying on all the time.

I installed Screebl Lite to force the screen on all the time and it works most of the time but seems to have a hard time figuring out the proximity sensor too.

Is there something I could have done to screw up the sensor when I took the phone apart? Everything else is working fine.

Android :: No Light Sensor / Proximity Sensor Detected On Hero?

Feb 8, 2010

I have a HTC Hero here, and when I tried to get the list of available sensors on the device by calling ((SensorManager) getSystemService (Context.SENSOR_SERVICE)) .getSensorList(Sensor.TYPE_ALL); I get only the following sensors: D/SensorManager( 6302): found sensor: BMA150 3-axis Accelerometer, handle=0 D/SensorManager( 6302): found sensor: AK8973 3-axis Magnetic field sensor, handle=1 D/SensorManager( 6302): found sensor: AK8973 Orientation sensor, handle=2 D/SensorManager( 6302): found sensor: AK8973 Temperature sensor, handle=3 According to the specs, there should be a light and a proximity sensor on the Hero, and I've seen it in action (the automatic screen brightness adjustment) - so at least the ambient light sensor is definitely there. My question is then, why doesn't the getSensorList return for me the light and the proximity sensors?

HTC Desire HD :: Still Having Error With Proximity Sensor

Anyone still having problems with the black screen? Have downloaded and installed the ota update and if anything the problem is worse! Seems ok on incoming calls but if I make an outgoing call the screen goes blank and the only way to reactivate is to hit the power key. This is starting to sound like faulty hardware to me. I read that the ota update was supposed to sort this! Any advise would be appreciated as other than this really annoying problem the phone is great!

HTC Desire :: Little Annoyance With Proximity Sensor

Jul 4, 2010

First of all, I love my Desire, but there's something bothering me that's been costing me some money and trouble: Whenever I accidentaly call someone, I press the back button thinking it hangs up the call. But then I realise it's still calling! So I try to bring up the notification bar, though whenever I try to place my finger near the top of the phone, it automatically turns of the screen. After 20 seconds of trying, I've already lost money and afterwards people call back or message me why I've been calling them. Anyone else had this problem yet?

HTC Desire :: Proximity Sensor During Call

Somehow I keep managing to hang up on calls/call other people during calls.

HTC Legend :: Proximity Sensor Not Operating

Aug 10, 2010

Is there any app, flag or something similar that can be used to bypass the proximity sensor in the HTC Legend? I mean something that makes the screen stay on all the time during a call, neglecting the proximity sensor, as if it is in the speaker mode (but without the speaker on, I don't like people listening my conversations.My problem is the proximity sensor not working. I purchased an unlocked Legend a month ago in the Manchester (UK) airport free shop. I live in Brazil and travel to USA frequently.The phone is under warranty, but for me is too far to send it to Europe for fixing (no maintenance for Legend in Brazil and even in USA, if I knew it I would never buy this thing.)When in a call, the screen and keys go off and there is no way to bring them back.The sensor seems to "think" that the phone is near my head all the time immediately after a call is made or received. Only way to bring the screen and keys back is soft reset even after the end of the call.I already tried all the typical solutions and I don't use any kind of cover over the device, and by comparison with one that works I am sure that there is a problem with the sensor. I just don't want to stay more than a month without the phone and spend nearly the same that I spent in the phone in transportation to send it for fixing, so if there is something just to bypass the sensor it will be much better for me.

Motorola Droid :: Is There A Way A ROM Could Disable Proximity Sensor

Is there a way that a ROM could disable the proximity sensor during a call? I have a huge problem where I constantly hang up on people (usually my girlfriend) and that doesn't go very well . If its possible for the end buttonor volume button to wake the screen instead of the proximity, that would save me a lot of hassle. Is this doable, either standalone or through a rom setting?

Motorola Droid :: Proximity Sensor Error

Mar 20, 2010

I have been having this issue for quite some time, but just figures it was a bug in one of the BB roms I was using. Well, since then I have been through about 10 different versions of bugless beast, droid mod, and several others. My issue seems to be that when I make a phone call and put the phone next to my head, although the screen turns off, the touch is still activated.I will be in a call and I will feel the phone vibrate against my head. I usually hit the pound of star key on the phone, and as soon as buttons are pressed in a call, it seems to mute my voice to the person on the other side of the call. I have to remove the phone from my face, wait for the sensor to realize i moved my face, and have to press the backspace button till all the random characters are deleted at which point the person on the other side can hear me again. This happens to me on about 80% of my calls, and is by far the most frustrating issue I have had. Do you think I should re-install stock and bring it in? btw, I posted this in root sub-forum cause I am rooted, and wasn't sure if it was just a rom issue.

HTC Droid Eris :: How To Disable Proximity Sensor?

Apr 23, 2010

Is there any way to disable it? I put a body skin on it and its barely off center off but its enough to cover the sensor so when i'm in a call its constantly black and i can't do anything . I would just take the skin off and put it back on but i was stupid enough to put it over my invisible shield and im to paranoid to put any more water on my phone and wait another 24 hours. So is there anyway to disable it or do anything?

My sensor quit working over the last few days and I cannot find any settings that will reset it. Ive tried many reboots to include pulling the battery for about 15 minutes. The only thing out of the usual the phone has been subjected to recently is 10 25 degree weather for a little over an hour while I tried to let its gps find itself.(Eris users Buy a REAL gps and Ill save the rant)Oh, and none of the only three additional apps have been installed in the last few weeks.

HTC Droid Eris :: Otterbox Case Disables Proximity Sensor

Mar 14, 2010

I got an Otterbox (IMPACT) case for my wife's Droid Eris. I have verified that when the case is on, the proximity sensor does not operate at all. Take case off, works fine. Case is on correctly (there's not a whole lot of ways to have it on wrong). Pressing it harder onto my head (which one shouldn't have to do) or holding it farther away don't help, either. Does the other Otterbox case do this?

Samsung I7500 :: Proximity Sensor Not Work Always While Making Calls

Dec 25, 2009

I have not seen this mentioned but I have trouble with it every day. When I make a call the proximity sensor does not always work. During the call my cheek will pull up the keypad and then start dialing. Sometimes this will happen even if I remember to hit the sleep/wake button as I start the call (to turn off the screen). Very embarrassing to explain to the other party why your phone is touch-toning over their conversation. Does this happen to everyone or just me? It did it with the I4 and now the K4 firmware.

Motorola Droid :: Screen Timeout / Sensor?

Nov 8, 2009

I've read through the deluge of threads that have sprung up since Friday's Droid release. However, I have only seen this issue listed within longer conversations about frustrations. I wouldn't call this a frustration as much as I would a quirkiness of the Moto Droid that I'm hoping some similarly-annoyed person out there has developed an app to overcome this.

The issue is with the screen lock and the auto-dimming on the phone. The first issue with the lock screen is not a device-specific issue as far as I can tell, but it is insanely annoying not to have a lock timeout setting within the OS. I should not have to unlock my phone every single time the screen dims from the timeout setting. Every other phone I've ever owned that has a screen lock does not have this limitation and, if someone were to mention that the iPhone has the same issue, I would point out that they suck.

As for the other issue, and the far worse one, how in the world is the proximity sensor when on a call so damn finicky!? I have read this complaint multiple times on various forums, but no concise list of solutions. The screen goes black when you have the phone to your ear, but when you move it away from your ear, the screen should *consistently* re-light so the user can have access to the keypad, etc.. This is not working at all as I would expect. I did find an app in the marketplace that allows you to set the screen timeouts by application, but if I set it to not timeout on the phone app, the screen will stay lit when I have the phone to my ear, which would defeat the whole purpose.

This seems like a huge bug to have missed in all the testing that occurred before releasing the phone, especially for such a basic feature. I expect customers to go nuts on Verizon for this one (my fiance is far from a technical user and has the Droid and has yelled at me to "fix it" referring to this problem..

Sprint HTC Hero :: Light Sensor And Screen Intensity Linearity

Dec 30, 2009

I've noticed that when viewing the screen in a darkened room that the screen is actually too dark. Yet in a normal setting that the screen is correctly lit. I've tried increasing the intensity to maximum with the sensor enabled and it's still to dark in the darkened room. Now, I've disabled the sensor entirely and the screen just runs wide open all the time - day or night.

Has anyone else felt that it was too dark in the darkened setting? I'm wondering if there is a setting (probably not yet written for the phone/OS) to vary how linear the light sensor is at darker levels? Maybe a 'minimum darkness' adjustment?
