Still tested different NAND-Android Roms on my HD2 but got still a problem. If i make a phone call and the screen turns black while calling i press the endkey to end the phone call. But instead of turning on the device, the screen stays black and i need to pull the battery and restart the phone.
If i make a phone call and use the free speaking funktion, while the screen don't turn off, i got no problem when ending the phone call.
I don't know what the problem could be, but it seems, that the thing has to do with the sensor who turns the screen on and off. But i don't know if this is the problem and/or know how to fix this problem. Like i said, i tested different Android Roms formated the SD-Card, deleted cache and all the stuff, but nothing fixed this problem. :-(
28 Views and no one with this problem? :-(
There are 2 other threads discussing this issue already. Here is one.

Issue lies with the light/proximity sensor. Could be defective hardware. Could be incorrect sensor drivers. Could be dirty sensors. I have yet to take mine apart to check for dirt on sensors. Blowing into the led/earpiece opening seemed to help. I notice if it doesn't come back on I can hold a very bright light (ex: cigarette lighter) about an inch away and the screen comes on as long as the lighter is lit. Sometimes it stays on.
thanks for your answer. seems to be more things to test and maybe solve this problem. Thanks!
THANK YOU Agoattamer!
Your link helped me to solve the problem! I just cutted a little piece of my screen protector, where the proximity sensor is, and got no more freezes after the phone calls! The screen protector still got two holes for the light and proximity sensor, but this seemed not to be big enough. Anyway, thank you a lot for your post!

I also tried a a lot of different NAND ROM and I had also this problem and I can't use Android efficiently. Now I am using hyperdroid ROM ( first GBX now CM). With this ROM and sanity app (from market, with correct settings you can find with trying) I almost solve this problem. ( probability of 95 % I don't get this error)
hey guys! i found the solution goin through the market!
download an app called "Sanity" theres a free version in the regular android market.
go to the settings > general > check "Reverse Proximity" (This will give you some warning about not using it if you DONT have a buggy proximity sensor). Check it anyways. Then go back to preferences then click "Proximity" scroll down and uncheck Turn off screen and leave leave the Turn on screen checked. this will force your phone to stay on during calls so that it never has to go through the proximity phase of calls this no more black screens. Hope this was helpful ^_^

Does any other one tried this solution ???
Hi guys just wondering if you noticed this strange behaviour.
I noticed a quite frustrating delay after a call when i take the phone away from my ear, it takes 2-3 sec for the screen to turn back on.
Has anybody experienced the same?
Do you know if there is a solution for this?
Sent from my GT-I9100 using XDA App
yes, think its normal. looks like the same delay when pushing power button for screen on.

Thank you.
That seems strange as it is something really basic that you expect to work in a phone of this price range. Moreover it's something you come across quite often.
Do you know if the latest firmware improves this?

You can just turn off the sensor in the call app, if you want your screen to be available just after a call.. I don't see the problem.. but my delay is also just around a second or so.

But if I do that i will drain battery unnecessarily. I don't know you guys but I find it really annoying having to wait 2sec after a call for the screen to wake up. I want to be able to hang up immediately i think I'm not asking something ridiculous.

you can also set the power button to terminate the call and you will not have to wait for the screen to turn on...
Reading the data from an analogue sensor (such as the proximity one) is always tricky... You need time to level out the values coming back from it, then determine that, over a period of time, the distance is suitable to enable the screen.
Only then can it be turned on etc

How do you go about doing this? Can it be changed in the setting sor does it require a separate App?

Pls go to settings then call then calls answering ending and tick power key ends calls
Yes i find this very annoying too!
Especially when on a call center, press 2 (wait for screen) then press 4 (wait for screen) you get the idea
this is actually the only problem i have with the SGS2 since ke7

sgs 1 managed it fine though?....or am i missing something
Yeh my i8000 had no delay with the proximity censor.
But the screen delay seems to be everywhere. Turning on from sleep, time to adjust to ambient light and obviously the proximity sensor after pulling it away from your face.
Its not a major drama for me but I agree that it would be good to not have the delay.
I just noticed that when I use Skype the sensor works really well, meaning there is almost no lag.
I'm confused..
Sent from my GT-I9100 using XDA App
Yes! Very annoying.
Yep! I was commenting on this the other day. To be honest, I make and receive very few calls from my phone but when i do, I feel the rage rising inside me everytime because of the sensor delay.
It's the small things that annoy you the most.
As mentioned, you can opt to have the power button hang up the phone. It also does not turn the screen off, so you can continue working on the phone.
This is actually under accessibility settings, not call settings.
Menu -> Settings -> Accessibility -> Cancel the prompt -> Tick 'The power key ends calls'.
I also find the lag on waking up very annoying. Even once the screen has woken up, it takes a second for the touch input to be recognised so the pattern unlock only registers my last two or three inputs depending on how quickly I start swiping. I have to enter the pattern again. Very annoying.

I also have this problem, although I'd estimate it only takes about 1-1.5 seconds for the screen to come on.
I do however not think that this is a sensor problem, but rather a software problem.
Type *#0*# in the dialer, and press Sensor.
The phone will now vibrate once you trigger the proximity sensor. And it seems to be very fast and responsive here.
i have the problem using Skype...when i start a call it turns automatically the screen off ! i need then to push on home button to get out of skype...very ennoying...
last time i made an order online, my bank sent me a code by phone and following the instruction, the voice asked me to push the number i hear...i simply could not !! the screen was completely off ! and i could not succefully purchase online, my order was cancelled !.....due to this problem of screen..i think it is seriously ennoying and must be fixed in an update firm or something .
Agreed, this is a very annoying and unnecessary delay. Especially coming from an iPhone, where the screen turns on instantaneously when removed from the ear.
Hoping for a fix.
im ready to pay to get this fixed
Hi all,
I'm wondering if there's any alternative ways to put the Nexus 7 (or any Android device I guess) to sleep/wake it up. I'm thinking something along the lines of an app that forces the touch screen to stay active but turns the display off so you can use touch input to activate wake/sleep.
Might be a bit of a stupid question. The reason I ask is because my N7 is mounted in my car and the power button isn't easily accessible.
Cheers for any tips..

Thanks for that but nah, it's mounted in my car dash so a case won't fit..
But that give me an idea.. does sliding a magnet across a specific point on the screen turn it on/off? That's the idea with the smart cases right?

Yes,
The magnet is somewhere to the bottom left of the device (i would say to about a quarter from bottom up and on the black contour) . If you can add an sliding magnet (make sure is weak) then you can lock/unlock screen.

I know some kernels can enable touch wake. I imagine it can incorporated soon. On my Galaxy Nexus, there's an app I downloaded that allowed a specific screen swipe to wake the screen.

Hey man. I used to have an awesome app on my very first Android tab years ago. It would turn the screen completely black (via home screen or notification icon) without actually putting it to sleep. Because it wasn't really asleep, a double tab would turn the screen back on. I CANNOT FIND IT FOR THE LIFE OF ME! Anyway, after reading your question, I searched for an hour, because I could use something like this for my setup in my car.
So, I found something that turns the screen both on and off, and actually works on my N7. Search for Proximity Screen Off. I installed the free lite version, and it works. I found out the screen won't turn on though, unless you disable your lock screen. Play with the settings to your liking.
Oh, and since we don't have prox sensors, you can use your ambient light sensor. Good luck, lmk if it works for ya.

It's called PGM Nexus. I almost don't want to give up my Galaxy Nexus (but I sadly still plan to) just because of this one app alone...it is so godawful nice to be able to swipe, or simply double tap the screen to fire up the screen. Unfortunately this app apparently requires some deep voodoo to work as its kernel related, and applies strictly to the Galaxy Nexus. I know a bunch of people have already started bugging the developer to make a version for the Nexus 7, I'd suggest piling on. :fingers-crossed:
It's apps like these that make you realize how superior the Nexus devices are at getting really good customized software over other devices.
I do wish there were some other options for the Nexus 7, like using the front camera as a proximity sensor of sorts to detect a handwave, or simply shaking the tablet.

Hello. I'm not sure if it helps you, but for turning off screen I use Nova Launcer (alternatively you could use Apex Launcher - as far as I remember, it has gestures in its free version) with Screen Off app by Katecca. I've set Nova Launcher to react to swiping up screen by executing Screen Off app. So I have to turn on screen by pressing button, but to turn off I just swipe up screen.
Best regards,
Artur

Hey guys, here's my question.
My wife and I both have the s4. I'm on mf9 rooted, she's on stock unrooted mdl. My phone has always screen waked when I'm on a phone call and pull it away from my face during the call. My wife's does not. I have to manually wake it up once by pressing power. Then anytime after that during the same phone call it will auto wake like I want it to when I pull it away. After I hang up it starts the whole process all over again.
Any suggestions? It looks like all the settings are the same on both phones.
Do you have the "Turn off screen during calls" option checked? To get there, open the Phone app, go into the Keypad tab, click the menu button, and check to see if that option is checked. With it checked, the screen should turn on when you pull your face away from the phone during a phone call.
A screen protector can effect this if it is covering a sensor up above. But this feature can be turned on and off go into the Motion and Gestures under settings and make sure its on.

You might have a faulty proximity sensor on that phone. I had the same problem and it had to be sent to Samsung to be replaced/fixed.

If the option is not turned on, then when he places the phone against his face. The screen would stay on. Right now his problem is the screen is turning off when it's placed on his ear, but will not turn back on when it's taken away unless he pushes the power to turn it back on. I had the same exact thing and it was a faulty proximity sensor that had to be replaced.
I have a crack in my screen which seems to make the phone's sensor think it's constantly pressed against my ear, thus not allowing me to use the keypad during calls, switch apps during calls, and on incoming calls, not even hang up.
I was wondering if anyone knew of any way to disable the automatic screen shutoff so I can get around this. I am using CyanogenMod 10.2 on a rooted Sprint galaxy s4, but have had the same problem with the derrick Samsung os.
Thank you, and if I'm posting this in the wrong place, apologies and please let me know where it belongs!

The screen off during calls is controlled by 1 of the top sensors, not by screen touch...Maybe there is damage to or on the surface area above the sensor...

I know you're on CM but here's how it's done in stock, you can toggle the "Turn off screen during calls" when you bring up the dial pad and hit menu then call settings.
Unselecting that item keeps the screen on as it won't use the proximity settings (like when you put it to your ear) to turn off the screen...which is essentially what you've already described that you think is occurring with the crack in your screen...
hope that helps.

Never noticed that, thanks! I wasn't able to find something similar in my OS. I love CM, but I might have to switch back to stock for this.
Btw I also noticed it's accessible through settings > my device > call in stock.
Anyhow, instead of moving from CM, have you tried something like this app to turn off the sensor in calls https://play.google.com/store/apps/details?id=com.itsme4ucz.screenoff
or tried to use the Tasker app to toggle it off? might be worth a shot.
EDIT:
There was a mod for this, so you're likely to find something around that will coincide with what your running on yours - see this: http://www.modaco.com/topic/362514-mod-disable-proximity-sensor-cm101-based-roms-only/
