No Wake-up after phone call

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.
http://forum.xda-developers.com/showthread.php?t=946012
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 ???

Screen stays off throughout the call.

Hey friends,
I am facing this problem while making calls that as soon as I press call button or receive button(while taking call) the screen turns off n stay that way till the call ends.
I have tried pressing all hardware buttons,even moved the dvp awayfrom me n into direct light but to no avial.though it did turn on once or twice out of twenty times.
Did anyone else experience this? Any suggestions are welcome..

Do you have a screen protector or case that is obscuring the light sensor or proximity sensor? My first guess is that something is obscuring one or both, because during a call the screen being off is a feature.

screen stays black/off during call
The screen stays black during a call and this happens ramdomly. I have a dell venue pro a t mobile phone but it is a pre release so it works on att 3g and all. I have switched the sd card with no improvement. I have ordered a transender 32 gb sd that I haven't received yet. The firmware version 2250.1400.7004.025 hardware is 112.576.2.0 radio soft 2.2.50.14 radio hard 8250. I have been unable to get any of the hardware keys to hang up the phone which if I get voicemail or something means I have to power the phone down to get the dang thing to hang up. Sometimes it works fine but I cant find a commonality software or hardware that causes this. It happens right out of the box so even after a software reset it can happen. Is there any solution for this issue?
I can't understand why the button on top doesn't hang it up.
PS I got this phone for free and I got ripped off LOL

wow just got a replacement phone today and im having this problem, As soon as I go to make a call the screen goes black and cant do anything on screen during the call, so i cant enter my password when checking voicemail

I think it's related to the proximity sensor. When you put the phone close to your head, the screen switches off. When you move it away, it will switch on - most of the time .
If it stays black, have you tried tapping the power button on the top of the phone? It switches the screen on without disconnecting your call.

A coworker got a replacement the other day(they send a refurb) phone and it had the same problem. Had to go through Twitter to get Dell to send him a new retail phone since they had send him 3 refurbs prior and they all had different issues.

This is just a general statement regarding phone proximity sensors. I have had multiple phones made by different manufactures that experience this to some degree (including the Venue Pro). One thing that I have noticed is that if the phone goes from your face directly into a bright light (outside is most common) it will keep the screen shut off but if the sensor is somewhat shaded it will resume normal function.

I got the same problem too and while it may be a proximity sensor problem, it is not controllable on the user's end. Unless the phone call disconnects magically, a battery pull is necessary.
I'm gonna be on my third one soon and I hope that i won't face the same problem.

Yes i recently got a new refurbed phone and this problem has arised. Complained to Dell and they are going to send me a Brand new DVP. I see a lot of people having this same issue with the refurbs. Currently Dell is out of new DVP due to them upgraing the firmware, so I have to deal with a broke phone till the end of August. Talk about a dissatisfied customer. Im thinking about selling this brand new unit when I get it, hopefully Toshiba has their device out by then

This is a Proximity Sensor issue. You can fix it though in the EM app. You can adjust the sensor readings and the phone will function like normal. Let me know if you need the values or a step by step!

A step by step would be awesome. I like being able to see the screen during a call.

1) Get the EM app, if you dont have it dial ##634# into the dialer
2) Get into the advanced menu by double tapping the black area and typing in "qwertyuiop"
3) Select "RD test", now enter *#6336# in the box that pops up.
4) Select "Sensors", and the "Proximity Sensor Config"
5) Set the following to these:
LED strength - 1
Diode select - 2
Pulse Count - 43
6) Hit set and then you are good to go!
I have noticed that one of my DVP's needs to have this put in again everytime I reboot the phone, the other saves it. Just an FYI for ya!

I get to step 3 and when i clock on RD test, I am prompted with a white box with blue trim and an X at the top right. can you advise on how to proceed?

Oh yeah, Im sorry I forgot that part. Enter *#6336# as the password.

When I dial *#634# it says thic code is not supported.
What does that mean?
I put in a different number combo before and it put me in the EM screen

[Q] Proximity sensor funkiness?

This has been happening pre and post Nodo on my focus. If i'm on a phone call for at least a few minutes, then pull the phone away from my head, the phone's display should become active, but it isn't.
Anyone else having this issue or is it time to exchange the phone?

I have the same issue also it seems like I have to press the power button a couple of times to get it back.
Sent from my SGH-i917 using XDA Windows Phone 7 App

I'm also having this issue. Anyone remember if ther were having it pre-Nodo? Just wondering if the update changed something.
Regardless, it's a bit of a PITA.

I experienced this after having to replace a cracked screen. I just recalibrated the proximity sensor with my finger about an inch away and it worked fine.

How did you do that?

Yeah, ditto that - how do recalibrate the sensor?

Samsung Diagnostic App.
http://forum.xda-developers.com/showthread.php?t=839154
I was pecking around the screens months ago, and there was one bank of tests (multi-touch, red, green, blue, white, battery, etc, etc) that allowed setting and viewing the proximity sensor.
I remember playing with moving my hand closer, and further and watching it change from sensed to clear.
Sorry, can't remember which codes now.

I used the Wiki:
http://forum.xda-developers.com/wiki/index.php?title=Samsung_Focus
LCD Test - *#0*#

Ok, mine says No Detection. Is there anyway to set the value?

One other thing to note, about the samsung focus specific update regarding disabling the touch sensitive buttons while in a program, that also isn't working for me either. Not sure if they are related, but thought I'd throw it out there.
And as far as calibrating goes, not sure it would help since the problem only occurs while I'm on a longer phone call. On short ones the proximity sensor works just fine.

If you move your finger closer to the sensor, it should eventually change to Detected. The "set" button at the bottom should set the proximity sensor to the new distance. Mine is around 75.

Mine says No Dectection. It has Prox Sensor: XXX I've taken my entire hand and covered my phone. NOTHING. When I push SET, It says ProxThreshold :0. Is there anyway to set it manually?

samsung focus post nodo
I believe the prox sensor issue is happening post nodo, I have never had this problem prior to the update... I have been able to fix it temporarily by pulling the battery and starting it up... don't know how long the fix works... got to do some testing... I am wondering if its a power thing as the screen wouldnt work when you plugged it in to power and had on a soft surface....

Still nothing. I didn't want to hard reset since I have Chevron installed. For some reason I did four updates on my phone and don't have a single backup. If I hard reset I'm S.O.L. with Twin Blades and other homebrew apps

What value does it show when you press the Reg button?
I've had issues with my earring tapping the screen while I talk and I had it fixed before NoDo, but the values reset when it was installed, they also appear to be different values now as my screen got supper finicky after the update. I was constantly hanging up or scrolling through multiple pages of stuff with my ear and you could see the screen turning on and off. I ran the proximity calibration while holding my hand in front and set to it to 1.
If it shows xx have you tried setting the value with nothing in front of the phone to see if it will at least zero out?

It has a big red box. It says No Detection. Prox Sensor:XXX Do I press Set or Reg?

another thing is wrong
seems like my light sensor is fried as well... I am starting to wonder if it's because of bad placement of the usb port... both lay right in front of the port, can't imagine pluging in and unpluging the phone would help if the sensors are right in front. I can't get either sensors to work anymore, even with a battery pull... does anyone else have this issue? goto the diagnosis menu and type
*#05#
you should be able to run through all the tests, I skip the feedback loop... Start at 1 and work your way through.
My Prox sensor says, no sensor XXX, and my light sensor is stuck with a value and will not change even when I cover the sensor... looks like a warranty replacement... how does this work with a sd card installed, the official WP7 ATT certified 8GB? Anyone else have to do this?

Proximity sensor problem! [SOLVED!]

Hi everyone, welcome to the next thread of mine where I would like to share with you an interesting case of a'faulty' proximity sensor. The issue with the sensor started a few weeks ago (I own my defy for a few months) and the problem I had with it was that sometimes during I was making a call the screen was not being turned off, and more whats more annoying - the screen was never turned on again after finishing the call.
I do not have a screen protector and the screen glass is original.
I downloaded an application that showed the state of the sensor and after a many examinations i found out that many times the sensor does not distinguish between the states of being covered and uncovered.
I tried everything - factory reset, clean installations, different ROMs - nothing helped. The only thing that helped a little was a tweak availale in the CM7 ROM by Quarx (not available in the STABLE CM7 though!) in the screen settings menu -which forced the screen to be turned on after finihing a call, and I could also set the power button to end a call in the accessibility options. So this helped but did not solve my problem.
Fortunately, after many questions asked on so many threads, the user monecafe PMed me with a link to a video where its clrealy shown what is the problem and how easy it is to fix it!
without sayng more - here is the solution for anybody experiencing this issue:
http://youtu.be/uMk1S90MjbY
I hope this helps !
& a BIG THANK YOU to monecafe who sent me this video

this is great, very simple solution but...
how will that affect the water resistant feature of our defys?

try turning off auto-brightness
posting to say... try turning off auto-brightness (worked for me)

I used to have this problem. Stable CM7.2 solves this issue for me. I used to get the screen to turn on before by just rubbing the area with the proximity sensor with my thumb as if it was dirty.

i still have this problem. , after the Waterproof failed with my phone ( i dont leave it in water, i just wash it !! the proximity sensor failed too when i make a call screen is black cant see anything..so my question is if i change the screen touch proximity sensor work?? or its on the board ? where is the proximity sensor place?..how can i solve this problem by myself.
i saw the video but not solve the problem..
i back to stock ROM _there_ if i press power button the screen back but in coustoms ROMs the screen off not back till remove the battery!! any software make screen on at call and disible the proximity sensor ?
thank you inadvance

I also have problems with proximity sensor. With pressure on the screen where the sensor is located it is working again.
So I can believe that changing the screw pressure might solve the problem. But what is the initial reason for this? It is not a pressure sensor!

Hello All, I've been using the proximity sensor app on my DHD for quite some time now... LOVE IT ! However, now when I open the app & tap on Start & cover the proximity sensor on the phone, there is NO RESPONSE... Meaning the msg stays FAR... It DOES NOT change to NEAR.... Can anyone help me out ? CHEERS !

Hello all,
My 1st post. Pls i dont want any lectures on chinese clones, thats what some of us can afford! i Just got a Star N8000 which is a clone of a Samsung Note. I LOVE the phone. The only problem is that when make a call lets say to check voicemail, the screen goes black, the proximity sensor flashes continuosly (small red flashes) & nothing i do brings the screen back unless the call ends from the other side or i take out the battery. I dont want to root my phone just yet. It uses a tmd2771 proximity sensor. HELP! anybody

Solution??

Found a possible Solution suggested by a supplier on Amazon;Switch off the phone - Hold power button & volume down button
simultaneously to bootinto factory testmode - use volume swith toscroll thru to 'test report' - select with the home key - scroll down to 'PS calibration' - select it then scroll to 'do calibration' let it do the calibration till it gives OK.Go back to 1st menu & reboot.
Was only partially successful forme, it may work for you.

I have the same problem with proximity sensor tmd2771 my phone is htc one x clone (E1911)
i make the calibration but its still have the problem it saws me the sensor goes up and then goes down from itself and at the calls the screen goes black and opens again from itself is there a solution for that???

Is this applicable for Motorola Defy or for the Chinese clone?
I tried this on my Defy running JB 4.1.2. I cannot get into the "factory testmode" even after pressing the VOL down key at boot up.
I just get a screen with an exclamation and the android bot.
Nothing happens after that.
BTW: What size of screw driver should I use to perform the trick in the video posted by the OP.

D800 Screen keys pressed while on call - build.prop mod?

I´ve searched this forum, but found nothing like what I am facing. As per title, whilst on a call, with the phone on my ear (left ear usually, if that means anything) the on screen buttons are pressed, because I usually end up with the call on hold. Other times, it finishes the call, other times it dials a number from the contact list...Here´s a list of what I have done so far with no success:
1. Calibrate proximity sensor with apps
2. Use hidden menu to test functionality (it works as advertised)
3. Calibrate motion sensor
4. Full reset of the phone
5. Clear dalvik cache
6. Test sensor functionality with app (again, works as it should). It detects when my hand is covering the sensor and it detects when my hand is taken away from it. Instantly. Also, left my hand covering the sensor for a while (simulating a call) to see if at some point it stopped working, but no, the darned thing worked as it should.
I read somewhere here that a mod on build.prop might help (it has to do with the delay time of the proximity sensor) but since the post didn´t explain the exact setting, i googled it, and found 2 settings that might apply:
1.) ro.lge.proximity.delay
2.) mot.proximity.delay.
Neither of them is in my build.prop file, so, the questions that pop to my mind are:
1.)Which one of the two would affect the described issue? Apparently those settings are modified by users that had a problem with black screens after a call or with long delays for the screen to come back after taking the phone from their ears to use the keypad, but no post that I read indicated which one of the settings influenced what. I have the feeling that one of them is for the proximity sensor to "kick in" while the other controls how long does it take for the screen to come back after the proximity sensor stops detecting your ear.
2.)Can I add that setting to my build.prop without risking a bootlop or a brick?
As the title say, I have a D800, with official AT&T 5.0.2 ROM, rooted, with stock recovery.
Any help would be highly appreciated. As you can imagine is terribly frustrating that I cannot use my smartPHONE as a PHONE because of this!
Thanks in advance!
Frank.

a small, shameless bump!
