[Q] No blank screen during call? - Desire HD Q&A, Help & Troubleshooting

Since a few days my DHD does not go blank anymore while making a call? I searched all the possible settings, but can't find anything. Google doesn't show anything either..
When normally while making a call the screen goes blank, it stays on now. So the weirdest things happen during the call..
Anyone any ideas?
TNX!

Are you rooted? If you are you can use the proximity recalibrator tool. Search for it in the Development section.
If you arent, please inform us and we'll do the best we can to help.

Nope; not rooted, standard device with 2.3.3.

Maybe your prox snsor is broken. Download 'proximity screen off' free from market.
A cool app and also a good way to check the prox sensor. See if the sensor is working.

Ye it seems like the sensor is broken. Its a little thing next to the earpiece. Nasty little bugger.
But yes first download that app and see if it says anything.

Installed it, push "start services" and thats all thats happening...

You may need to go into settings. Select.to turn off device when sensor covered. Cover prox sensor for time set. See if it asks for perrission to turn off screen. If not check settings. If it still doesnt work sensor is broken.

Proximity sensor issue...please help

the phone screen should turn off when in a phone and close to my ear due to the proximity sensor
but the screen doesnt turn off....i dont know why
its a stock desire hd with the recent gingerbread update so its not rooted.
any ideas for troubleshooting?
its really annoying
i have an app that tested the sensor and found no issues (ie, it measured me moving my finger on and off the sensor without issue)
no root, cant help much, no custom kernels
iv always had the same issue, even with Lee's rom installed, the proximity sensor never seems to pick up at the right time.. is there any way of calibrating it?
There was an app on xda somewhere for calibrating the dhd sensor. Try a search on here and try Google. Think it might be a known bug with some dhd.

thanks, yeah i read that thread, but i'm using GB stock, and unfortunately its not yet supported by that app.

[Q] Proximity sensor calibration

Hey,
is there any way to calibrate the proximity sensor one the One X?
For some reason my proximity Sensor needs very high brightness values to activate the screen again, when calling. This happens on every ROM I use, even stock. Does anyone else have this issue and is there a solution? I've been looking for a while now but only found solutions for other devices. Help would be very appreciated
Are you taking about ambient light sensor?
Proximity sensor is sensor made for distance detection.
No I actually mean the proximity sensor. I know it shouldn't be depending on light but it does. I don't know why. First I thought the sensor is broken, but if there is enough light it reacts to movement. If not I'm not able to get the screen back on until the other person hangs up. Its really weird. Sometimes even the little red light stays on. In the DHD forum i saw a thread about someone who developed an app to recalibrate the proximity sensor, so i thought this could also be done for the HOX.
For your knowledge, the proximity sensor on One X is kind of binary type (return 0/1;object detected /none). There are some sensors test tool offers on play store, you may try them out..

Ok. I did that already. Same happens there. Thats why Im not sure if its malfunctioning or just needs to be calibrated.

i had exactly the same problem. You can fix it with http://forum.xda-developers.com/showthread.php?t=1882725 this patch. All you need is a custom rom with init.d support. Cheers!

[Bravo] A working fix for the proximity sensor in-call problem

All credits go to ginodp and the users he mentions for finding the solution for a similar problem on the Desire S. Here is the link to the original thread.
The problem: An awful lot of HTC Desire phones have a malfunctioning proximity sensor which constantly reads 0.00 cm i.e. complete obstruction. This causes the phone to blank out the screen during a phone call but never light it up again. Trackball wake and other methods generally don't work; inserting a headset sometimes works, but obviously it's not a workable solution.
The solution: The solution is disabling the proximity sensor. To do this you will need a rooted phone. Edit the file \system\build.prop with any editor that has been granted Superuser permissions by adding the line
Code:
gsm.proximity.enable=false
at the end of the file. Done! now the phone's proximity sensor is disabled and the screen will not blank out during a call, enabling you to end it at will.
I don't understand how to do that, could you give me a noob-proof rundown? Sure thing!
Code:
1. Have rooted phone.
2. Download BuildProp Editor from Google Play.
3. Press "get su prompt"
4. Gran Superuser permission.
5. Press menu, Add property.
6. In "Type in keyname" type gsm.proximity.enable
7. In "Type in value" type false
8. Press "Save value to file".
9. Reboot phone to let changes take effect. Done!
Any further questions or ideas on how to make this easier or better are much appreciated.
Again, all props to original finders!

Is proximity sensor not work on all Desire (Bravo) phones?
Oh great. So now you can hang up the call by accident with your ear.
Sorry, but disabling the proximity sensor is plain stupid?!
In my old winmo6 days u had to manually press the orf button to shut down the screen.
I guess with this u can do the same. Use off button instead of the sensor kicking in?

Unfortunately my proximity senor is brocken.... I have tried everithing to disable it but no success.
Now is in service center... waiting for repair... new sensor:crying:
Nikog
Yeah well why don't you try to enter a number after the screen goes dead for automated services that depends on it...
This is meant as a fix for ppl that have faulty proximity sensors. Not for fully functioning phones.
IF I had a faulty one this would be perfect.
Press off button after you have answered and your ear won't press a single thing. Press off again and screen goes on.

The alternative is not being able to end calls, which kinda sucks ass. I wrote that in the OP though, so what exactly is your objection?
My solution was...
I thought that I have the same problem but after all I found out what caused it - it was a low-quality faceplate as I changed it. After I put a new original one the problem was gone.
Big Thank you!
A big thank you!!! Just the buildeditor is huge, let alone the good data!
Thank you!

Sometimes, signal stops, when covering proximity sensor!
recompiling kernel with modified drivers also helps

I've tested several solutions found on the web, but none of them helped
(using Screebl, gsm.proximity.enable=false among them)
I ended up modifying kernel drivers (in case of my htc desire i was drivers/input/misc/capella_cm3602_htc.c)
I changed capella_cm3602_report routine to read:
Code:
static int capella_cm3602_report(struct capella_cm3602_data *data)
{
int val = 1;
D("proximity %s\n", val ? "FAR" : "NEAR");
/* 0 is close, 1 is far */
input_report_abs(data->input_dev, ABS_DISTANCE, val);
input_sync(data->input_dev);
wake_lock_timeout(&proximity_wake_lock, 2*HZ);
return val;
}
ie always return FAR instead of NEAR.
Then I recompiled the kernel, and reflashed zimage with fastboot.
Now it no longer locks the screen during voice calls.

proximity sensor always on

Hi guys m facing a strange issue. I have observed that sometimes my proximity sensor remains on. I tried to find out the app causing it by Force Stopping each app one by one but that doesn't solve the problem. .
I am not using any motion like quick glance which uses the sensor or any other app like turning the screen on off (eg smart cover etc)
only a reboot fixes this issue but after sometime (say few hours or 1-2 days) the sensor turns on. . Can you suggest me what else shall I do? coz m observing more than normal battery drain in stand by mode. . Please help!

Try turning off "quick glance" under settings--> motion.

I too have noticed it and posted it on a thread also
I also notice this..only now i came to know that it is proximity sensor..will appear as a dim red right and if it stays on, it turns off only if restarted..might be a bug..should we report it to samsung so that they will fix it in updates?
I have noticed one thing that after 2+ or more (random) days of usage if I receive/make a call the sensor doesn't turn off. .might be this is a s/w bug. .but this is what I have noticed after closely monitoring my phone. .

I've noticed this too! Didn't know the dim red light was proximity sensor. But i've noticed it only twice (with battery below 40% on both occasions).
Viber has a known bug that cause the proximity sensor to be always on. If you uses it, u need to update to the latest version i think its v2.2.3.109.

Even though I first got this proximity sensor bug after I turned on "increase volume in pocket" (only 1 time so far), I'm pretty sure it's not related, because I did a few tests and as far as I could tell the phone increases the volume based on its position (and possibly movement) in the second it receives the call. If it's vertical (like in a pocket), or on its side (like in a bag), when you get a call, it will increase the volume. If the phone is horizontal, like on a table, and starts ringing, the volume doesn't increase, and it won't increase even if you pick it up and move it around while it's ringing.
I also thought initially that it uses data from the proximity sensor, but I tested and it doesn't care if it's covered or not when the phone rings, it appears to use data from the accelerometer/gyro exclusively.
I'm try turn all motion off right now. Let see if it can solve the problem
I have the same problem.
I resolve it by pressing volume up + home + power.
Let it restart and so far after about 1mth+ did not encounter this issue any more.
Hope this help :fingers-crossed:
i have the same problem
all motions are off
and still have it random....only restart to close the sensor

All apps wont auto-rotate

Every app on the phone wont autorotate... I have autorotate turned on but its not woking.
Sent from my HTC One M9 using XDA Free mobile app
Not all apps will switch to landscape mode. This is app dependent.
If you are in a app that you know should auto rotate but is not, please see this thread: http://forum.xda-developers.com/one-m9/help/gyroscope-t3095820
i got the solution, this is crazy but works...
go to help app(the one htc pre-installed on ur phone)
then go to hardware misbehaving?
hardware diagnostics
G-sensor test.
test it once , or twice. let it say failed.
next from that screen tap on calibrate g sensors
do the calibration on a flat surface
go back and do the test. this time it will say it worked.
and acctually, it did work, my autorotate , riptide, dot-breaker, everything based on gyroscope sensor is now working fine !!
