[Q] Black Screen when starting a Phone Call, and finishing how to come back?

I've in my htc hd2 the Dutty FAM v6 HD2 rom, and I was trying an Android build (mjdejay Clean 2.2)...
It seems everything runs ok, but I've done a Phone Call, screen automatically got black (Off, like in WM 6.5), but when i finished the call, i cannot get screen on again... I've pressed all the buttons, but nothing appears to happen...
If i plug usb wire into HD2 it comes back, and if i do an incoming call, i can take it...
Nobody has got samething? Thnx!
UPDATE: I think that my HTC HD2 has its proximity sensor broken...

A number of members have the same issue. I do. But not always. No fix for the moment.

also , get a better rom (even tho i have a mdj build myself)

Gee at least you didn't say buy an android phone. To say take it away from your ear is redundant. And to try a better build is just as bad. Why did you even waste your time replying?

this happened on my phone occasionally (though i haven't experienced it yet with mdj s4 kenel), anyways...
if the screen stayed black after moving the phone away from my ear, id cover the light sensor briefly with a thumb (or whatever!) BEFORE pressing the end call button, this always restored the screen. may work for you?

Hi. I have same problem. Now I have MDJ Froyo Sense 2.4. It is very frustrating all roms what i tested has this problem... Is any solution? I tried to disable automatic display brightnes but without success...

Just to make you feel you are in company I have this issue too. It is the single biggest pain in the ass about android and it isdriving me maaaad.
Still better than rocking WM though.

Same problem here, about 90% of the time. It's most annoying when you're on some automated service that asks you to press a number and you can't get your screen on to bring up the dialpad!
Rest assured though, pressing the end call button does indeed end the call. Just leave the phone alone for a minute or so afterwards and it appears to back to "normal".

Finally i have found a workaround
Hello, after many tests i have found good workaround. It is very simple. Download from Market: "Speaker Shake" (there is avaible a free version) and install it. Then set it like on my screenshot. (important setting is "Speaker Always ON"). Now when you start a call, this app automaticly turn on speaker - this event wake up your phone and then is end of your "black screen". After this you can again switch off speaker in time of call...
Sorry for my bad english. I hope that it will help to you..
I use MDJ FroYo Sense Clean v. 2.4 [kernel: MDJ S6.1]

Thanks. I will give Speaker Shake a try.
Just a little happier right now as others have this issue and that it is just not an issue with my phone.
I am sure it is just an incompatible driver somewhere. Never noticed it in prior builds but with new builds it happens. But not always. But I did notice if I am able to select speaker then turn speaker off the issue doesn't happen. But then the screen does not go black when I put it to my ear.
To me this is a much bigger issue than data freezes. Makes using my phone as a phone almost unbearable.
Hoping someone who knows how will look into this issue soon.

Tried Speaker Shake.
Calls are automatically with speaker on and screen stays awake. However after turning speaker off the screen goes black and won't turn on again.
Nice fix if using speaker ALWAYS but still doesn't help for normal calls.

I tried it many times and this issue "after turning speaker off the screen goes black and won't turn on again" i had only once.
I have changed this app and now it turns speaker back to normal. You can try it. For my is it now best solution how to avoid black screen....
And i forgot to say that you need to have switched off automatic brightness of display..

Has anyone tried covering the light sensors for a few secs?
Not the best solution but it always works for me, can live with that till it gets sorted.

It doesn't work for me...

Hello. I have a problem with unlocking the phone. When I lock the phone and try it again to unlock the screen lights up only in black. Sometimes it takes a second, sometimes longer. You have the same problem? Any fix?

Thanks petapen. I will try your modified application.
Still wondering what the issue is here. Newer kernal issue? I believe I am still running hastarin 8.3.
Edit: And for other poster.......covering light sensor or exposing it to bright light does nothing once it turns black.

If anyone have any another solution. Please let me know....

black screen

Screebl.....

If you haven't disabled auto brightness, do that. Secondly, some roms require a person to press the "call" key to wake the phone up.
Lastly, try a different rom, just remember to shut off auto brightness. I wish they came with that defaulted to off anyway.

Bumping this thread to keep it alive. Had a 50% chance of keeping the screen on, in froyostone v3.1. But it always came back after hitting end call key.
With MDJ FroYo HD v.4.3 the screen goes black everytime. Even after call the screen does not come back on. Only work around is to have someone call my phone and reject the call with the call end key. Then the screen turns back on.

[Q] Disable Proximity Sensor

Hi,
is there an option for android-HD2s to disable the proximity sensor? I'm sick of the behavior of my device that the screen doesn't turn on again after making a phone call, taking out battery isn't a very useful option...
I already tried the Recalibrator for the sensor (originally for DesireHD), it worked for a few days but now again i've got the problem...
Therefore i'd rather have the screen turned on during the phone call, than having a blocked phone after the call..,
Do you know a solution?

hi, I guess you are using Desire HD rom. If is so I fully understand you. Those build s avery big and laggy. After trying many,many rom s Iwent to this one>http://forum.xda-developers.com/showthread.php?t=931126
The screen turns on , everything work s fine. And it is crazy fast. Believe me, you will love android after this.

the best DHD Rom is Core Droid, in 1.3 the sensor was good, but in the actual 1.4 its bad again, try it when the next version is out. its very fast and nice skinned, also always good updates like the controls widget in the notifications bar.

Are we talking about the rom for hd2??is there anyone who can help us on the same problem?

I do this that way http://forum.xda-developers.com/showpost.php?p=16008095&postcount=4

Display goes off during a call and doesn't come back

Hi,
I have Xperia arc S. Recently it is behaving in a crazy way during a phone call.
when I call or I receive a call, and put the phone on my ear, the sensor works and get the display off which is normal... but what is not normal, is that many times the screen keeps off and It doesn't get back on.
It's more happening when I am outdoor.... and in many times I need to remove the battery to get it working again.
does any one face the same behavior? any suggestions?
Thanks alot,

I used to have the same problem. It's normally one of two things, either the sensor is obscured(eg some cases, or it's greasy) or low ram. If it's the sensor then it would be pretty obvious, with the ram issue then you can try a ram cleaner from the market, or a ram management app/script, or a custom rom(these all need a rooted phone, with a custom rom/kernel you'll probably need your bootloader unlocked).

I have the same problem. I haven't found a solution, but in my case the screen will return when the call ends. I found an option in the phone to use the power button to end a call. That allows me to end a call when the screen won't activate. I can then push the middle button and the screen comes on.
I have investigated the sensor suggestion, but I don't think that is it. The screen will work perfectly in normal light conditions, but has problems in either low light conditions or outside when it is very bright. I don't think the latter case would be an issue if it was due to a blocked sensor. It is more like the software not being able to distinguish a change in light level either due to insufficient light or being overloaded by too much light. I had hoped 4.0 would fix it, but it hasn't.

Are you on a Custom ROM?
Or tweaked the autobrightness with a tool?
I only had this issue when i was on a Custom ROM that had bugs...
So if its official ROM, try wiping it...
Otherwise it could be just a bug of your rom, and you need to get an update if available

I think its a bug on stock ICS 4.0.4 because I had this problem too and only pulling out a battery would fix this. This happened to me only on pure stock unmodified ICS.

try another Rom, i guess it is your rom's bug

[Q] In-Call dialer unresponsive...

So I have seen this issue on multiple forums, across multiple roms/devices, but can't seem to find any solution.
I have a LG G2 on VZW (VS980) currently running AOKP 5/24 nightly (but I have had this issue for months now).
When I make a call, the in-call dialer interface is completely unresponsive. I can't hang up, open the dial pad, speaker phone, mute, etc... the only way I can hang up is to hit the back navigation button and then pull down the notification and hang up that way. I am running PA micro gapps, but I have had the same problem with other gapps as well.
Does anyone else have this problem or has found a solution?

Bump. Really looking for any ideas on how to fix this.

I'm in the same boat here. Would really appreciate if someone could provide a fix.

I fixed my issues by flashing the "Google Dialer" in this thread

Same issue - can't use the touch keys in the dialer while in conversation in LG G2

Thanks a lot for posting your workaround.
I have exactly the same issue - I can't use the touch keys in the dialer while in conversation in LG G2 D802 (Intl).
However, the Google Dialer is an old app that got replaced by Hangouts Dialer.
Did you switch to Hangouts Dialer, or you stayed on KitKat 4.4.2 with the old Google Dialer from the post you provided?
By the way, I posted issue CYAN-6090 in the CyanogenMod JIRA in order to try and get resolution to this issue.
Are there any other users with this issue?
Did you solve it somehow?
note: sorry for not posting links. I have that annoying new user limitation...

there's a similar issue - LG G2 screen turn off and goes blank during conversation
It seems that there are two similar issues in LG G2 which are both caused by the proximity sensor during conversation:
The screen stays on and the touch buttons in the dialer aren't responsive.
The screen turn off and goes blank.
(This issue was already reported by @madafis here)
In both of these situations the only quick way to end a call is to pull down the status and notifications bar and hang up from there.
Thanks to @Bam9 and @EtherBoo , who suggested to clear the proximity sensor from the outside and squeeze the top left corner of the phone, I tried to clean it and put some stress on it - and it worked!
I have a glass screen protector (which don't block the proximity sensor), and I am rooted and using CyanogenMod 11 ROM.
I used ioroot to root and AutoRec, which comes with TWRP 2.7.0.0, to install CyanogenMod ROM.
However, going back to stock ROM (in my case, LG G2 D802, it's D80220C) won't help since the issue still exists.
What I'm sure is that it was pretty much okay in the beginning, and the situation became worse and worse - occurring randomly, until it arrived to a situation in which I can't use the phone properly during conversation.
Now that I discovered that I can put some stress on the proximity sensor it seems that I have a hardware rather than a software issue.

[solved] Screen Blacked out after making a call?

Hello,
I have the i9505 and i have flashed it with [ROM]【4.4.4】Google Play Edition 07-17-2014 - Pure Nexus Edition build now available by @Danvdh and i absolutely love this ROM and works like a charm but there is one thing i am having issue with and i cannot say its a bug as looked over his thread but no one has mention it. i can comment or post in the developer thread due to the number of posts i have, however i come here to ask for help.
When I make a phone call, my screen goes completely black and when i try wake the screen up, it would take multiple times and sometimes i have to take the battery out. The call somehow runs in the background, so if i managed to wake the phone, i have to pull the notification down fast to hang up and this is pain in the neck.
I suspected it could be the proximity sensor in my phone, i have no cover or screen protector, i cleaned the screen and still the same. so i ran few tests to check the sensor. phone detects the sensor but it doesn't do anything.
Thank you in advance

after many research, i have found the issue and its fixed.
http://forum.xda-developers.com/showthread.php?t=2569141
you will need to reset the proximity sensor depending on the values. i can say all working now
