[Q] Screen goes black when making or recieving call after unlock

After unlocking my phone with ChevronWP7 and now my screen goes black during a call and is unusable. The connection is fine, but its like my proximity sensor is doing its job even when the phone is away from my face. I checked and there is nothing physically blocking my sensor. I have to wait for the other person to hang up, then my phone shows the lock screen. I did a reboot but this didn't fix the problem. I don't know if this is device specific but I'm running an HTC HD7 without the software update. Here's everything I did after the unlock:
Prevent my phone from relocking:

Change my theme color:

And lastly installed a couple custom ringtones.
Unfortunately, I can't say after what step this started happening as I didn't get a call until I was all done.
Anyways, If anyone as had this same issue or a possible way to fix it without a hard reset, I'd sure appreciate some help.
Thanks,
JT

the problem is in your sensor.....it's hardware related problem and have nothing to do with software, use your warranty to fix it

[Q] Nexus S screen turns off during/after a call

Is there anyone else having the same issue as I have? My Nexus S screen would turn off during/after a call, sometimes it would turn on when i press the power button and sometimes it would not. I am on stock Android 2.3.4 baseband I9020AUCKD1 Kerne version 2.6.36.7-ge382d80 android-build2apa28 #1 Build number GRJ22. I just got the OTA update the other day. Is this some kind of bug that comes with the update? I hope someone could shed a light on this matter. BTW I am on At&t if that helps. Thanks in advance!

Have den same problem in my phone to
Android 2.3.4
i9023
The screen turn's off when i answer a phone call.

I think it turns off when your in a call so that you don't touch the screen, it can detect you proximity , try on the middle of a call take the phone from your ear the screen should turn on.

I have the same problem... sometimes the display stays black after the call is finished. Then I have to press the power-button.
Rom: MIUI-1.8.19
Kernel: Netachy-1.3.7

I don't have a solution for this problem, but it certainly annoys me too.
It seems that the screen lock timer is still running while the call is in progress. You can verify this by trying to hit the home screen in the middle of the call and seeing the lock screen come up.

I also have this problem and can be very annoying.

This also happens sometimes when I am watching flash video content. As soon as the video finishes the display turns off. The person who said something about the idle timer continuing to count idle time sounds plausible. As soon as the app that was preventing the sleep/lock ends it sleeps immediately.

I think its the in pocket detection... does anyone how to update my kernel from 2.6.35.7 to 2.6.36.7?im not sure how to do?

I think you should just wait, as its going to be March real soon and we should start to see updates for the Nexus S and 4g coming up. If you really can't wait, go ahead .

Are you rooted? Are you on a customer ROM?
If I'm not wrong, you can only update your unrooted stock ROM when you get an official update. (Somebody more experienced please confirm this)
However, once rooted and with a custom ICS ROM there is a whole list of Kernels that can be flashed and each one has the instructions on their respective pages.

you are correct

is that possible:
1. proximity sensor during the call in order to avoid your face accidentally touched the screen
2. over time to lockscreen , like 1 minute , but you spoke 2 minutes ... and then phone automatically screen off ?

I exprienced that sometime in stock GB ROM and custom GB ROM. I have yet to experience it in ICS so far. It could be that when you try to wake the screen up, the phone may actually try to wake up but at that time your phone call may take higher priority -- cpu wise, so it is busy processing your phone call instead. I'm thinking Windows processing priority and I'm a noob.. Or the proximity sensor processing got stuck.

This does actually happen sometimes on my 2.3.6 stock ROM (i9023). Never had problems with turning the screen back on afterwards, though.

[Q] problem with turbo sim

hello
i'm using turbosim .. the phone working with data and everything but its not stable .. it doesn't always receive calls , and it get stuck on black screen and keyboard off if i was talking with someone and he hangs up (then the only option is either a battery pull , or connecting to a charger and then the screen will turn on and i can continue using the cellphone normally
before it freezes , it makes a strange sound , the closest similar sound i can think of is rubbing nylon
i'm using fission 2.4.3 rom
i tried all the connection modes and its always the same ..
i noticed that if the other person hangs up when my screen is on (it always turn off when a call starts) , it doesn't freeze (but the cellphone still make that strange sound).. if i hang up first , nothing happens ..
any ideas ?
call quality is great by the way .. what could be the problem ?

With CM12 or CM13, screen goes black when making calls and is stuck there

This is my first time installing custom ROM's on my otherwise stock Sprint Motorola photon 4G LTE. After successfully flashing CM13 (2016_08_20 snapshot release), I tried to make a call, and upon hitting "call" from the dialer, the screen goes black and stays that way. The only recourse is to hold down power button long enough to reboot. While the screen is black, there is no sound from the ear piece (i.e. it does not appear that the call is connected). Finally, while the screen is black, the phone does exhibit some reactions: it vibrates sometimes if I hit the power button, in other words, the device is still 'on" until I have to reboot it.
After this happened, I gave up on CM13 and flashed CM-12 (the latest snapshot release, from 2015) , and experienced the same behavior.
The call apparently was completed, because the other party received a missed call. However, there was no sound on my end (although there was side-tone, when I breathed on it)
I googled for about an hour, and saw examples of the same behavior on other devices claiming to be related to the proximity sensor (though in those cases, there apparently was audio in the ear piece-- ie. the call completed, and was in progress while the screen was black). This behavior was not observed a few minutes before under stock ROM in the same device (so doubt it's a strictly hardware issue, so doubt I need to open the device and clean the sensor, per some of the suggestions out there).
I suspect the answer is very basic, because I found no similar threads searching XDA.
Please let me know any ideas. I did not do anything about updating my baseband version from stock before flashing the CM ROMs., but don't know if I have to I'm a noob at custom Rom's and just remembered that you had to worry about the baseband / radio version back on the HTC Evo 8 years ago, which was my last time flashing. Again, the ROM itself worked fine-- wifi and 3G/LTE connectivity was a success.
Let me know any ideas.
thanks

After restoring to stock, dialing worked again on the phone, but the behavior on the device was different from two other photons I tested next to it.
In the stock ROM, the call connected, but the screen turned off immediately upon hitting "call" (even when the phone was on the desk). You could get the screen back (in stock only) by hitting the power button.
In my other two photons, the black screen does not kick-in immediately. So it does appear it could be something having to do with the proximity sensor (i.e. it's always engaged). I don't have the skills to confirm. I am writing-off this phone for now, and have a different device (so not a high-priority thread at this point), but let me know if anyone has any ideas. Thx.

There's a way to validate if the prox sensor is working - zDeviceTest in the Play Store will test all of the hardware, and it will also show the metrics each piece of hardware is receiving - the prox sensor being fairly simple, it just identifies if an object is "near" or "far".
I always recommend making sure everything works in the stock ROM before flashing anything custom - as you need to validate everything works before making tweaks.

My advice is the same as arrrghhhs. (This name really looks like it was typed with a Photon Q with some characters repeated by the device >.>)
I noticed that my proximity sensor sometimes "stuck" to near (I use some different app [SatStat] so it shows 3 cm or 100 cm instead of near/far). Winking a little above the sensor helps sometimes. But your problem sounds like a defect.

Question Poco X3 pro frequent crash after MIUI 14 update

Hello,
recently after decided to update to MIUI 14, my Poco X3 Pro crashing when on the call or video call, but weirdly enough the phone doesn't even crash when gaming or doing any multitasking it works just as it used to be, its been 4 times:
- at first it was only the screen turned off but the rest like sound when call, microphone, and touchscreen are working but the display stays off, the display turn on it again by itself after a few minutes this happens 3 times until now
- the last one was hard brick, the device turn to white with a thin horizontal line, restarted by itself and then it wont turn on at all, even the charging wont work, but i can boot to fastboot, and then try to boot it to miui via fastboot and now it turn on and work as it suppose to be (not yet trying to make call since i dont want it to crash again)
Now i dont know does this could be caused by neither software or hardware, do you guys have any idea?
Thanks!
