On calls (touch)screen is disabled and won't turn on until call is terminated - Nexus 5X Q&A, Help & Troubleshooting

When I make or receive calls the screen turns black and the touchscreen is disabled. I assume this is to avoid accidental keypresses with my ear or something, but my phone doesn't leave this mode until call ends.. I assume it would switch on screen/touch when leveled horizontally, but it doesn't.
I cannot end the call or do anything while the screen is disabled.
The only thing that works sometimes is to double press power button to turn on camera (thus enabling screen/touch), but it is no reliable method.
Sometimes, if I call a person not taking the call, without mailbox or automatic termination of connection, I have to reboot to phone to end this.
Any idea what I can do? Can this supposedly helpful behavior be switched off or fixed?
I am on Android stock 8.1.0 (OPM6.171019.030.H1, Aug 2018), rooted with most recent Magisk.
This bug is driving me nuts, so Thank You for any ideas or help!

Is there anything blocking the proximity sensor (below the right of the speaker)?

Not that I know of. All is as normal as can be.
But right now, it seems the "trick" with the camera double click works more reliably (>50%) than before. Whatever reason..

If you've had the phone apart recently ... check proximity sensor. There's a little rubber piece tends to fall out.

Did You applied a screen protector recently? I had the same issue because of screen protector was covering the proximity sensor

No in-call curtain in TP2

Hi,
I'm using an original ROM for TP2 with Manilla 2.1.38158.2 (as shown in Settings | About).
AFAIK this version should include the "in-call curtain" functionality, on which the call buttons are locked during a call. However, I see no sign for this anywhere.
Does anyone have an idea how this feature can be turned on, or how do I add it?
The curtain is unnecessary. Your device as a proximity sensor that turns off your display when you hold you face it. You don't need the curtain to lock the buttons. When you move the device away from your face, you probably want to use the touch screen so it turns back on.
I usually talk using a Bluetooth headset while the device is kept in my bag or pocket. The proximity sensor should theoretically detect that the device is covered and keep the screen off, but it often fails to do so, allowing random buttons to get pressed.
S2U2 doesn't solve this either, as it keeps the device unlocked during phone calls. There's TouchLockPro, but I don't like the way it works.
Have you tried CSDEVCTRL? I recall it allows you to lock the device during and after a call.
Yes, I found it in one of the forums here a couple of weeks ago. For some reason it didn't keep the device locked during calls, though specifically configured to do so. I haven't looked deeper into that, since I thought that the supposedly built-in curtain would do.
BTW, a simple test shows that the proximity sensor is completely useless for this scenario. I put a small object on the sensor, locked the phone and turned it off. I then called it from another phone and answered using the Bluetooth headset. Although the screen was blocked with an object, it was completely unlocked and could be pressed. The proximity sensor turned the screen off only if a movement was detected towards the screen, and not when something was already blocking the screen.
I repeated this test several times with the phone in a bag. I locked it, called, answered using the Bluetooth headset and tried to press against it from outside the bag. In every single time on-screen buttons got pressed.
As a matter of fact, the TP2 is way worse than the original TP in this sense. In my previous TP I could answer a call using the headset, take out the phone (carefully so it won't hang up by a screen press), lock it again and put it back in the bag/pocket. Now with the TP2 the proximity sensor wakes up the device unexpectedly, so I can never keep it inside anything during a call.
There is a shareware Pocket Shield which provides a screen curtain. You may have a try for your TP2 at this link:

I tried installing the InCallCurtain from my Touch Pro ROM and it does not work with the TP2. It is a different dialer so the calls for the curtain may not be in there.
My phone has no problem turning itself off when it gets near my face. Why would you want a call curtain?

Did you read the thread ?!
Thanks Angler, I just tested Pocket Shield. I must say I like the progress of this program since the last time I tried it.
I won't use it as a general lock utility because of a severe issue: for some reason my Bluetooth headset loses the ability to answer calls while it's locked. I click the headset button, the ring sound moves to the headset, and the call is not picked up.
I'm thinking about only using its curtain feature - use only the protection during phone calls without locking. This seems to work, however PocketShield locks my device whenever it powers on and I can't find a way to cancel that without completely turning it off. Any ideas here?

Prox sensors come in different types. They aren't all configured to turn off "when covered" by just anything. Since the primary purpose is to save screen power when held against your face, it may well be technically designed to detect things that can conduct electricity, like you. If you're curious about it, as I am, next time you test it, cover the prox sensor with your thumb.
If that doesn't work, I recommend on second test. Just because there is a prox sensor doesn't mean that HTC is using only that for turning off the screen. In order to avoid accidentally turning it off while you're trying to use it, which would be annoying, they might be using the accelerometer to detect whether it's being held like a phone or not, and not turning it off if it isn't. Test two is to hold it in a position at an angle as if you would if you were talking on it, and hold your thumb over the prox sensor.
I don't have my TP2 yet, that's why I haven't tried it myself. If you're already on to your current solution and don't want to I understand, but if you do, I'd be curious as to your results.

Tested that with some objects and with my hand. Same results. Even with the phone being held vertically like I'm talking with it, the screen won't turn off if it was covered before the call. When removing the hand/object from the proximity sensor and covering it again - the screen turns off immediately.
Maybe this is not a limitation of the sensor but a simple programmed behavior. If so, perhaps it can be patched... <evil grin>
Update. Under HKEY_LOCAL_MACHINE\Software\HTC\Proximity there are 3 keys: ProximityDetectStatus, ProximitySensorOn, UnexpectedWakeup.
The first key is updated live by whatever the sensor detects. I now know for sure that the sensor continously knows if there's something on top - the dialer behavior is programmed.
I'm not sure what the other keys do. ProximitySensorOn was set to 0 on my registry and now when it's 1 I see no difference. Gotta go, will continue with that later.
Switching the Proximity Sensor off...?!

Although I was looking for other reasons -- see below -- I get the same result; & even when you do change ProximitySensorOn to 1, it doesn't survive a soft reset: simply reverting to 0....
What I was looking for was some way of disabling the Proximity Sensor (PS) altogether: because (i) I'm deaf, & I therefore Bluetooth all calls directly to my 'hearing instruments'; & (ii) I've just bought a case which covers the darned thing (meaning the PS) up, permanently locking the touch-screen when it's on! (Aargh.)
Having spent the last couple of hours (plus) searching the TP2 forums on here (& a related one on PPC Geeks...), I've discovered that: (i) lots of people are having PS-related problems; (ii) some of these problems are to do with TouchFLO 3D; (iii) some may be related to various forms of screen-locking; (iv) some may even be caused by other tweaks or hacks we've carried out; & -- last, but not least, as lots of other proud TP2 owners have bought similar cases -- (v) I appear to be the only one having this particular problem (...probably caused by (iv)?)!
It's as if my particular sensor thinks my ear is permanently glued to the screen... -- I can operate all the buttons & the keyboard; but the screen (even though I can turn it on with the power switch) just will not respond while the case is attached (& therefore covering the sensor...).
If anyone has any ideas -- apart from drilling a hole in the case, somewhere (randomly) to the left of the HTC logo... -- please let me know!
Thank you for reading...

PS: I have a UK-spec., unbranded, GSM Touch Pro2 (...not that this seems to make any difference); & I've already tried turning off any locks & PINs (& changing their duration), as well as the owner information screen....

What is this CAB doing? Because I am also interested in adding support by the Proximity Sensor in TouchLockPro. So how can I start programmatically the proximity sensor? Just changing a registry key

[Q] Disable proximity sensor/Button to wake up screen

Hey guys.
I have a desire which has been dropped and the screen in the top left corner cracked. The proximity sensor is damaged, and I can test with various apps that this is indeed broken.
Now, when I get or make a call, the screen turns off, but since the proximity sensor isn't working, it's not turning on again when I move the phone away from my ear. So I wanted to know if anyone knew of a way of either completely disabling the feature, or a way of manually "waking" the screen again, by using any of the hard-buttons?
Thanks
what happens.. when you press power button
Sometimes it comes on, but mostly it doesn't... Regardless of which button I press...
I have read somwhere.. that by blowing some air over that part.. may clear any blocakge.. and proximity sensor works fine.. just try this .. use any vaccume cleaner.. and blow some air over sensor part..
And if that doesnt work.. search for this app in market "'Proximity Screen Off' ".. it might help you.
Yeah, I read that too... Tried blowing with compressed air even. The sensor is dead :/
Try this app.. it will switch your proximity sesor off after call ended.. its not mine just found. you might wanna try this

Hy, i have got the same problem !

[Q] Phone call disconnects when open screen ??

Hi;
While on a call, the screen will close. While still talking I press the side button to open the screen and the call will disconnect.
How do I correct this?
Thank you.
Same question. Its just stupid, how on earth I`m supposed to wake up screen without disconnecting a call ?!
Go to: settings>Accessibility>un-check-power button ends call
what's funny is i'm pretty sure that this setting is not selected out of the box, so you guys must have went and enabled it yourselves!

I don't know about yours but my SGN seems to have proximity sensor near the speaker and it seems to turn screen on as soon as I take it away from my ear auto-magically It may "lag", but it's fair enough for me...
Mine did the same thing today. I confirmed the accessibility link cited above was not checked. Proximity sensor is irrelevant, I was on a two hour conference call and speaker using speaker phone mode. Screen times out and shuts down on its own, which also shuts off the prox sensor.

dark screen when have phone call

Hi guys
Since one day , my screen turns dark when having phone call or receiving phone call.
I can't type the keyboard and press the speaker button, which are inconvenient.
I have updated fw to fw_capricorn_miui_MI5S_V9.6.1.0.NAGCNFD_857fde8b41_7.0.zip
I have this issue on different roms including lineage 14 , lineage15, RR,and pixel experience .
Do anyone also have the issue and do anyone know how to solve it.?
My phone drop to ground once which cause screen crack. I am not sure whether this is the root cause.
Many thanks
The phone has on the front a proximity sensor, which is basically a small light sensor that checks if the phone is near the head or not. If it's near the head, it turns the screen of, so that you don't press any buttons while holding the phone to your ear.
I think either your sensor is broken or the crack always brings light to the sensor.

Could I disable this function?
Always disable light sensor or disable when have phone call
I had the same problem I thought the sensor was broken (you can test it with sensors test https://play.google.com/store/apps/details?id=asd.vector.sensor ). But it was ok, it turns out it was firmware related. When I downgraded my firmware the proximity sensor was working again...
Good Luck

Is anyone facing an issue with the proximity sensor in OnePlus7T

Ever since I've bought OnePlus 7T, the proximity sensor is giving me a lot of problems. Sometimes the screen lights up while I'm speaking on the phone and the speaker is activated. Sometimes the call gets recorded. Sometimes if the phone is in my pocket and I try to unlock it, it says too many attempts.
Yes it very annoying, when removing it from pocket accidently my fingerprint matches and something something happens.

Yes I too have this issue with my OP7T
Yup, same issue here.
Another thread about it here - https://forums.oneplus.com/threads/proximity-sensor-doesnt-work.1147600/
Also issue present on OP7Pro forums.
Seems to be related to this "Virtual Sensor":
https://www.ellipticlabs.com/2019/0...eaner-design-to-oneplus-7-series-smartphones/
So we have to wait and hope (could be this same as Never Settle? :d) that can be fixed with a software update.

Someone on the OP7T forum suggested it may be Tap the Screen to Show (let's call it TSS) feature.
I enabled DTW. This will trigger Ambient Display -> "Tap the Screen to Show" to be disabled.
Tried and the screen still won't turn off when on a call with the phone on my ear.
Both options disabled (no DTW and no TSS), still won't turn off.
What did work though, was to turn off screen once with the power button:
- I was in a call and the screen was on,
- turned off the screen using power button,
- I took the phone off my ear -> Screen on
- put the phone back on my ear -> Screen off
Maybe someone can make more sense of it.

I tried the above also same thing. I am tired of this BS. I am constantly pressing hold or dialing with my face unless I have the phone shoved in my ear. I almost didn't buy the 7t cause of this issue coming from the 6t with the same issue

Yeah, I am starting to remember good ol' days with the OPX. Every OTA was fixing one thing and breaking 3 other.
At that time I said no OP again, but still, this one seems to be be a good phone. Time will tell.
Coming back to our issue, I am puzzled that only a few people reported this.
Are you guys are on stock kernel or something custom?
I don't think I have this issue, but the sensor seems to function a bit differently from what I'm used to. When the phone is horizontal, covering the sensor does not turn off the display. But now do the motion of raising the phone to one's ear, and the display turns off. Just an observation, yet to experiment properly.
Does anyone know where the sensors are located on this phone? Is there a picture on the internet that points out the different sensors?
Edit: Yep. This one has a virtual sensor. It works differently.

Not rooted, but using a custom dialer as the default Phone app (True Phone).
When I switched the default Phone app to Oneplus App, I could not reproduce the issue.
Testing for a few days to see if this works. Would be such a pity if the app is the problem because I really like it.
Also I just sent a log to OP support (they contacted me after I logged the issue on the feedback).
Yes, it is using the virtual sensor as you said (link in my previous post).
How does the virtual sensor work?
Sent from my [device_name] using XDA-Developers Legacy app
I couldn't find anything concrete on how this software-based proximity sensor, Elliptic Labs INNER BEAUTY, works. The keywords are: ultrasound, sensor fusion, and machine learning. A hardware-software I guess.
The 7T does have an IR sensor under the display, but I think this is only used for DT2W and Tap to Show to prevent the display from accidentally turning on when the phone is in the pocket and so on. Not for calls.
Fully Unmodified phone - same issue here. Phone regularly turns on airplane mode while I’m on a call cause it is registering face touches. Screen regularly flickers while on calls as if rapidly moving away from my face....
This was not a problem on my 3t a while ago and the issue is driving me to switch phones alongside some software instability (random lag and keyboard jitter) (animation issues after launcher swap) (soft-lock on navbar or gestures but not a play store replacement)I usually fix by rom swapping on one plus phones andddddd twrp is dead (for now) and no ones working on a valid replacement.
Will be keeping this phone in hopes of twrp eventual return, but need that stability

Twrp is out for the 7t. It's not flashable last I checked but it is bootable and usable for what I used it for which was a backup of stock rom
