Proximity sensor issues?

I'm running CM 7.0.3, and I'm having massive proximity sensor issues, t the point where the phone is becoming unusable. If I'm in a call and I don't manually shut the screen off, the following happens (constantly):
I'll feel some haptic feedback on my ear, and my voice will mute. When I look at the screen, the lock screen is up and when I unlock it, it's at the dialer screen. I'm not hitting the mute or hold button with my ear, it seems like once it gets away from the call screen, my voice is muted.
Needless to say, this is getting massively annoying. Later tonight I'm going to try to see if using a Sense based rom fixes this, but I'd much rather stick with CM. Has anyone else experienced this?

I believe there is another post on this.. you can also Google search for inspire proximity sensor adjustment - someone created an app to adjust the sensor

The thread in question:
http://forum.xda-developers.com/showthread.php?t=1062561
EDIT: I haven't used the proximity sensor adjustment application that's linked in the thread as mine is working normally. If it doesn't work there's a possibility the sensor's faulty and should be replaced (I recently went through this whole thing with my old iphone 4).

Yeah, to be honest, I tried that app and it didn't seem to make much difference. I'll try calling HTC

Flashed to a sense based ROM, and the sensor seems to be working fine. Very odd, to be honest. I will say that after using AOSP for so long, I have no idea how you guys deal with Sense at all.
Well, now I have to decide: I can live with Sense, or I can ship my phone back to HTC and be without a device for 2 weeks. Going to try out the proximity sensor app again, but it didn't seem like any setting made a difference, but it could be that I just don't know what I'm doing with it.

Check under Settings>Call Settings and put a check mark in the "Always use proximity" box. It says it's to help with prox. sensor screen locking when the phone is horizontal, but the CM7-based ROM that I was using showed the same issues and I fixed my particular issue by checking that box.
Tested with a few calls and the screen is definitely shutting off when the phone is standing or lying down.

I read up on the proximity app, and I think I have it calibrated properly at 5/6. It certainly helps, but it's definitely not perfect. Night, thanks for the advice, but yeah, that option has been checked from the start. At least the issue is tolerable now, before it would do this 10 times per call.

Funny - mine was calibrated at 10/11 by default and works pretty well. Try going up to those values. I used a local time/temperature number here, and it worked well when my finger got 1/8" or so from the phone. While I admittedly haven't measured the depth of my ear or anything, it does seem to be working well at those settings.
I think the upper threshold is where you may want to adjust. From my playing with that app, changing the lower threshold too high will make it ignore things too close to the phone and so will an upper threshold that is too low. Try lower 5, upper 11 and see what happens. Anything between lower and upper apparently triggers the sensor. (<<< speculation without documentation)

Touch screen sensitivity

Hello. I have an Nvidia Shield tablet k1 on lollipop 5.1.1. Everything is great about this tablet except the touch screen. It is really sensitive. Also, when I am scrolling, it "jumps" and goes faster than I actually scrolled. It scrolls faster than it should. I found this thread on xda. It helped a little with the being too sensitive issue, but scrolling is still really weird. This is my second device since the first one's micro sd card was defective. They both are like this. Is there anything I can do, or do I just have to deal with it?
http://forum.xda-developers.com/shield-tablet/general/adjust-touchscreen-sensitivity-t2963326

I was opening a thread with this exact same issue. I'm not on stock though (using the latest CM12 nightly), so I don't seem to have the 'Sensor Calibration' option.
Also the touchscreen seems to register a touch even when the finger is not touching the screen.
On the other hand, if I scroll a very small distance (like 0.5 centimetres) the list I'm scrolling doesn't move at all. This doesn't happen on other devices such as my Nexus 5 and Nexus 7 and is very annoying in some cases (some games, or moving the cursor for keyboard input).
I'll try to record a video of this behaviour.
What can we do to fix this?
Update: found a video (not mine) showing the issue I'm talking about: https://www.youtube.com/watch?v=08uPtusOJHQ

anyone else with this issue?

I also have this issue on/off sporadically on stock rom.
I'll be scrolling and itll jump back the opposite direction
Its like it looses track of the touch then catches it again.
It's irritating as my S5, Nexus 2012 have no problems scrolling smoothly.
I don't recall the original shield i tested in store to have this issue either.
Currently having amazon ship me a replacement to see if its just limited to the one I received. (QA issues)

Calibrating screen might fix the issues: go to About in settings and tap on model number until the calibration screen comes up. then hit calibrate. don't touch the screen then when it asks to reboot, reboot.

Did it fix the issue I posted the video about? I'm on Cyanogenmod now so I don't have the option to calibrate the screen, but I would consider going back to stock if it fixed this issue...

Calibration doesnt help at all , same issue at brand new k1. Nvidia says thats normal functionality lol

Yeah, very normal for a gaming tablet which would require precision...

Not trying to take up for this thing but I haven't had the first touch screen issue with it . so maybe not all is affected?? I've tried to replicate the issue but just can't everywhere I touch and slide is smooth

You mean it doesn't "jump" like the OP said? I don't seem to have that issue either.
I'm more concerned about the touchscreen's precision, as shown in the video.

ghost/phantom touch issue in 1+7pro not solved

I have reading the forum and tried contacting 1+7 also but they just say switch off nfc and so on but till today (1 month since I bought it ) I still have the problem . while making a call it goes on hold or connects another call or something or the other happens and the other person gets irritated as if I am doing on purpose. I am still unable to solve this will changing rom be the solution or can someone please help I am fed up with this instrument

My 2 cents... are you sure that it's a ghost touch issue? To me it seems more a proximity sensor trouble... it is possible that, while in call, screen doesn't go off (or wake up while you're talking) and your ear triggers commands at random.
Try to check that your screen remains black while in call, else you could try to reset sensors with one of the apps available on Play Store.
BTW: I had a similar problem one or two times, but maybe because I wasn't so near the phone while I was talking.

will try out can you advice reset sensors apps

Search for "Proximity sensor reset" or similar names. Usually apps like that needs root privileges, btw.

I've had problems with the screen waking up and then causing problems while in call too. This while it's still against my face. Apparently touching my face makes it go into other apps and causes problems. I've had it go into airplane mode, mute and do other weird stuff.
I've had the screen go crazy with multiple chains of taps too, especially while holding it in landscape mode.
Turning the refresh rate down to 60 Hz helped some, but the problem's still there.
I think there's something jacked in their implementation. I came from an S8 that had a curved screen and I never had the phantom tap problems I have with this thing.

Disabling double tap to wake resolved my screen wakeup during calls issue...

UPG to 9.5.10 Plz - Issue has disappeared again.

I'll try that, but I don't think I have that enabled. I disabled NFC for the other tap issues and that helped some.
I really wish there was a screen calibration tool. Samsung curved screens have none of these issues.

Do you have a dirty screen protector?

This is a known bug with the proximity sensor, although, actually, I believe the root cause is something else.
Screen does go black, which indicates the proximity sensor is working and recognizes your face is near... But input is still allowed (meaning it does not lock it).
As a result, during a call your face/ear will press whatever is underneath and trigger random actions.
I believe (I hope?) that OnePlus is aware of this issue and they issue a fix.
I think it was briefly fixed for 9.5.9 and then reverted on 9.5.10 since it introduced other issues.
Quality control has been a bit subpar on the OnePlus 7 Pro builds when compared to my previous OnePlus phones...

Question Some times touch is missing over the fingerprint sensor area

Hi everyone,
It's 2nd day of using my S22 ultra snapdragon version,
I noticed sometimes touch doesn't work over the fingerprint sensor area for a few seconds and after a while it works fine. Most of the time I noticed while typing on the keyboard, T & Y keys at the sensor area these keys are often missed while typing.
A comma placed left side of the space bar and it presses automatically while typing.

Try clearing the system cache.
May be a hardware issue if so it's not going away. Test it.
The variable refresh rate displays have been suffering a higher failure rate across the board.

Lot of reports of ghost touch on Reddit when typing. Happens to me too, hopefully it'll be fixed in an update.

It's not not the refresh rate setting issue but rather the hardware and/or firmware itself.
In Accessibility settings your could try playing with the touch and hold delay setting. I would also test the display for touch dead spots as well. Your problem may be different from what others are complaining about.
On a returnable phone I wouldn't play with it too much as that's an obvious flaw.

rescan the same finger as 2nd fingerprint

No solution in accessibility.
I already scanned more than one fingerprints.

Found a solution for ghost touches.
Turn off the Touch sensitivity.

Question Bug with proximity sensor

Hi guys,
It often happens to me that screens shuts off when I try to click on top tier of screen, it's really annoying especially with full screen apps.
I recently put on screen protector film but I don't know if it's due to this.
Anyone has this problem ?
Many thanks.

Are you rooted and using [MOD][Xposed+Magisk][Pre-Release] AOSP Mods - System modifications for AOSP-based Android 12+'s option to double-tap the status bar to sleep? If so, it might be related to that setting. I was trying to reproduce a different bug, playing a full-screen landscape YouTube video and I found almost every time I tried to make the status bar appear and then drag it down, I accidentally shut the screen off.
Luckily for me, I rarely try to do something like that while in a full-screen landscape app, so I'm keeping that setting on.
If you're not rooted or not using that Magisk Module, then ignore this.

I'm not.
It happens even whith WhatsApp when I select a message in a conversation and try to click on delete icon located in top screen, screen shuts off.
Where is the promixity sensor ?

I'm not really sure. I just unlocked my P7P and ran my finger across the status bar, back and forth and I never found it.

Meanwhile, the cutout for the proximity sensor has been slightly tweaked again and is more to the right of the front-facing camera than last year’s Pro phone.

I have the same problem. TMobile Visual Voicemail has its delete button just below and to the right of the front camera and the screen turns off before I can delete the playing voicemail. I have to go back to the full list of voicemails and delete from there.
