Hi all, I have a weird problem with the proximity sensor in my HTC Titan. I got a new Titan about a week ago, to which I immediately installed HSPL and Dynamics rom. After I did all the tweaks and installs I like, I noticed that every time I dial a phone call the screen goes off and stays that way until the number I called answers. If the number does not pick up, only thing I can do is remove the battery basically to hang the call up. I noticed that removing the back cover slightly affects the issue and its easier to get the screen back on (by pressing the power button), but still removing it does not solve the problem. With a handsfree I can actually stop the call as it has an accessible end call button.
I tried flashing another custom rom and also a stock rom, both had the same issue. So, I took the device for warranty repair. I got it back today from HTC, with a note saying that software has been updated and problem has been fixed. I tried the device and surely it was working. Well I can’t live without an fully unlocked device and against my better judgment flashed a custom rom again… And surprise surprice the problem appeared back.
Im thinking here that could I adjust the proximity sensor from the registry, if its somehow too sensitive or something. Strange part naturally is that other people with same rom are not experiencing this behavior, so it is device specific problem. Also I don’t think I can take the device back again and say yeah I was flashing some custom roms on it and lost whatever you did with it.
There a Proximity folder at HKLM and I tried changing some values there but no affect at all. It probably would be better to have someone who understands about the values little try to take a look.
Thanks a lot!
It's a hardware problem. I got the same issue after 2 months of use. I sent to repair but they wanted to charge me to do that, so I haven't fixed it but I still can get the screen back by pressing and rubbing my finger on top of the sensor.
But when I got it back from repair today it was working. I made few phone calls and it was working totally like normal.
you are not alone

I can tell you that you are not the only one with this problem, it happened the same to me. I'm still unsure if the problem is hardware or software, but I think it's software because it happened just after I install Dynamics_2.0_Titan. I really wish that someone will bring a good solution for it.
It is normal for display to go blank due to proximity censor while making calls. In my case however,occasionally the display stays blank even after the call gets over. This also happens every now and then when I lock the phone, only to never unlock. At times, the displays backlit switches while unlocking but not all the time. The phone's processor stays awake in both the cases (calling/locking) and the phone rings & vibrates perfectly on making calls. The only option that I have in such cases is to restart the phone. Is anyone facing similar problems with their phones? I've done a factory reset off late but still the problem persists.
Are you using a screen protector? May be you haven't aligned it properly and hence proximity sensor detects it and turns off the display??
I've had similar situations happen to mine, but I figured out that after a Skype call on my phone, the proximity sensor will remain active and will sleep the screen if something's covering it. I'm not sure if you have skype running, but if you do, that might be why.

I don't think obstruction of the proximity sensor is an issue since this problems occurs even when I lock and then try to unlock the phone. Also the backlit turns on at times when I try to unlock the phone.

Well, what you're facing right now is a classic example of what people face when they keep on the protective covering used on a new phone when the phone is shipped.
If you think it's not the issue then search for any apps which you might have installed? Run the phone is safe mode and see if it acts up? Flash stock images or do a reset to rule out the possibility of a software issue.

After few days of working flawlessly, today again the display blanked out while it was locked in normal mode. I tried unlocking the phone but only the backlit would light up. So I restarted the phone, activated the safe mode as suggested by you and then few minutes later, again the display blanked out. What should be the next step now? Please elaborate on flashing stock image. I've earlier done a factory reset but I immediately installed all the apps.

Well, if you're facing the issue in safe mode as well, any apps might not be causing it. To flash factory images, you will need to unlock the bootloader. Follow the guide which is linked in my signature.
Since you don't know about how to flash stock images, I assume you haven't rooted and undervolted? Display black outs while unlocking the device can be caused due to undervolting as well.
It could be a hardware problem on the phone I had before the n5 with my lg g2

Possible, but he should exhaust all software options before seeking out a replacement.

Hi,
I got my new Onelus 6 five days ago, and i installed the latest updates (ONEPLUS A6003_22_180614).
For the last three days, i've had issues with the screen going black. When i lock it and then try to unlock it, the screen doesn't switch back on, it keeps being dark.
I tried to reboot it several times (Volume button + power) but the screen is still black. The phones vibrates and the LED works but the screen doesn't.
I tried to remove the SIM card, but the problem is still here.
Sometimes after 100 trials, the reboot works, but the problem comes back as soon as i try to unlock it.
Do you know where this bug might come from ? Firmware problem or phone problem ?
I really don't know what to do... I hope you'll be able to help me !
Thank you
Sounds like you should contact OnePlus and it may be a defective phone. Maybe have to RMA it and have it replaced.

Have you tried a factory reset,or using the msmdownloadtool
My phone is brand new, I don't think a factory reset would change anything, does it ?
I want to see what OnePlus support can do for me before trying anything with softwares on my phone ! (I don't want to loose warranty)

I had a similar issue within a day of getting the phone. Nothing worked and had to send for replacement.
Try to reset to the factory settings. If this can't help you, refer to the service center or to shop where you bought the phone.
Hello. I'm having the same problem. Bought my phone couple days ago and it runs ONEPLUS A6003_22_180713. Don't know what to do sinse there is no OnePlus service centre in my city. Have your problem been solved? Have you done anything special?
Hi,
Unfortunately I had to send it back to the website where i bought it. I have been refunded, and i bought a galaxy S9+ (cheaper than the OnePlus 6 i got)
Even i got the same issue since Pie update.
Had rooted when it was on Oreo, when Pie (OOS 9.0) update came, it came with a new issue. Whenever I unlocked the phone, the screen would flash with blue lines and black background multiple times then show the lockscreen. And now with OOS 9.0.2 the issue went even more drastic, the screen kept on flashing while using apps. Even forced reboot didn't solve the problem. I had to power it off and leave it aside in nighttime. The issue has decreased but the lockscreen flashing still exists.
Temporary fix - https://thedroidguy.com/2018/07/how-to-fix-oneplus-6-that-wont-turn-on-easy-fix-1087099
If the issue increases, then I would restore Oreo ROM and relock the bootloader.
I need help tooo!

Best solution is to keep the screen ON always. Or else that flashing bug will keep recurring.
But this is a temporary fix and not all would like to keep it Always ON
Same here from 3 days ago. OX 9.0.2
The phone hangs, No respond and must hard-restart the thing.
Same issue here,since the past 2 weeks.The phone screen keeps flashing when the phone is locked and even restarting the thing 20 times doesn't make the phone start.The LEDs work fine,the phone receives calls and messages too but the entire screen is black and unresponsive at the moment I face this issue.The moment I lock the phone the issue crops up and it's a pain to restart it every time it happens.
Hi
Just got my U12+ today. I've noticed that quite often if I unlock the phone by fingerprint, it shows the home screen but the screen is totally unresponsive. I can't click/touch anything.
It remains unresponsive, even if the screen times out (1min later) and then I reunlock.
The only way to fix it is to use the power button to switch off the screen and then it will work immediately afterwards when I unlock.
I have done multiple restarts, and 1 hard reset and it is still happening.
Any thoughts on what is causing/how to fix?
UPDATE:
I've spent quite a few hours googling and testing different setting options, and the issue seems to only occur when "Smart Display" is turned on.
If the Smart Display is on (either motion or always on) gets engaged, if I then unlock via Fingerprint, it shows the home screen, but the touch screen is totally unresponsive. It doesn't register any taps/touches (I turned on Dev options).
Is this a hardware or software issue? Anyone else experience this?
Thanks

Phone model and current software build.
Are you rooted? Any root based mods, kernel, room, etc.
Hi
Thanks
U12+ running 1.21.454.3
Totally stock. Only got the phone on Saturday.
Did one hard reset and issue still there.
In usage since my last update, it is 100% related to the Smart Display. Absolutely no issues when it is turned off. When I enable Smart Display, then it starts freezing again on unlock.
Hi,
I'm having the same problem too..
I got my set on the 15/09/18, Hong Kong Set.
Mine is currently on 1.25.708.3. But prior to the update, I am already having the same problem described by leginag.
I even tried to do a factory reset but the problem still surface. It will become unresponsive after waking up after a period of screen off (not sure how many minutes).
After turning off Smart Display ( thanks leginag!) , I'm able to use it flawlessly. I was about to unlock the bootloader and flash a custom rom though..
I think this problem is quite disruptive, especially when a call comes in, or when launching the camera app through the edge sense. I can only snap using the squeeze.
Nonetheless, I hope there are other alternatives to Smart Display though..
Hi, I've been having the same issue. Thanks for looking into it hopefully it gets fixed in the next update.

I hope it does get fixed. I reported it to HTC and they said they would forward it to their engineers. That was 2+ weeks ago, and nothing else heard back.
Best thing for you to do may be to submit a support ticket to HTC. If everyone who has the issues sends it in, this will flag it with their engineers that it is a wider problem.
Could you let us know your model/firmware?

I have contacted HTC and am awaiting a reply. My current software version is 1.25.708.3
Thanks.
Hoping this issue is software related. So far, only people with Asia models have reported it (only 3, but at least I'm not going crazy by myself!)
ASIA HK - x2
ASIA JP - x1
Got a response from HTC, saying it is a software issue and should be fixed in next update - around mid-October.
Today, I got information about that this issue will be solve by software update.
Moreover, it is arranged on around middle of October.

Thank you for this. I just got my u12+ and thought it was faulty.
Turned off smart display.
I'm having this problem as well, Asia HK.
Curious, is anyone also having problems with TWRP? I almost always get a nonresponsive screen when fastboot booting.
Just a heads up that the 1.30 update has fixed the issue for me.
Which is a relief. Not that I was missing using Smart Display, but just feel better not having an issues with my phone
Hi there,
I am using Asia HK and have the same problem with you.
But I still didnt receive any update patch for 1.30. May I ask which area did your phone belong to?

I've had this issue twice, once on 1.25 and once on 1.30 so I do not think it is fixed yet but it has been very rare for me. Only twice since the phone launched but it is very inconvenient when it happens. I could only fix mine with a reboot.
Removing my original reply as I don't believe it relates to this bug after all!
(A Factory Reset sorted out my device, incidentally)
Every time I unlock my screen, whether it's with the fingerprint or pattern, the screen will flicker for half a second. Super annoying because it's a bright white flash.
It's not face unlock assistive lighting, as I've ensured that is turned off.
I've also tried every display setting possible, toggling things like vision comfort, comfort tone, refresh rates, display calibrations, changing wallpaper, and so on.
Really hoping this isn't a hardware issue because I'm also noticing my touches don't register all the time, unless I'm pressing the screen slightly harder. Not sure if it's my screen protector but I am left a bit concerned.
Any ideas? I've Googled this a bit and I've noticed others have the same issue but on OnePlus 6 devices for the most part, not the 9 series. If anyone has run into this before and knows a fix, I'd love to hear it, thanks!
That's how the fingerprint works. It increases the screen brightness to the max usually. It's the flaw of using that kind of fingerprint rather than sonic like Samsung. Believe it takes a picture of your fingerprint and compares vs ultrasonic gets a 3D image, the difference is in speed too, optical is faster, but ultrasonic technically more secure and does not rely on lightning conditions. I personally prefer the hardware on the back kind over both.

I don't remember it being this prominent on my previous OnePlus devices, though. My 8 Pro did not flicker as aggressively as this one does. It's enough for me to clearly notice it, even in brighter areas; this is why I've been left with a bit more concern than usual.
Not to mention this occurs even if I use my pattern to unlock.
Not sure. Mine does the same but doesn't bother me in the least bit. If it happened at other times other than unlock would be different story.

Any chance you could try and make a video of it happening on your device? I just want to see if it's the same thing as mine. That way, I'll have a better idea of this being a defect or normal behaviour.
I know, it's kind a big ask so no rush! If you ever have time. I can do the same if anyone needs to see what I am talking about exactly.
Update:
I've noticed the issue occurs only if the lock screen is showing. If ambient display is on and the fingerprint icon shows at the bottom then the device will unlock without flickering. The fact that it's happening only when the screen is on at the lock screen, is what's making me feel like maybe it's not a hardware problem. Very odd issue...
Another update,
After doing more Googling I came to the conclusion that it's a hardware issue over software. I tried to factory reset and the issue was still present.
I couldn't update the software on the phone though. It kept telling me that there was an installation problem. I'm guessing that's because I had previously used a rooted EU boot img and a factory reset through the phone settings isn't enough to get rid of that. I'm hoping the repair center won't fault me for sending the device back with an unlocked bootloader. Doesn't seem like OnePlus would do that anyway, given how open they are with the modding community.
Once I receive the replacement of test to see if the issue was still there and will update this thread.

One time I sent them bricked device and they still accepted the return. Returning unlocked bootloader phone shouldn't be a problem.
What made you think it was hardware since I see other people have the same thing. Hell I had it too. I don't seem to have that problem after updating to latest firmware. Seems to be software to me.
Hope it gets fixed. I saw a thread for it on OnePlus community forum, so hopefully OnePlus knows.

Thinking it's hardware because my 8 Pro doesn't literally cause a white flash of the entire screen, it would just up the brightness which is normal.
And I was also noticing my touches only registered on more firm presses. Made me think it could have been a bad display panel.
Didn't want to take any chances especially while inside the 15 day return/replacement window.

Yeah good plan.
It absolutely does NOT do that on mine. Only the fingerprint area gets bright, not the entire screen.

+1 on the 9Pro
According to the OnePlus support section of the site, the progress shows as "Inspected". I assume the next step is shipping out a replacement. Hopefully it's soon, will post an update on the new unit.
Thanks for letting me know you guys aren't experiencing the issue, makes me feel good about my decision of sending it back. Almost didn't do it because I didn't want to come back to this Pixel 5 after being spoiled by that 9's screen size lol.
Got the replacement today, after some testing it seems like this unit has no issues! There is a clear difference between this one and my original. There was a blinding white flash even when using my pattern to unlock. Same thing when double tapping the lock screen to put the device to sleep.
This has no white flashes so definitely seems like a hardware issue. Finally, I can start enjoying this thing!

No it happened on any brightness. It was just more noticeable in low brightness and reading through the same issue on OP forums, others were confirming it is hardware related as a complete factory reset isn't able to resolve the issue. If it was software related, a complete restore would have/should have fixed it. Your issue might be different from what I was experiencing.
