Question Screen Flicker During Unlock - OnePlus 9

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.

When I sent the phone away for trade in there was no mention of rooting or bootloader unlock. Just wipe it.of your info and data.

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!

How bro it can be a hardware issue.. it's only happens on low brightness when you unlock the phone right?I am also facing the same issue but it is not there where I unboxed the phone and used it for 1day after receiving update to os 11.2.7.7only this problem starts to me..so how can it be a hardware issue

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.

Digitizer not responsive sometimes

My U11 is having problems recognizing touches. The digitizer itself is fine when I check with testing apps or the developer options. However in normal everyday use, I find myself having to repeat actions quite often, maybe once every 20 touches. It's not really consistent... sometimes it's like the phone expects you to be REALLY precise when tapping a button or text label. In other cases light touches are not recognized until I try a 2nd time. And sometimes I try to open the navigation drawer by swiping from the left edge of the screen and again I have to try a second time.
The phone works perfect if I am really careful when using the screen, but in my previous HTC phones (M8, 10) using the screen was completely effortless so this is a bit odd.
Anyone experiencing something similar?
I've noticed the same thing. thought it was me. I get it sometimes moving icons around and other times. I'll keep track of when and how and report.
I may be able to test with a 2nd unit in a few days, I'll see if I get the same issues.
It does feel like a software calibration issue rather than a hardware one though. I have the "show taps" option enabled in dev tools now and the taps are definitely being registered, it's just that the actions are sometimes not triggered.
Same here. Sometimes have to tap 2 or 3 times.

The same problem here
Odesláno z mého Pixel C pomocí Tapatalk
I have the same problem; most prominent when my hands are too dry, and worst at navigation buttons under the screen. Maybe use the glove mode?
Just updating the thread to say that the phone is now working a lot better. I still get the odd tap that is not recognized but it's not nearly as common as it used to be, the phone is perfectly usable most of the time now.
Not sure what changed, I came from a M8 so maybe it was just a matter of getting used to the new size of the device (the way you type does change quite a bit with these larger screens), or maybe there were improvements in the software, I went from 1.03 to 1.13 a few days ago.
Same issue on 2 household U11
I just got the phone about 2 hours ago. I agree sometimes touches don't register. Very annoying.

Same here as well, thought I was losing my mind. Also I can be typing something and it will trigger the pull down notification tray up top, weird. But it's very inconsistent. I don't recall seeing this before the latest update.
Sent from my SM-G955U using XDA-Developers Legacy app
Same for me, hopefully some update will fix it.
I don't think an update will fix this. The issue was so bad I asked for a replacement. Unfortunately, it will take over week to get a replacement. HTC Customer Service takes forever to respond, then shipping phone back, and then getting replacement.

Well I don't think a replacement will fix it either then.
My second unit has the same problem so I would say replacement is not a solution. I hope they can fix it by some SW update.
Same problem here. I just did a factory reset last night to fix a different issue though so I'll see if it's still happening.
Have also touch issues and will now repair this from HTC.

SOD (sleep of death)

I noticed, that my 1+1 always works ok on stock roms (cm11,cm13 from this forum) and when i set up Android Oreo or Halogen (7.1.2 unoff) or even Flyme 6, my screen don't want to wake up from time to time, buttons vibrate, sound works, all works except screen. Even though, i noticed one way to wake it up, just repeat the touches some times, double tap to panel (i don't see it), and again, to block the screen... it wake up always, or reboot sometimes, but this is not a variant to use at real situations. somtimes headphones help, sometimes usb cable, but no 100% solution.
may be someone know how to solve this problem? i saw a lot of messages here about SOD, and no solution. just something about a modem or flash stock, but this is a software trouble, may be it is firmware.zip or just one .bin file inside (power management). may be this error can be solved?
I really want to go to Oreo and today i tried to do it, but when I suddenly understood that it doesn't work again (after stock) i decided to go back, no way to use it. may be i should take some files from stock?

that's the way, but not for me. i've just changed my display, i just can check old one, it is not broken, just a dead zone on the touchscreen. but it means that the revision is incorrect, it is something like a driver, i think. i already had the same situation with a old tablet, it didn't wake up anytime after boot, it was discussed at 4pda, so people found, that only one of the 3 revisions works ok at last firmware, i had 2 type of display and could to swith and check it. but it wasn't so good with colors, so i stayed at stock. it seems that situation is the same now.

Why do yoy think so? Stock fw can realize all functions for that display, why custom can't do it at the hardware level? no reason to think so.
Just only one idea - is a revision. Now i can try my old display. And if i'd manage to change touchscreen, that can be a solution. But i don't.

Aliexpress?
Yes. But at first everything was ok. And when i installed oreo it stops some times and Sod started. I tried to use 7.1.2, it SOD's anyway. Then the stock was the solution. I'm already relaxed, and decided that it is software error, but after a few days it started again.
I've accepted this display, but with your help it's not so late to open a dispute. I think it will be ok.

See previous page,I've already explained what is the cause of the issue.
I just finished replacing my screen, been waiting for my broken antenna cable and volume button flex to arrive. Everything works except the damn SOD i never had with my old screen. Tried turning off the proximity sensor check and still a no go. The screen turns on fine initially and trying to wake it instantly works all the time, but if I leave it off for any longer than 5 sec probably it won't respond to anything - power button, volume button, double tap and plugging in the usb cable connected to a power source.
Does this sound more like a governor issue? The rom installed is lineageOS (just updated to 10-30 release). Looking up my purchase log to open a dispute...
tested it again, repeated lock/unlocks puts it into the SOD state, doesn't even take 2 sec to do it...
oh wow, it does this even in the twrp recovery. I have wiped cache and dalvik cache just for the hell of it but doubt that was the real cause...

i've got the first SOD in twrp mode. it doesn't matter, but at first - no troubles were with that. and now it works so so at home. and if i use it outdoor it becomes very often, but at home it seems that it works ok, just only seems, because if i want - i can do some manipulations (use camera, lock/unlock it etc) and the SOD appears again. but custom os executes SOD more frequently. i think it can be real overvoltage, like people says.
there are many posts here and everyone advices not effective solutions (flash stock, modem, fw ...) at first it helped me, but now i know there is no way, i can just try but ...
long time ago i owned an old tablet iconbit matrix - it has just the similar issue. it boots, but if you go to a sleep mode - it didn't wake up every time. it lights works ok inside, but no image. i had two displays and if i used one in a custom rom it worked ok, but not another one. stock rom works ok with every display. the solution was a display driver, like at windows OS.
cause of developers bugs, it was a little different (not stock-based) and some revisions of display works ok, others aren't.
so, i think it can be fixed, but the solution for me - change a display like the first reply says. Ali seller read this topic and posted me this in a few days after i started this topic:
Your dispute has been processed and the money will back to you in 7~10 working days.
so could you give us a positive feedback, please?

They always ask for positive feedback in exchange for refund/replacement.Bastards,aren't they? @evronetwork
For the sake of other people that'll read your feedback and make their decisions upon it,don't do it! Just complain this bribery to aliexpress staff ffs!
well I wish I bought from aliepxress... I bought mine from ebay to pinch some pennies, and because I was waiting on other replacement parts (which were only needed due to damage occurred during a screen replacement op) to ge here I am way over the protection period. aw shiiiiit, I guess you live and learn
gotta tell you though, the screen is a bit wacky in other ways too. the capacitive buttons do light up but not completely (kinda dark in the corners) and the colors look a bit off. hopefully the seller would honor the refund/return request...
EDIT: whoa... kinda hard to believe, but I messed around with battery profile just for the hell of it and by some pure luck discovered that the "performance" profile (second one from the far right) works just fine and wakes the screen every time. The "balanced" profile and everything below that gives me an insta-death. go figure!
EDIT2: guess I spoke too soon. it sure as hell looked like fixed, but it came back after a while. maybe it is just more sporadic than I thought...
No solution yet? I think, that it can be some trouble with lights (this wire with 3 contacts), because touch starts, but no image. may be the signal comes to the matrix, but it is not enough energy to enable this diods. what can we do? im going to change the back side of the screen.
ow, no way, don't even try, it has combined technology. i disasabled the whole wire, no chance there...

What happened to getting a new display?
I use this one, because it works ok, but only at home. As a home tablet. At the street it fails every time.
I can reboot it if it doesn't wake up. But it wakes up often, so i don't want to order new one now. I want to check my mainboard to be sure, that it is dispaly problem
a bit late, but thought I should update on the situation... all working fine after a (yet another) LCD replacement. Much better color balance to boot, points to QC problems at the supplier's end. If I ever have to do this again, I am definitely going to inspect the new LCD as soon as I receive I receive it.

Screen non-responsive when using Smart Display - Hardware or Software Issue?

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?

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.

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?

Asia TW and Asia JP have already received the 1.30 update (I had to manually check for it though). Hopefully HK will be soon!

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)

Pixel 3 screen flash

Didn't see this posted here yet, but forgive me if I missed it.
Trying to find out if anyone has seen or heard of any acknowledgement from Google regarding this. My new Pixel 3 (Verizon; non XL) since day 1 has had an annoying issue with the screen flashing when ambient screen engages. I have my settings with alwayson set to off, and new notifications set to on. If the screen is asleep and I get a text or any notification, the ambient screen wakes and will initially make the entire screen flash white very quickly.
I do not get a flash of the screen in any other scenario when the phones on, it only seems to be when the screens totally asleep and the ambient screen wakes. I can unlock the phone or hit the power button to fully wake the phone to my home screen with no flashing. Its not every single time, but its very often. I do notice sometimes when it doesn't flash the whole screen, the time or text on the ambient display will be at full brightness when it first wakes for a split second and then will go to the dim text Im used to seeing.
Replaced the phone through Verizon. Got another brand new one with the same exact problem. This one even flashes on reboot occasionally just before the white "Google" screen pops up. Google had me send them a bug report this time and are supposed to be having their dev team look at it.
WHY.
Mine did it once

I've also now noticed mine will flash in Instagram when I "like" something lol. Just the picture flashes within the app itself in that case, not the whole screen. Such a weird thing, that may have something to do with the app on the new pixel? I don't even know anymore.
I just saw the white flash. It was only for a few ms but it looked like a full brightness white flash on the whole screen. I had just set my phone down and I think the AOD was coming on.
Weird.
Yeah I have a feeling this is happening on way more devices than we're reading about. I hope it's addressed. Sometimes my notification audio cuts out real quick too. Hoping it's just all memory related.
I have this weird kind of screen flickering on my device as soon as I use the fingerprint area to turn the phone on. It is very faint and fast but its like static lines for half a second when the screen comes on??

Strange, I haven't had any issues like that using the fingerprint reader or just hitting the power button. Mine are all directly related to ambient screen waking.
My Pixel 3 is doing the same thing when I unlock it. Flashes like taking a selfie... I have even looked for the selfie to no avail.
It does not do this regularly, very random.

Same here. Sometimes when I tap the screen to wake it up, it flashes. Just did it a minute ago before I wrote this.

I just charged the Pixel face down; during the charge I picked it up to check the progress and I got the screen flash ~2X out of 10.

Report it to Google. I feel like it's something they're aware of (I hope) but support certainly isn't saying so if they are.
I saw a post on Android Police about bug trackers and read in some of the comments that people were having problem with screen flashing. Some of them said it was related to the always on display. Mine was flashing like white static lines. But it was only for half a second when you turn on the screen and it didnt happen every time, it was random. I turned off the AOD and it never happened again. Kinda sucks cause I like AOD. But that tells me it is a software problems and not hardware.
I turned off AOD too, for 1 day; the next day I turned AOD back on. I have not had a screen flash since (a few days now).

Try rebooting. I bet it's still happening you just may not be noticing. I've had my AOD off for a while and as soon as I turn the new notifications option it comes back. Not every time but still often.
I'm having the same issue, doesn't happen all the time but I can reproduce it usually by unlocking the device, locking it then when ambient display comes on, unlock it and the screen flashes/flickers. I've only managed to do it with ambient screen set to always on.
I've RMA'd this morning so I'll report back when the new phone comes.
I hope you RMA's for other reasons too because it is likely that you will get a phone with the same flickering problem. I think it is a software issue esp since it goes away after we turn off AOD.

I just find it strange that people are having the flicker in different scenarios, like mine is only when ambient is set to always on but other people are having the issue when it's set to double tap etc. Anyway I guess I'll see when the new phone comes.

Yeah let us know please once you get the new phone. It seems like it is hit or miss with people so you might get lucky and avoid it.

Quick update. My new phone arrived this morning and I've managed to get the screen to flash once so far where as my old one would do it 8 times out of 10. I feel like this is a poor display hardware problem rather than software.
I believe or rather am hoping that because it only happens when you turn on AOD that it is a software issue and not a hardware one. The only way something will be done is enough people complain on a bug tracker.

Green and purplish screen?

This is what my son's One Plus 7pro screen looked like one morning. No physical damage just unreadable display. I hooked up a HDMI cable to a monitor and it displays fine so it's not software. Touches are responsive and I have called customer support with no solution. I did a factory reset and it still had the issue so definitely not software related. Didn't use the phone for about three days and now it's working fine. Am I going to have this issue again? Anyone heard of this problem with a purple and greenish display?
Probably something wrong with the LCD or LCD cable
Looks like screen burn-in to me.

It's less than a month old and the images changes just can't make crap out

In that case it's probably a faulty ribbon cable or something similar, can't see much more from what info we have
(Also, do ask if he had left the display on for a long time, maybe overnight, on high brightness. If so, it's a burnt screen.)

I think the network has been replaced by a new machine if it is in warranty

Heya, I have the exact same issue with my One Plus 7t Pro. The screen looks exactly like that and is perfectly responsive (except the fingerprint reader can't recognise my finger) but unusable due to the discolouration. Did you ever discover what the issue was? Did you send it off for repair?

One Plus customer service said they would repair but I couldn't get a ticket created because I bought it through Sprint. Weird loop of going back and forth through both companies. I did a factory reset and the issue didn't fix but twice it fixed itself. The first didn't last too long before the problem came back. The second time it just fixed itself and has been working fine since. My son was sleeping with it at not listening to music and I think it was a heat issue. After factory resetting it and turning it off, I let it sit there for about a day then when I powered it back on, everything was fine. Has been working great ever since. I make sure he doesn't have it on his bed at night anymore. My guess is it's heat or too much pressure on the screen. No way of figuring it out. Not sure if that info will help you or not. I would contact one plus support.

Heya,
Thanks for getting back to me quickly. I also purchased through a third party, so I have contacted them regarding repairs. Did your son mention anything regarding water damage or was this not a concern? I'm feeling a little more confident that it is repairable, cause it looks pretty scary!
I thought about water damage he did have it in the bathroom while taking a hot shower.
