flickering display areas - OnePlus 8 Questions & Answers

Hi, I am on latest 11.0.1.1 global. I actually don't remember that I had these issues on v10.x, but definitely since v11. I use 120Hz, FHD+ with all color optimizations turned off and with standard OP launcher.
I experience some flickering of the whole display or just parts of it in many situations. It starts to get annoying.
Examples:
1) open the hidden app menu. Right before it opens the whole(!) display flickers white once. Good visible since the top bar next to the camera hole flickers once.
2) Go here and try to type in any number. The moment the GBoard comes up at the open, it flickers just the bottom part.
3) Lock your phone. When you fire it up and the Lockscreen gets unlocked, if flickers once.
There are so many more situations but the depend on some apps.
Is this normal behavior? How to fix this, if it is not?

Flicker when lock screen switches off

Hi, I pick up my phone to check the time; i.e the time appears for a few seconds on the lock screen then screen turns off. I am using one of the round clock-face screens.
Sometimes (not always) when the screen is switching off, some of the content from my home screen flickers on screen for a fraction of a second (notification icons, the digital clock and something at the bottom), as white text on the black background. It's not catastrophic but it is enough of a flicker on the screen so catch my eye and make me look over at the phone.
Has anyone else seen this and/or know how to fix it?
Mine does it too, and I don't think there's anything we can do about it.
Which update are you running (1.15 or 1.21)?
I used to noticed a slight flicker on 1.15 not to the extent that youre describing, but it went away on 1.21.

I'm running 1.25.400.3.
It seems to be doing it less now, maybe only 1 in 5 times. I haven't changed anything (been running that version since I first got the phone last week).

Display is slightly blinking in specific conditions

Yesterday i noticed something strange in my OP7p and i'd like you to check whether something like this occurs in your phones. Issue, which i will describe occurs only when i have 90hz refresh rate set and the low brightness of the screen with the auto adjustment of brightness turned off. The easiest way to see that is on youtube application with a dark theme. When we start a movie on the full screen (horizontally) and watch it for a few seconds, then go back to the vertical position, there is something like weak but visible blink of the screen, or a minimal colours change. It can be noticed in other apps, e.g. on facebook. Seems to me this is a software problem, beacause the same phenomenon doesn't exists when we set 60hz refresh. I would be very grateful if you can check it on your phones and give me a know about it.
I don't usually start videos in full screen mode and never noticed it but yeah definitely does a white flicker.
This is the highest brightness I could get it to do the flicker at.
Thank you for an answer. Personally i am able to see this flicker on a little bit higher screen brightness, but maybe its because im sitting in a dark room now. I was worried cause sometimes i see it during the normal usage of phone, and if only my OnePlus would be affected by this flickering i could still return it or exchange for a new one. It isnt very disturbing however interesting is whats cause of it.

this is usual for EVERY Oled screen and is called jelly effect...
You might want to try the DC dimming option in Settings->Utilities->OnePlus Laboratory.

From what i know jelly effect appears while we scrolling some content and propably that's not what i meant in my first post. Also flicker in my case is only visible on 90hz refresh rate.
I have galaxy s7e as a second phone and that effect doesn't happen there.

Touch lag issue when using Adaptive smooothness

I got my Note 20 Ultra back on November and encountered an annoying issue when Adaptive refresh rate is turned on and watching YouTube videos. When YouTube first starts the display will run at 120hz, but after a few seconds it will drop to 60hz. When the refresh rate drops, the first touch of the screen is interpreted as a touch and hold instead of a single press. The display will then jump back to 120hz, but the display still thinks I'm pressing and holding the screen when I've already let go. If I then touch the screen again while in 120hz the phone thinks I've done a double tap (presumable completing the first tap and then immediately registering the second tap), which causes the video to seek forward or backward, depending on where I pressed on the screen the second time. If I tap the screen the one time but allow the screen to drop back to 60hz after it jumps to 120hz from the first tap, then the first tap seems to be ignored as my second tap acts like a tap and hold again.
What's interesting is that as long as the display stays at 120hz, all taps after the scenario above work fine. A single tap will open the playback overlay (pause/play button, seek arrows, etc) like it's supposed to, but once I leave the display alone and it drops to 60hz this whole problem starts all over again. Since adaptive refresh is tied to the brightness sensor, this problem does not present itself in a dark room since the display stays at 120hz in a dark room. Also, if I turn off adaptive refresh rate and have the display stay at 60hz all the time then the problem is not present either. I also will occasionally get non responsiveness on Brave Browser but I can't say for sure if they are related.
This has frustrated me so much I did a factory reset and interestingly the issue did not re-appear at first with a fully updated YouTube. Once I updated/installed other apps (including Galaxy store apps) the problem returned. I don't have display overlay apps installed, so I suspect it's a Galaxy store app but I can't pinpoint which one. I don't believe this is a hardware issue, so I'm curious if anyone on the thread has had a similar issue. I'd like to report this to Samsung but I have no idea where to even report this.
Sounds like you've figured it's a software program. You should update one at a time and see if you can pinpoint the issue. Try to not to install 3rd party software until all you need to update gets updated and phone is working fine.
Or
I would say try using a package disabler and try disabling the apps you suspect to see if any improvements. It might not be a Samsung app as others would be facing the same issue you're having.
As always don't restore settings/app data from backup etc other than media, messages, logs.
I'm using adaptive and everything is working fine on my end. Snapdragon variant here. Albeit I keep a number of Samsung apps disabled as i don't use or need them running in background for no reason.

Can you provide a list of apps which you have disabled through adb?
have you tried diff version of youtube that can help

I use package disabler pro bought from their website. It gives me a great on demand enable/disable option.
My use case might be a bit different from yours as I have about 160 packages disabled at a given time. I guess I can provide a list and you chose what you want from it.
I'll try uninstalling apps again to see if the problem can be resolved that way. On the latest version of Youtube it worked fine before I started installing more apps. I kind of don't want to do a full factory reset but if I have to so I can narrow that my be my only option. I'm wondering if there is another software I can run on my phone to see if any apps are interfering with the display or adaptive refresh rate?
I ended up doing a factory reset on my phone. The issue went away for the most of the day but returned again by night time. Same issue - when at 120hz and drops to 60hz the issue is present. It's not just Youtube, it's on any app, including the home screen. The first tap is always interpreted as a tap and hold, so single tapping an app icon brings up the tap and hold menu, and single tapping on the home screen brings up the home screen customization screen. Another test I did was turn off auto brightness, then turn my brightness down to the lowest setting. After that the display stayed at 120hz and the issue did not return until I either set the brightness up manually or turn auto brightness back on. I also tried in safe mode, and the issue was not present there either, but I can't tell if the device every went into 120hz or not since all 3rd party apps are disabled. At this point I have no idea what it is. The app setup was fine during the day, no new apps were installed, but the issue returned. Seems like I have no choice to but turn adaptive smoothness off and leave it at 60hz.
Just to add a little more interesting information here. I had someone else use the refresh rate monitor app on their Note 20 ultra (Tmobile variant), and their display operates differently than my Verizon variant. On the Tmo variant, when the screen drops to 60hz and the screen is tapped, the refresh rate drops to below 60 (12, 34, 48, etc) but then goes back up to 120hz after the app opens. Mine just goes immediately to 120hz and then gets that tap-and-hold behavior. So clearly the screens software or firmware is behaving differently here. I'm wondering if we have any other Verizon variant Note 20 Ultra users on this forum that could also test?

Screen Flickering

Hey guys,
I have bought oneplus 8t after it's launch and never had seen this issue before. From today onwards I'm seeing screen flickering on the lock screen. I might have missed this before or this is just in my device. I usually put dark wall on the lock screen. Yesterday I changed that to a bright one. The flickering is visible when the screen brightness is really low and screen is turned on and the first time is really bad, it is taking time to adjust and the following takes less time to adjust.
Please let me know if this is a rare care in my device or this is happening to everyone.
Edit - I'm also noticing weird color shift in chrome browser. White to warm white color
Color shift in chrome was due to a chrome flag, disabling it fixed that one.

OnePlus 7 - OxygenOS 11 stable - Issues

Hello,
Recently i upgraded my OnePlus 7 to OxygenOS 11 via OTA, and here is a list of a few annoying bugs(features?) that you'll need to know before upgrading:
(Note: I performed hard reset after upgrading, so any bugs here will be persistent and not because of some fixable issues, unless you are rooted/want to use adb maybe?)
(Also, this is the stock OOS 11, not rooted, and no modifications)
1) I'm not sure if it's just me, but the device heats up much faster. Though the temperatures here are high, I tried to maintain as close to a lab condition as possible, maintaining 30C ambient temp. Evaluation was done with a session of Call of Duty Mobile, and Youtube 4K video loopback test. Avg temps are: CODM : OOS 10: 41C, OOS 11: 45C, Youtube: OOS 10: 37C, OOS 11: 38C
2) Performance hit in games and frame drops (CODM, outside the ambient temperature maintained conditions), could be due to overheating? (As i mentioned, ambient temps are a bit high here). Also SystemUI lags sometimes. Adding to that, trying to bring up notification panel while playing a demanding game (like codm), the SystemUI (notification panel) opening animation is really choppy. (Is there some graphic driver issue?)
3) Brightness slider very slow to respond (seriously? Have to wait for 3 sec for the brightness to come up/go down on manually moving the slider)
4) Again, this one could be only me, but the audio seems to be a bit low after the update. All the ringtones and default notification sounds, with the same volume levels feels lower than how it was on OOS 10.
5) Battery drain - Device heat up and performance issues, translate to higher battery drain
6) This may not be a bug, but it's a change that i don't quite like (at least provide options?) : Double tap to wake doesn't give a vibration feedback like how it used to.
7) Everything, including UI and default font size is bigger than what I'm comfortable with (no, changing the font/display size doesn't give the expected results). But there's a workaround: Changing the display dpi from developer options from 384 to 420.
8) I had several app crashes (Instagram, Photos) even after disabling Android System Webview as suggested by some. But this issue seems to have been fixed magically for now.
9) This is a change, but to actually poweroff/reboot, you will need to reach your finger to the top of the screen with the new UI.
10) DC dimming has been removed
11) Weird QC issue-Someone thought any greyed out field in settings is because it's not supported by phone or HEADSET... Even in Private DNS settings.(See screenshot)
12) Natural colour calibration has a weird yellow tint (sRGB profile works fine tho)
13) Lots of missed/delayed notifications. Many times, notifications from apps like Instagram, Telegram doesn't arrive on time, with delays from 2 minutes to never arriving at all. Whatsapp seems to work most of the time. Sometimes, notifications don't make sound (weird), but only flash on the screen (Yes, I've verified all my notification settings, and I've set everything to make sound)
14) Now this might be a personal preference, but I don't quite like the way OxygenOS is trying to mimic OneUI (Huge heading and small contents beneath? Not my taste.) This style is followed in the phone, messaging, contacts, calculator, etcc
15) Quickly switching between recent apps, there's a split second of a black screen that appear before the app UI is displayed (not complaining, but this was not present in oos10, it seamlessly moved from the preview of the app on the recent apps screen to the actual app ui without any flickering, and no, this is not because of dc dimming being off or anything)
16) Google Play Music is still not removed (seriously, why still have it if it can't be used?)
17) FileDash - No longer has the DNS resolver for one.plus address. You will now have to manually type in the address displayed by filedash in your browser. Also, it still uses 2.4GHz and not 5GHz.
Edits: Added more bugs/missing features
Hem981,
I can confirm #7 is an issue on mine as well.
The power menu is an android 11 change not an OOS change.
I upgraded from OOS 10 to OOS 11 no wipe and don't seem to experience the other issues that you are having, except the obvious changes they made to the firmware. Have you tried clearing the dalvik-cache and rebooting? Mine was super buggy before doing this, but then again I just upgraded without wiping.
One issue I've personally noticed is the cell radios were a lot better on OOS 10, and I'm assuming that is the cause of the battery life to be worse.
Another that could be due to doing some debloating is when I take a screenshot and the little preview pops up in the bottom right corner if i click on it the UI will freeze after clicking back. The Nav buttons still work, like you can click on recents and the recent menu appears, back and home work but the screen is frozen otherwise until I force a reboot.
Yeah, I've tried factory reset and then wiping dalvik-cache... The performance was better before i performed the factory reset, i think. Anyway, there are quite a few games/apps where the performance impact is easily visible. Also, the power button thing is an Android change, but i really hoped OnePlus to have done something to make it more easily accessible (OOS is not pure Android). I couldn't find the issue with the cell radio you mentioned (as I've tried in areas in which i already had poor reception, and the performance was what was expected). Anyway, I really hope some of these (at least the performance, battery drain and the brightness slider issue) will be fixed soon over updates.
(For me, the SOT has gone down from 9.5 hours to 7 hours under similar use cases)
Yeah SOT has definitely taken a hit on mine as well, standby time seems the same. I also have noticed that the screen brightness needs to be set higher for the same brightness as OOS 10. The cell radio sometimes seem normal, but most of the time they are about 5-10 dBm higher at my house. I'll probably give a clean flash a try this weekend to see if it clears up.
One more issue found:
Weird red tint on screen auto dimming
The whole display has a weird red tint just before the device is about to lock/turn off screen after the timeout, when the display dims. It is easily noticeable if you have a white screen displayed. It only happens if you have set the brightness slider to anything other than the bare minimum (even a single step above the minimum brightness is able to replicate this issue)
I found something interesting: issue #3, the brightness slider being slow to respond to changes, seems to be fixed by disabling all animations from developer options. Should the window animator duration scale have any effect on the responsiveness/quickness of display brightness adjustment? I think that's stupid.
Also, I am starting to thing we need something like 0.1x duration scale for the animations (all animations on Android, or at least OOS), because honestly, with each new implementation, the animations are being too slow that it degrades the whole experience. 0.5x feels a bit better, but i really think something like 0.4x would match the animation speed of android 10.
You forgot to mention the vibration motor effect which has deteriorated since the update. The device now feels like any other cheap device.
It's kinda weird in my situation, just upgrading from 10.3.8 using an old version of xXx NoLimits to 11.0.0. The phone was super buggy when I first installed, but after rooting, wiping the delvik cache, debloating, removing the xXx module, and time to settle in the only issues I have are the screenshot popup, and the lower cell signal which I'm sure is causing a hit on battery life.
I was going to reinstall this past weekend, but for the time and inconvenience it's not worth the time compared to the minor issues I have.
Edit: Even the screen resolution seems normal now.
Again, don't know if this is an issue for anyone else (and i don't think OnePlus is going to change this): While everything else became bigger on the phone, the buttons/number keypad for typing in the screen lock pin became too small.

Hi! Oneplus 7 ownere here.
Try to answer all the points:
1) i don't notice any difference between OOS10 and OOS10 on the heat of the phone
2) I don't know for the gaming performance but i don't play any games...overall, the performance are good, no system lags or freeze BUT I have the same issues with the notification...when i tap a notification, I often have delay, maybe it's just the animation but I remember the same issue on a Oneplus 8t that i tried for 20 days in last November
3) same issue here, very annoying
4) not just you, have same issue
5) battery drain is the same in my case, in standby maybe is less than before
6) me too, but maybe they change this as they planned?
7) yes, same thing. i changed the DPI from developer options too
8) no crashes here
9) this is an Android 11 change from Google, maybe they don't want your device to power off ahahah
10) never had this problem luckily
11) don't know, never tried this
12) i noticed this after reading this point, true on my device too
13) i faced the same issue on the notification sound, the other things works fine
14) me too, if i wanted One UI, i would have bought a Samsung...
15) sometimes happens to me, maybe it's bad ram management?
16) this is ridicolous, why they doesn't remove this app??
17) never tried
I also have an issue on the vibration. Now it's HORRIBLE, i have disabled because it's unusable
So, this is my question: change phone or rollback on android 10?
There's one more addition to the list: Always on display sometimes seems to override the notification lockscreen privacy settings. I have some notifications put as "view private content only when unlocked", but the notification contents are visible just when it arrives on the always on display (though it's content is hidden in the actual lockscreen)
I've reported almost all of these bugs, and hopefully we will see new updates fixing most of these.
Can someone on OOS 10 on OnePlus 7 confirm if the "style preferences" settings in sound settings is greyed out while the output is phone speakers (or no other sound output devices connected)?
New hotfix patch OTA rolling out now...
Here is what's fixed and what's not:
1,2 : Yet to test
3: Not fixed
4:Fixed
5: Yet to test
6: No changes
7: No changes(or not easily noticeable maybe?)
8: Not encountered any "ghost" app crashes yet
9: No change
10: DC Dimming is not back, so no change
11: Not fixed Is it that hard to remove 'headset' text from the UI?
12: Don't know if it's because my eyes adjusted to it, but it seems a bit better now
13: Not yet tested
14: What can I say?
15: Fixed
16: The ghost of Google Play Music still remains
17: Not fixed
Edits: Nothing much is fixed
Performance: Marginal improvements
SoT/Battery: Even worse. Getting almost half the SoT I got on OOS 10 under similar use case and network/tenperature conditions
Ghost app crashes reduced a lot (that might be the only fix) , but is not completely gone (saw that 1 or 2 times)
Haptics is still as bad as before
I'm just worried about this weired bug which has rendered my parallel whatsapp very difficult to use to share media. Any fix for this is highly appreciated - https://forums.oneplus.com/threads/whatsapp-media-problem.1411292/
Thanks and regards
OOS11 - Stable
I have no problems on my device until now (for games I dont know why I do not play)
I noticed, because I have tried both roms(beta4 & stable).Open Beta4 has better "battery management" than stable! Αs strange as it may seem but is a real for me..
Well yes .Battery drain higher than openbeta4
wifi works fine to 5ghz band & generally my device works quite well so far. Patience is needed and all problems will be fixed...
https://postimg.cc/gallery/YtQpVDm
After the recent OS 11 update ,the media in my device ( photos and videos) not being shown properly in Whatsapp. Some of the videos and pictures which I've already deleted in the gallery are appearing again only in whatsapp in unsupported file format.
I'll be glad if someone confirms that it's a bug in OOS 11.0.2 and that my phone is not the only one which is affected.
I'm using WhatsApp and Parallel Whatsapp. Also have setup a Work/Office profile on my phone.
Does anyone have any solution to this issue?
Thanks and regards!
For me, wifi no longer works. Whenever I try to enable it, it just immediately turns off. It also no longer recognizes my SIM card.

Try wiping cache from recovery
Update 11.0.1.1
I feel like this is a big joke.
Even more battery drain (yes, i did a factory reset).
Brightness slider issue still not fixed.
Performance still degraded (but i think there is a little bit of improvement)
Not sure about Wifi issues as i never had them.
Weird red tint on screen dimming
Still many ugly and inconsistent ui elements
Color profile is back to being broken (the yellow tint returned)
Update: I've started having the wifi disconnection issues, after 11.0.1.1 update. This is way too annoying.
