Question Poco3-Sceeen flicker- After Pixel rom - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

I changed my poco f3 to pixel experience, everything working fine but I now after 3 days face some little flickers in screen screen (screen blinks) mostly when I open the apps. Then after few time it stops.
Is anyone else facing this issue, or any solution?

if you have minimum refresh rate and 60 and maximum at 120 then that;s the culprit. Keep both at a120 and no more issues

exposure / autofocus flickering

Very happy with the HTC 10, certainly with audio quality when recording live music.
Anyhow: I have a problem with recording video in dim light situations: the video (whole screen) flickers now and then.
In good light situations (outside daylight) the issue seems not to be there.
The flickering is already visible in the live preview during recording (but even worse: also in the final recording)
Note that when you switch to "photo mode", the flickering is not visible in the live preview.
I think the cause can be that de Auto exposure is switching too fast, or is interfering with something.
For a very short example clip see: (here you see the flickering is also visible in the final recording)
https://www.youtube.com/watch?v=2brDkD4Zjn8
This may look like an "artificial situation", but here also a real life situation (with nice live music )
https://www.youtube.com/watch?v=ujDZtrS0NXc
(flickering: second 1-3, second 15-18, second 38-41)
Firmware HTC 10:
1.95 / 1.95.401.3
Camera Version:
8.10.763406
Question is:
- Are any users experiencing this issue?
- Do you think this is a hardware issue? Or software?
- BTW: photo's look perfect, so I hope it is an issue that can be fixed.
- In daylight the flicker issue also seems not to be there
Tried so far:
- Deleted camera data / camera cache
- Cleaned the camera lens / autofocus lens
- Tried other camera apps (same issue), so if it's not a hardware issue, the issue is not in the camera app, but probably in the firmware.
Any ideas?
Update:
Maybe it can be related to 50 / 60 Hz interference ?
Also see: http://forum.xda-developers.com/htc-10/help/camera-flickering-video-recording-t3476842
Note: on my Mi5 I don't have this issue
BTW:
See this clip: Using 30fps video can create flickering artefacts in artificial light in PAL regions.
https://www.youtube.com/watch?v=KxBB8HmJB6A
Currently the HTC 10 indeed records in 30 fps (actually 29.97), so maybe that is the cause?
If this is the case, then this issue probably only affects users in Europe ?
-> Update: see comment below: flickering is can also be reproduced without electronic lights
- Update: can also reproduce the flickering without electronic lights, so the 50/60 Hz looks like a different issue.
- The flickering seems to happpen in low light situation, with backlight (from a window by example), where +/- 50% of the frame is in low-light and the other 50% has backlight
I get serious flickering both with photo and video if there is ANY light interference in low light situations.
Example being aiming camera sideways on our couch (so 90 degrees away from TV on far wall), low light as evening, the TV is enough to send my phone in to overload, its more or less impossible to get a photo or video due exposure and who knows what changing what seems like hundreds of times a second, drives me nuts I have given up trying to take shots in such situations.
Can put in pro mode, then the colours jump all over the place from that interfering light.
edit: just to add to this, the TV of course is changing colours / light constantly so I believe that is what makes my phone have a meltdown. If say the TV light is static the camera will stay static I believe with little to no issue.

Did you try if the problem is also there in other camera apps?
Try by example open camera.
In my situation the flickering is not gone, however, i did see that the "banding issue" is less in open camera, unfortunately it doesn't help against the flickering I experience.
BTW: what firmware are you on?
I have not tried another app, no
Can try that tonight though (8.21am in the morning now)

I also have made a topic with this issue. I've tried with Camera FV-5 which has the interference option to set 50/60 Hz and it makes no difference. With the TV i haven't any trouble making video/photo. No bands passing by.
The conditions are: environment with low illumination (the lower light the higher visible effect) and any source of electric light.

What is your firmware version ?
Still not clear to me if this is an software issue, or that we maybe have a device with a hardware issue.
This beacuse I don't see a lot of reports about this issue. If this would affect all users, I would expect more reports.
I have the same issues, combined with some dropped frames AND a weird panning effect (have a look at the HTC 10 Camera Thread).
You can check my videos here , here and here.
But, if you put the slider for the exposure all the way down, or lock AF/AE to a bright source, the flickering disappears, no matter if you pan from a bright to a dark area or not.

Neither to me if it's hardware or software. I have the 1.92.709.1 firmware of the 10h unlocked version.
Due to the variable conditions, i tend to think that is fixable via software update, but well, i don't know...
Hi, I've the Taiwanese version of HTC 10 and I can confirm this issue. It should be noted that D4v3 is right. If you lock AF/AE the flickering effect dissappear. Please long press over a light source until AF/AE block message appears. You'll see the problem is gone.
I guess the problem is firmware related because if it's a hardware issue why can we fix this blocking the AF/AE? I think it's related with how the firmware manages changes of lights.

I agree this looks like it could be fixed with software, but the fact that so few users report this issue, makes me think it is not affecting all users.
If it would affect all users I would expect a LOT of reports, since in fact recording in dim results in very poor quality.
@ Jadraker is saw your threat about a new update: 1.96.709.5 -> Does this update fix the issue?
It could be too that not all users uses the camera to record video in such low light circumstances. For example, I noted this issue when I read your post. It's probably that without reading the post I would never realized that flickering.
About the update I'll test the phone at night and I'll publish the result accordingly.

Unfortunately the flickering issue wasn't fixed with the update I received.

The question is if HTC is even aware of that. Don't know how to point this out to them, since it's really annoying and not just happening in low lit areas but also during daylight
It seems HTC 10 is not the only device with flickering issues while recording video. Please see: http://forum.xda-developers.com/galaxy-s7/help/samsung-s7-camera-flickering-t3337032
I don't know if it is the same problem but at least it's very similar, isn't it?

I could not find a lot examples on youtibe of the S7, but based on the text I would indeed think it is similar.
I also own a Xiaomi Mi5, and compared it with the HTC 10 in the exaxt same situation, the mi5 doesn't flicker at all, whilte the HTC 10 flickers.
It looks like the Mi5 is change the exposure more gradually.
I think there are 2 issues with the HTC10 camera:
1. Flickering caused by (eletronic) light in dim situation (scenario: +/-50% of surface dim +/- 50% of surface bright)
2. Issues when panning the camera
I find it still difficult to define an exact reproduction path.
But part of the problem also seems to be white / shiny surfaces, see this video: https://www.youtube.com/watch?v=7PZQYZvJ8lI

Touch screen sensivity issue especially when it is on a flat surface

Hi, I am a satisfied user of the global version of Redmi Note 5 Pro, but in recent days I have noticed an imprecision in reading touches on the screen, especially when the phone is staying on the table or on the bed.
The most annoying thing is that it doesn't take the swipe from the bottom edge of the screen and doesn't trigger the home gesture.
On the phone is installed MIUI Global 9.5.13.0 (OEIMIFA) Stable.
Anyone else noticed this issue?
Sorry for my bad English :silly:
Just tried it out (same version and also using full screen gestures) and everything was fine. Never had a problem going back to the home screen or recent apps while the phone was on a table.

T520 Screen rotation issue

Hey guys, running the latest lineage 14.1, and for several months I've been experiencing this annoyance where if I long click something, the screen will rotate 90°. I've done several full wipes but no improvement. I know the sensor is fine though because when I physically rotate the tablet the screen orients correctly. Any guesses? Thanks.

Redmi Note 8 Pro Gyroscope Problem

As some of you guys might already know Redmi devices have Gyroscope issue but it get fixed with Calibration (in my case temporarily)
previously in Android pie, while playing pubg Gyroscope was working fine with no issue, but i had the issue with my gyroscope while charging where my aim was moving on its own even on a flat surface. but it used to happen while charging only (& my Gyroscope setting is always on with 190 sensitivity just for the info)
And now in Android 10 it happens after every 10, 15 minutes doesn't matter how many times i 've calibrated my device but it never get fixed permenantly.
But I know the temporarily solution:
About > All Specs >Tap 3 times on kernal version > Press on the top right corner & go to additional tools
Acc Calibration Tool:
Accelerometer ( not all values are zero) just calibrate your accelerometer, & your device should be on a flat surface
Gyroscope Calibration Tool:
Gyroscope (all values are zero but some are in (-ve) zero don't know why ?)
Calibrate Gyroscope - also device should be on a flat surface
check your Gyroscope issue with 'Compass app' and values should be constant on a flat surface
You can also use 'Gyroscope Test App'
in my case:
mine only gets fixed after calibrating and waiting for 20 seconds at least. i use Gyroscope test app to know whether my Gyroscope issue is fixed or not
and mine never get fixed after device reboot.
seems like this is the Hardware issue. i tried to hard reset changed rom to miui 12 came back to miui 11 but the issue is still there.
and calibration is the temporarily solution for me until i don't reboot my device.
didn't tried custom rom yet.
Did any of you guys have the similar issue, or any of you know how to fix it? Please Help!
Strange seems like no one is facing this issue
I am facing the same problem from past two days on my redmi note 8 pro . It can be fixed temporarily by rebooting the device . But after opening CIT by tapping kernel version my accelerometer is not showing anything it's blank

Sorry to say that i cannot help ??
Facing the same issue. Screen doesn't rotate, accelerometer and gyroscope values are blank in CIT
On a steady table using the built in level function in the compass app was showing 1 degree (table not perfectly flat) for a couple of minutes and now it`s changed to 2 degrees and has been showing that for over five minutes, The only problem i have had is if i am on the home-screen in portrait mode with the phone on the table and click on my browser (opera) the screen will change to landscape mode, Then if i lift up the front of the phone the display will change to portrait mode, It does this with a few apps and it can be a pain, I could download a screen rotation all to fix the problem if i needed, So no major problems and i am not phone gamer, I prefer my 360 or PC
i hope this work for you
If your gyroscope is temporary work after restart you can fix it with my guide:
1.restart your device
2.open the cit test (multiple tap on kernel number)
3.calibrate your gyroscope in flat surface and make sure your gyroscope is still active
4.follow the other sensor calibration until you complete the compass calibration .
4.you can exit cit and check all your sensors
note:do this as fast as you can

:::my note8 pro also has same issue
i also tried all the tricks, calibration and all stuff but it only worked temporarily. if i place my phone on flat surface, it stops moving for some minutes but starts moving again.
i even tried changing my miui version from global to indian varient but the problem is still on. these days when i press the phone on top left corner, the gyroscope moves even more faster and when i press it around middle, it starts moving in opposite direction but never stops. somewhere i have hheard that this may be due to hardware issue, because of heating.

Touch Latency

I recently bought the OP7T. Everything works fine to me but while playing fps games like codm and pubgm
I can notice touch latency lag
Is this common in all 7T's or I am the only one facing it
I checed the OP community too there were also some people with same issue but still dont know if its only in some devices or in every 7T
My phone is in RMA period so if its my device issue i can replace it with new
Need help
Can you describe in more detail what the problem is? If possible, record a video please.
Facing the same issues after the recent update like if using the back gesture it sometimes lag on that screen also chrome has freezing issues while gaming also sometimes force stop after being having 8GB of RAM.
