Blackview A5 Green Screen flickering while playing videos - Android Q&A, Help & Troubleshooting

Hi guys,
I just bought a blackview A5 to find out what you can get for about 45€ It's incredible fast and everything works quiet well except playing videos. When I'm playing videos in an app like youtube or tagesschau (german tv channel) I've got a green flickering in the picture, especially if there are a lot of blue areas in the picture. It's like blue area become green then switching back to blue then green again and so on...It's looks a bit like an error in the video driver or video codec...I tried to update the firmware...but still same problem. Does anybody has an idea how to solve the problem? Do you think it's hardware related?

On developer option. Turn on disable hw overlay on developer options. If dint work turn off completely developer option. The flickering issue will solve.

Didn't work for me! Have the same problem.

Screen flickering while recording

Hey guys...
I'm just wondering if i'm the only person having this problem. Before the .15 update, when i recorded and used those stupid effects (make eyes big, face small...etc) it was recording fine. But today i was trying to shoot a video using the effect, and when i played the video it had a screen tear/flicker on the top of my screen. Can anyone check if they're having the same problem?
The screen has a \____/ kinda shape flickering on the top of the screen when i'm playing the videos.
thanks
This is a BUG! I have this problem when i hit a recent apps botton...Please turn on screen and then 20-30second dont touch your screen when is in homepage then go to settings and do you see any homepage widget,icon like ghosting (screen burn)?
Yup
I have the same issue when using the front facing and Rear facing camera w/ video effects. Hopefully it gets fixed soon. Running Virtuous Rom

[Q] Video playback diagonal coloured stripes across...

About 50% of the time on Youtube and ALL the time on NowTV I get a thick coloured stripe at the bottom of the screen and sort of coloured diagonal lines across the screen. The playback is sort of washed out behind the lines.
I'm using Nameless 4.4 and have tried clean installs, but it obviously isn't a widely experienced problem with the ROM since I can't find anything on the Nameless thread.
Any ideas would be brilliant as it's really really annoying.
I would change ROM but NowTV doesn't run on anything rooted (even with root disabled) such as aokp/CM11/Slimkat etc.
Go back to stock firmware to test if it's a hardware fault.
Did you come right?
I have the same problem.. I have the 12.1-2015-05-31-UNOFFICIAL-i9300 custom rom on my galaxy s3.
Playback via. the default youtube app is fine, but playback on my TubeMate app gives me the same effect as you have above (looks as though it's playing on an old tv with bad reception)
Worth mentioning that I have 2 other android devices with TubeMate that are not using custom roms, and the playback is fine
I've just written to the tubemate guys.. will post anything useful here

Dark scenes difficult too see in movies

I have a Samsung Galaxy Tab S3 and it's great but I can't figure one thing out. Which is the screens contrast. Dark scenes in Netflix or VLC player are too dark and hard to see. I tried different brightness settings, with/without blue light filter and the other color correction option for cinematic mode but nothing really works properly.
Is this an issue with the tablet or is there another setting to change the contrast or something?

I also noticed this with Netflix. Was hoping that turning up the brightness would help but it doesn't.
YES, YES, YES, I am shocked this isn't widely reported, I couldn't find almost anything about it and I've been searching for quite a while.
First of all it is really crazy that popular apps like plex or netflix don't offer any capability to change the brightness of the video played. No, we don't change the colorspace, black levels, bla bla bla.
I DID find eventually a solution (the ONLY one that works, a bit clumsy as it is): http://phandroid.com/2016/03/22/twilight-app-reduces-dark-contrast-on-samsung-galaxy-s7/ (yes, it's for the S7 and yes I did notice there the same issue, which makes it even crazier that it isn't something widely known and fixed).
I just picked up an S3 last night and I'm having this same issue. I watched the opening scene of The Defenders on Netflix, and I could hardly tell what was going on. Rewatched it on a proper display, and you're clearly upposed to tell it's Danny Randy much earlier in the scene, but I had no idea in the S3 until a blue light was clearly shining on him from above.
I used Twilight on my Nexus 7 because it lacked a night vision mode, ala blue light filter on the S3. I'm not sure how that can really help. Surely other people have found more elegant solutions to this problem? I've opened up other media files and they're all simply too dark. I get it's an HDR screen, but surely it has a mode for non-HDR content!
Do oled display have a blue light problem, I though it was only really a led thing.
John.
Might be an inconsistency with the displays. I have no problem with mine. Not getting any lag either but running a heavy debloated rom also. Battery life could be better. It's stupid you can't turn off the Wacom digitizer when s pen not in use. On my note 4 when I lost my s pen battery life was terrible because the Wacom digitizer stayed on. Should be an option in settings to turn it off. If anyone knows how please let me know. I don't use the s pen very often.

Try switching from "adaptive display" to "oled cinema".

Switching to modes other than Adaptive Display just gives me seemingly the same shade of yellow....
I have tab s2 and you can't change adaptive display. I wouldn't have bought this tablet if I'd known about this issue. Very annoyed.
I actually have the issue on my Samsung Tab S2, that the colors are really "hard" and lots of color information are missing in the video, details are lost in dark areas. Is there some fix for this or is the screen just too bad on the Tab S2? I know the Tab S3 has a HDR screen, and the S2 not. I dont have any HDR screens actually, but I can put color range to "full" on my desktop PC, which will en-light colors a bit, making details more pop out in dark areas (though black isnt fully black anymore if so).
Any color profile other than basic is mostly unusable, too much saturation. Still dark areas lack lots of information. Is there no way to fix this? I tested this actually
https://phandroid.s3.amazonaws.com/wp-content/uploads/2016/03/Screenshot_20160321-154452-400x711.png
and it helps with the details in dark areas, but it also makes the black bars of movies in Netflix and video players not black anymore but gray.
So from what i can tell, it's only a stock rom problem. As the screen looks amazing running liniage (best screen in the house). But I've recently decided to go back to stock debloated, as I think its running a bit snappier than liniage 16 or 17.
Has anyone found a black level fix for stock yet? (preferably not a screen tint app)

:cyclops: It's beyond what you're suggesting which is known :cyclops: but thanks for it
EDIT: I have now found a full workaround. First you need to enable Blue Light Filter. Then go to Settings > Accessibility > Visibility enhancements > Color adjustment > Personalized color, and choose all the colors in the correct order. If you do it correctly there won't be any change to the colors and Blue Light Filter will be "on", but actually not, which will override whatever Android is doing that's making the dark parts of movies way darker than they should be. So far I haven't found any cons of this workaround.
Original post:
Sorry to resurrect an old thread, but after trying to fix this problem for like half a day (lol) I think I found the best workaround so far. If you turn on Blue Light Filter and set its opacity to minimum, the filter will be barely noticable, but the brightness issue will be fixed.
One thing I noticed is that not all apps have this problem. For example VLC, Youtube do have it (you can even see the transition of colors and brightness for a second when exiting to desktop view). However Youtube Vanced doesn't have this issue, so I asssume the operating system does this dumb change of colors when it sees certain parameters in an app (maybe something in the manifest.json file?). It would be awesome if some more knowledgeable people could look into this issue, maybe they could find something about why YT Vanced has normal colors.

Samsung S9 HDR playback bug?

Hi guys I just wanted to check if anyone else is having this issue whilst attempting to play HDR content with their S9 plus or S9. When I play a video on YouTube that's HDR compatible the display kind of mutes the colors and reverts back to photo mode during playback.. not the dynamic mode with vivid colors. Even if I have dynamic display selected and video enhancer on it still goes back to a washed out photo mode whilst HDR plays. Anyone else having this issue? Maybe samsung have gone with the more accurate colors during HDR now on purpose but I doubt it and it seems like a bug. I have the s9 plus exynos model. Cheers.

Yup me too on youtube...
Hope they'll fix this.
This is a common issue on Oreo, and you can fix it by setting the brightness to max. Haven't experienced it myself after the latest firmware update (ARC5).
It does not happen on my S9+. (U.S. unlocked)
Hopefully they fix this.. it comes and goes . Sometimes it's fine and others it reverts back to photo mode throughout the entire video.
Still not fix or acknowledgement from Samsung. Pretty poor. This a long with crap battery life and overheating it's not a great start.
Brightness sometimes fluctuates by itself while watching HDR videos on youtube on my SD845 S9+ which I can "fix" by turning brightness to max but otherwise HDR never shuts off for me. I have a feeling the exynos variant is the cause of a lot of problems as I keep hearing about crap battery life on Exynos versions too
I have the same issue, posted on Samsung Community on the day the phone arrived on the 9th March.
Didn't want to repeat what I said, also have images in one post to compare S8 to S9+.
https://eu.community.samsung.com/t5/Galaxy-S9-S9/S9-Mobile-HDR-not-enabled/td-p/441848
As of today still no fix or acknowledgment of the bug by Samsung..
Boxing it up and getting a refund tomorrow.
Do a hard reset after the update, now my SD845 S9+ works perfectly.
Yes my screen flickers when watching HDR video on auto brightness. When set to MAX it seems fine.

Question Videos are washed out in many apps such as Google Photos/Chrome

Hello all,
This has been an issue since I got the pixel 6 at launch. When playing videos, the shadows appear washed out. It appears to be some sort of gamma shift or HDR tone mapping issue. This happens when in google photos, chrome browser, imgur, even other apps. (youtube is fine).
I've confirmed in person this happens to other pixels one of which was pixel 6 pro.
The issue is recorded here:
I tried changing the color setup under display options in system settings, turning off H265 in camera settings, booting into safe mode, forcing 60hz refresh rate, but it still washes out the videos.
This does not happen with videos shot by other phones, for example my wife's iPhone shot video then sent it over to me and the gamma shift does not happen...
Strange thing is, in Chrome while playing the video, as soon as I swipe up from the bottom to open the recent apps, the video jumps back to normal as seen here:
https://imgur.com/a/Va3l5fQ
I reported this to google, and their chat support to me to fully nuke my phone to factory....
Does anyone have any idea why this is happening, and could other Pixel 6 users verify it's happening on their devices as well ?
Thank you

I seldom shoot video with phones and usually don't like to reference reviews. But from what you described Dxomark's summary about video performance is looking to be spot-on.
Google Pixel 6 Camera review: An outstanding performer in its segment - DXOMARK
The Google Pixel 6 camera displayed an outstanding performanc and is currently the best option for photographers who prefer smaller devices.
www.dxomark.com
My experience with dark objects in still photos has been somewhat similar. Recently I couldn't get enough detail photographing black camera bodies I'm selling online. Even with direct light from a daylight LED lamp I ended up using night mode. Every speck of dust showed up which wasn't ideal either.
Over all, though, I like the Pixel 6 camera.

Did you ever find an answer to this? I'm having the same issue... though it's not for every video, just in certain programs/websites.
Cheers.
I've been able to remedy this in chrome by turning off HW Overlays in Developer Options.
It's still an issue in Google Photos.

Sorry if I didin't understand it at first, the toggle to disable HW Overlays in the developer options will always turn off again, at least in Pixel 6, so that's what confused me

Huh it stays on on note 10 . In that case i am not shure how u can keep it on. Can u elaborate on when it turn itself off back again?
Weird, after I turn it on, I can go to any other screen on the phone, if I come back the toggle it´s off again, maybe it´s a bug on my end, here´s the example
