Display "black crush" issue - ZTE Axon 7 Guides, News, & Discussion

I got a new warranty replacement and just noticed it has "black clipping/crush". Not sure if it's something I never checked to notice before but this replacement display is a little strange too.
Anyway if some people could please check the attached image to see if their display can show the lowest level of black 1. I took the image from an old Note thread. I can only see as low as 6 in Chrome and 3 in Quickpic. Brightness needs to be around at least 50% to allow the lower range to be visible.
If this is a normal issue then it's likely a fault fixable in kernel. I know my last AMOLED a GS3 had this fixed by custom kernel, seems it was a mdnie driver fault https://github.com/AndreiLux/Perseus-S3/commit/9a8a38667bb081fa83c583ef12ad81d7df359066 Don't know if that can apply to us but if it's confirmed a fault I'll look for more recent information. Thanks

With my phone I can see only until level 5 with maximum light but I can guess the number 4 and the lines until the lowest level.

The numbers should be visible down to 1 when working properly. I've seen it fixed before on the old GS3. Each step down is a gradual step down shade darker. With black clipping there's a sudden drop to black after a particular number.

My screen works fine. Perhaps it comes from the picture.
You should try Display tester to check your screen.

Display Tester app is where I first noticed it with the similar test under Black saturation. If it's just my device it could be a hardware fault or ROM/Kernel setup. I'm on RR-O with Hellsgate Kernel 3. This current display does have a bad off tint spreading from the bottom right corner. Need more samples to narrow the issue down.

I talked to a dev about this and he had no idea what i was talking about ? let's hope someone sees this and cares about it
I'm seeing 3 with the latest AEX and full brightness on XDA Labs

Still need samples to narrow the issue. Just searched and found this "Pixel 2 XL vs Samsung S7 edge Black Crush Test at max brightness". So 3 isn't so bad compared to the latest greatest Pixel at 9, but that's LG's first generation P-OLED for you. More relevant is the S7E has our same display down to 1 so the display's evidently capable, just incorrectly set somewhere. Interestingly it's also easy to find complaints of GS8 and GS9 series black crush/gradient banding issues

Looked up if there's a fix out for the newer Galaxies and it seems not from recent GS9+ discussion. Custom developer work on Samsung display mdnie hasn't progressed in a few generations https://forum.xda-developers.com/showpost.php?p=76532055&postcount=721. I guess it is what it is, at least it's not as bad as some of those recent flagships, those complaints on the GS9+ thread about gradient banding sound terrible and apparently some update improved that but worsened black crush at the same time.

Haha similar, using XDA Free on 50% brightness I can see until 3
EDIT: ok tried with max brightness(auto brightness off) and can confirm still 3 so I guess that's as good as we get xP

How about official N and O stock? Could it be an AOSP fault?

No, it's normal on every friggin build i tried. I guess it should be possible to fix this with files from the S7E/Pixel XL?

You completely sure? It's known to be pretty bad

You know I don't have a very good sight anymore. So, for me the screen is pretty good.
OK I've tried again tonight, and with full luminosity I clearly see until 4 and I can guess the shape of the 3.

well, that's the problem. If you watch some video or movie with much black, you'll see this in a lot of places, it's like you see black where there should be gray and it's really unsettling tbh

Ok, I've understood.

I am very curious to have the black crush resolved also. I played with all the settings on KCal and none really helped

Been watching more videos on my A7 now and decided to revisit this old dead topic. I found similar to other devices discussion on the issue you can workaround a fix using an overlay app called Screen Balance. Using this my cinematic viewing experience is heavily improved in very dark scenes. https://play.google.com/store/apps/details?id=co.uk.quickdoc.screenbalance
As our panel works apparently in the S7E/PXL and for us is only slightly lacking we only need to apply a little fix. Raising "strength" gamma in the app just enough that 1 on the chart shows works well. The free version with fluorescent (neutral no change) balance and 10% strength works on two tested A7's. If going paid pro you can have run on boot and tint/rgb mode that require 3/1% strength respectively instead. The other modes aren't visibly different and aren't necessary to this workaround fix. Hope you enjoy this fix three years after the phone's release
extra note: I watch content at 80% brightness when focusing on fidelity and that's what I tested by

note the overlay leaves scrolling laggy unless you enable Disable HW overlays in Developer Settings.

Making the changes you describe crushes whites unfortunately, so whilst shadow detail is preserved, whites are not. May just be by aging display of course.

[Q] is there any way to increase the saturation of the colours?

had a google and found a reference to some firmware update that came out a month or so ago but mine is up to date apparently and i see no option for colour saturation

Simply because there is no options to do so. Sony advertise and work on true color and not saturated colors. So maybe there will be some mods on upcoming kernels, but as it is now, colors are really good.

Android wear 1.4 (6.0.1) update really makes the watch much smoother on my WI502Q

Apart from speaker support (502Q model does not have one), new 6.0.1 update brings lots of performance improvement over last 5.1.1 firmware. It does not unlock extra cores of cpu or boost clock or anything, but overall smoothness makes everything function better already.
It used to lag, freeze, miss my input attempt or even drop my swipe action and press random places where I did not intent to press. They are almost gone. I am not saying it is smooth as butter, but input mechanism and performance improvement is really visible.
Apart from that, nothing really changes in functional perspective. Little minor tweaks here and there, and that is it.
But I'm very happy indeed to have 6.0.1 on this watch and finally it is a pleasantly useful device to have on my wrist.
Good job, Google. Bad job Asus, not putting a speaker on smaller variant without mentioning it.
+ I didn't have a chance to test call control functions which did not work properly before on my Galaxy S5.
The same on my smartphone, MM running much better than LP.
I would be suprised if its different on the watch...
Sounds great. Quick question: does the Always On screen Option is still available?

It's been rolling out for almost two days. But only for smaller variant WI502Q. Many of the users with WI502Q should have it by now. Hope there won't be too much delay for WI501Q update.

Scratch that! I got mine Friday... Battery life is freakishly better... Mine was charged Friday morning. Battery ran out Sunday afternoon with ambient mode on full time! Speaker is OK (not gonna use it so really don't care lol). Finner controls over permissions and DND mode was a good one too!
Enviado de meu XT1097 usando Tapatalk
Looks to me that it's smoother because they slowed down the animations. Still takes a while to move around the menus, it just doesn't look as bad.
I get the same battery life as before. Ambient mode on, minimal FaceDesigner custom face. 100% in the morning, ends up at ~60% at bedtime.
Sorry misread, thought 1.6 (6.0.1 threw me off)
Is there a plan to make voice a two thing? It would be great if Google Now could respond in voice like on the phone. If it is currently possible to have a two way phone conversation, would it take much to get Google Now to do the same? Would be great or is this a thing that will be way in the future?
Hi!
From today I'm owner of ZenWatch WI502Q. I notice that you are talking here about ambient mode but 502Q model doesn't have ambient light sensor. How can you turn it on? There is no option for turning it on and I'm running latest update.

Note 9 Camera AI port

Hi there. Just would like to know your opinion...The Note 9 has the same camera as the S9+ with one key difference, the AI that automatically adjusts the camera to the correct scene mode(eg. taking a picture of food, automatically switches to food mode). My question is, will the S9+ perhaps get an update to have the same AI feature or will we need someone to port the camera from the Note 9?

Don't think so. AI Camera is the only difference between S9+ and N9 except SPen. So...
I hope an update will do the trick....otherwise I hope for the clever people to port the camera app
There is a discussion about this https://forum.xda-developers.com/ga...iscussion-note9-ai-photography-to-s9-t3827193
But my personal opinion is that we won't get it. Note must be something more than S9+ so... The reason also that we did get android 8.1 was because they keeping it for Note.

For my taste the most stable version is 1.3.1-18_07_11_0926_15
I can't begin to express how much I love this browsers. It is fast, really really fast, like puffin fast. I don't know what you did but its too damn good. I have struggled to get a good browsers which linkoffers the perfect blend of speed adblocking and ui and kiwi provides just that. It didn't took 10 min to make me fall in love with it. The adblocking works as charm. I do have adaway for ads but the cosmetic filtering is what i wanted for ages. Really keep up the good work.

Video Issue: The Red Tint & Stutter Thread

Let's get a thread started to discuss the problems, and hopefully SOLUTIONS for two specific issues reported in many early release Huawei P30 Pro's.
First is a very noticeable RED TINT to the video produced on the P30 Pro and the second is STUTTER & LAG (seen mostly while panning).
Do you have this problem or is your phone fine? Do third party apps solve the issue? Is the issue software or hardware? Do recent updates solve the problem? Could this simply be an issue with pre-release software in some early videos?
Let's discuss & troubleshoot.
We need video samples (good or bad) from real people with the phone!!

Hopefully someone can provide a 4K video recorded with Open Camera set at max bitrate, with panning and moving objects.
Stumbled upon another fairly honest clip which does mention these problems, but also clearly notes things look lot less saturated when recording with wide lens
https://www.youtube.com/watch?v=eP6LtcH8724&feature=youtu.be&t=336
For comparison, here are bitrates from S10:
With the H.264 codec, the [email protected] videos are captured at 72Mbps bitrate, the [email protected] - 48Mbps, the [email protected] - 28Mbps, and the [email protected] - 14Mbps.

I saw that as well. The wide angle does not seem to suffer the same oversaturated picture. Does that mean it's hardware? I assumed this is probably software related. If it's software then third party apps could be a solution.

I would really like to see some video samples from someone on the .124 update. A lot of the video we are seeing from Paris is pre-release software. If someone can post some video panning and of people, to see if the red skin tones exist it would be great.

Hmmm, this 4K video does not look that bad. It's from a Croatian review site, which is usually pretty honest in their reviews. Yes, there is some jerkiness and saturation, but it does not look horrible. I'm leaning towards this being more of a software issue.

This also looks better (not great, but better) than TechTablets video test. Perhaps it's the new update?

Too bad he didn't upload 1440p or 4K. He has few other videos there as well, not bad, not great, image stabilization seems a bit shaky sometimes.

His other videos are nice, this shows 5x video, I like it: https://www.youtube.com/watch?v=yotUrvKQR4M
Sadly everything is 1080p again with lots of youtube overcompression. Interestingly he also has a lot of S10+ samples of the same locations.
EDIT: he has a few S10+ 4K videos there but none for P30 Pro.

The image shakes every now and then, kind of wobbles like some kind of distortion, it's probably software issue with image stabilization and also colors seem way off, like everything was red: https://www.youtube.com/watch?v=FA3fcyG9j6M

I am hoping that some people with the .124 update can check on their color accuracy. It's possible that the update included fixes - it would explain why some seem to be unaware of the issue entirely.
Sent from my SM-G975U1 using Tapatalk
I am also planning on using FiLMiC Pro since I can manually edit the saturation, red level etc. I understand it's not for everyone because it costs about $30 to get all the options but I'm interested to see of that gives me a 'work around' on some of the video issues. When I get my P30 Pro next week I'll be sure to update. Hopefully there will be a solution from Huawei by then and a professional video app will not be needed to produce great shots!
Sent from my SM-G975U1 using Tapatalk
Update: I have had several people report that their video quality is "excellent" and does not exhibit the issues we have been discussing. Perhaps the .124 update was a solution? It would be nice if Huawei (or anyone for that matter) would detail what specific improvements are contained in their updates. You would think they would want to disseminate the information to the public as fast as possible!
Can someone with the .124 update tell us if the issue is resolved?
Sent from my SM-G975U1 using Tapatalk
We need to see examples, some people will never see the problem in the first place. You won't believe me but I have friends who can not tell a difference between 720p and 1080p, when it's obvious to you, frustrating...
There's no red tint on 124. None that i notice anyways. When does it occur ? Indoors, at night, all the time ? Panning has some slight stutters at times if you move it too fast. Feels like the stabilization can't keep up with the horizontal swivel.

Yes. I can see it in the steps immediately. Are you showing the difference between phones with the .124 update and prior to the update? Or are you showing us two different phones on the same software? What is different, because that pretty well suggests a fix.

Different phones but same location same time, to make it easier for testers to spot red tint, show what it looks like compared to no-tint video.
I do not know if the tinted video is before or after firmware update.
I think red tint goes away when he zooms in 5x.

Oh damn. I thought you fixed it on the P30 Pro. What other phone was used? S10?
Yes the issue will not be on the other lenses. It's a problem with the main camera. My guess is the RYYB turns out to be a bad match to the way Huawei has the saturation - specifically red levels pre-set. So a 3rd party video camera app may solve if it allows me to adjust. This would be an easy fix for Huawei if they pushed an update that turns down saturation, but it don't know if they can do that for only one camera?

Yes red tint will go away if you use the wide or telephoto lens cause they use different sensors,but the problem is with the spectrum sensor that Huawei decided to ditch the green pixels for a yellow one that's why the red tint occur.
