    I have read the threads surrounding the black crush display issue and have been wondering if everyone with a OnePlus 7T Pro is experiencing this issue or if it's just specific users. I've been told it's a software issue, however, if only specific users are experiencing it, then isn't it a hardware issue? I would've expected this issue to be far bigger of a topic than what it currently is right now, however, it seems not many are speaking about it, making me further question whether it's actually software.

    I've seen users suggest using screen balance to temporarily resolve the issue, however, I do not want to install that application for security and privacy reasons. Also, I just received the OnePlus update a few days ago which hasn't resolved the issue at all, so if screen balance could 'fix' the issue, then so could OnePlus. I'm from the UK so there isn't a OnePlus store for me to go to. This issue has been going on for a fair amount of time and I'm beginning to lose hope in OnePlus.


    Just to add, I have tried using DC Dimming, but I found that to just make things worse. Also, if the issue can be resolved in a software update, any date range on when this update can be expected because right now I have no idea if it'll be the next update, or in an update a few years down the line.

    Many are, but everybody is creating their own thread which dilutes the discussion.

    If you had already read threads about it, you should have continued discussion in the most active one of them.
    There is no need to create a new thread about it.

    Those threads aren't recieving much replies or new information. The OnePlus team seems to be fairly quiet with the issue, and as I've mentioned in my edit, no ETA has been given on when this issue is expected to be resolved, if it is truly a software issue.

    Exactly because of the issue I mentioned. Everybody creates their own thread just like you did. So how will any conversation or discussion sustain?
    Because instead of providing feedback and bug reports, people only create threads here. This is a user forum. You interact most with fellow users. Only if a thread captures traction and many people interact in one thread, no thread comes under the focus of company.
    Same as above. Unless they get multiple bug reports and feedback, why would they even think about it?

    I've spoken to their support and given them feedback. However, I've just been told to wait for a software update with no ETA. I see many threads on overheating/battery issues, however, I see far less threads/comments on the black crush issue, making me doubt it's software that needs fixing. What I truly wanna know is whether this issue is software or hardware, cause I don't want to wait for a software update that never arrives, or a phone/screen replacement that faces the same issues.

    Seeing that two people voted in the poll that their devices haven't been affected by the black crush issue, I'm starting to get worried that this could be a hardware issue, unless those two users aren't sure of what black crush is or they haven't updated their devices for some time.

    Not everyone uses their phone on lowest brightness... guess that could be one reason for the votes, they don't see it

    The issue is that I can also see the black crush when on the max level of brightness.

    I only have it on lowest brightness at night on my device

    at the maximum brightness you can not see it only if you take a closer look, but if you scenes where there is a black crush and then makes the brightness higher, it is still there

    I know what the black crush is, I often use the phone with almost minimal brightness and it's still ok even in the darkest scenes.
    And yeah, I'm staying on 10.0.7 to avoid surprises. Everything works alright, great battery, why to change

    I think this is a big problem. Shadows are always pixelated. Not only on videos but also on photos. You can fix it a bit with an app called screen balance. set it up to fluorescent(warm) and strength to 60%. Try it out. So I think that is a software Issue.

    OnePlus customer support have suggested flashing my device to solve the issue. Has anyone tried this, and did it make a difference?

    Flashing in this case is basically re-installing the Oxygen OS. Everything is erased from the device during this process, so you need to make a backup of your stuff first. According to Customer Support, they'll do this for you remotely, and they claim it fixes the black crush display issue. I just wanna know if anyone's tried this and if it worked.

    Alright, I've just realised something. If I am playing a HDR Video on YouTube in a browser app (Chrome, Firefox, etc), black crush is displayed, however, if I play the same HDR Video on the YouTube app, no black crush is displayed and the colours are all fine. So this means that HDR content isn't affected by the black crush, but non-HDR content is affected.

    Here's a video you can use to test this yourself. Play it in the Google Chrome app, and then play it in the YouTube app to see the difference.

    HDR works on YouTube without any kind of black pixels
