I got the Huawei P30. I'm also completely satisfied.
But now a first problem. When I stream Netflix on the phone, the picture is much darker than normal. I do not have this problem with my business mobile phone (iPhone).
Youtube or other videos are no problem in terms of brightness. But with the P30, I can't stream videos that day. The picture is too dark.
Can someone help me there? I have not found anything. Will only be reported on "black screens". Mine is not black but just very dark.
I'm not sure if this has anything to do with it, but it could be that the screen in the app is automatically dimmed. Should probably occur in Huawei and Honor: https://www.appoid.de/news-infos-rund-um-android/loesung-huawei-honor-verdunkelt-dimmt-automatisch-das-display-in-einigen-apps/
You could also turn off the automatic brightness adjustment, if you have turned it on, set your device to maximum brightness and see if it gets better.
