You can also try Camera MX, it works faster than Open Camer I think.

I use ROMs metioned here http://bbs.blackview.hk/viewtopic.php?f=192&t=319505#p529668 But as Pappmann wrote, there is an issue with switching users. That's the reason why I'm asking for SystemUI from BV6000. I have decompiled apk and found settings, but want to compare with BV6000 SystemUI to fi...

Might be confusing

The rom downloaded miss the Checksum.ini that assure the integrity of the download, so SP Flash tools don't allow you to continue to the next step.

You probably mean SPMD tool not SP Flash.

I agree with request to have option to save photos on SD.

Actually only way is to change settings but everything will be slower. Read/Write speeds are slower.

I had no issue using SP Flash Tools.

Can you share BV6000 SystemUI.apk?

I can confirm the issue. BV 8000 Pro colors are far away from reality.

I'm running alternative ROM + root and just added two lines to build.prop:
fw.show_multiuserui=1
fw.max_users=3

I believe Blackview can do this too for us in the next ROM release
