Saving camera images/videos to SD card works fine but gallery app cant show them until you reboot ( for pros: mediascanner service runs only once during boot. Global AOSP issue )

Awesome! Happy to see 10 on our old Girls. Only 1 question before I start downloading. Does this rom have a navigation bar? I killed all 3 hardware buttons a long time ago and so I can only flash ROMs that have the navbar option.
THX a lot to you, Buff and the whole team

This isn't work properly. Sourceforge as opengapps websites don't have these gapps what we need.

Great job?!! I'm using since yesterday and, some troubles like buttton delay, consume some battery at first time, and needed a full clean install to work. But so smooth, it's like a better vision about the screen, sound is better and fast. Testing battery consume now. Thx side and jdc team!
