[OnePlus 3 & 3T Cross Device Development] Johannes1098:
Sounds very good. I'll try it as soon as a new build for our device gets released. The builds are still weekly (https://review.lineageos.org/c/LineageOS/hudson/+/277185/), so we have 6 days to wait (or they'll set back to nightlies earlier, but who knows..) Maybe the clock issue is also fixed until then..

Another issue I noticed today. I wanted to check the available accent colors in "designs and wallpaper" (ThemePicker.apk) as here started a discussion about the "pixel blue"

But the app crashed - I started it via Settings -- Display.

My launcher is Nova, so I switched back to Trebuchtet.

There, the app started. The tabs for Background, clock and grid layout worked. But selecting the Design tab: it crashed again.

I clean installed LOS 17.1 with the 0423 build.

Anyone else with a crash at "Design"?

Edit:

Ok, now I cleared the data and cache of the "Designs and wallpapers" app (ThemePicker.apk)

The Design tab started working again.

It said that my design is stock - but I changed the icons and accent color.

I tried to create a new "Custom" design. I applied it - this also worked.

But after, the app crashed again as I tried to open the Deisgn tab again..

I'll also create a logcat for this soon.. Seems like it doesn't want to read in my custom design profile..

NullpointerException

I'll compare it to a logcat when it's working (after clearing data of this app ANd before applying a custom theme)

I cannot say if it had worked before. I set my theme once when I installed LOS 17.1 the first time. And then never opened Designs and Themes again (till this day..)
