(Optional) Anything else you want to share?

I'm not sure if it is due to my wallpaper, which is half black and half white (it changes each time the phone is unlocked). If so, please provide an option to manually set the color

Research

• I have checked the manual and the FAQ and could not find a solution to my issue
• (Optional) I have confirmed the issue is not resolved in the latest alpha release (instructions)

@xenonnn4w FYI

@altius4444 Thanks! Is this a new issue in 2.21?

[altius4444]

Yep, I had no issues in the previous version. AnkiDroid just got updated and the widget changed colors

Could I get a video of that?

The portion of the screen that is black and the portion that is white changes each unlock

Edit: BTW, I can confirm that the widgets follow the wallpaper colors. I'm using MIUI too.

That's weird. I just put a different wallpaper (pure black) and then another (black and blue) yet the widget remained white. I tried removing it and adding the widget too after changing the wallpaper

[ZornHadNoChoice]

Oh, I thought your phone uses MIUI. Maybe it's a different problem then.

[altius4444]

My phone uses NothingOS. Not MiUI.

I just checked it with a phone that's on RealmeUI (Android 10) and the widgets become purple there, but do not change colors when I change the wallpaper and put the widgets again

Also, in case it wasn't apparent, the issue is for all widgets, not the deck picker one only

@david-allison @xenonnn4w
I found the cause of the issue now. When I changed my wallpaper the system automatically changed my system colors (?) to monochrome, with white being used for accents. Anki's widgets picked up on that and changed the color to white too, though none of my other widgets changed colors

There doesn't seem to be any way to tune the system colors other than selecting from what options are given. It'd be great if Anki could let us change the color of the widgets

However, even after reverting to an old wallpaper with which the widgets looked normal, and resetting to previously used colors, it still looks different

Previously, it used to be pure black (following Anki's theme)
