Hi 😉
After upgrade to V20, I found a bug that was present on V10, and had been fixed on V11 and V12. Now, is back :icon4:
Try to take a photo.
After, set as wallpaper.
Go to your standby screen and look at the photo. It is stretched 😡
On V12, the wallpaper was resized automatically and the photo sides were ''cutted'' to show the right wallpaper proportions!
