Thanks for reply
Yes I try from one year ago many wallpapers themes static or current wallpaper reset and...
Before I had iPhone 5s, I think Android is original blur lockscreen wallpaper but when searching for solution have found that's some people have clear lockscreen on stock launcher and some get blured that issue come from Android 4.2.1 and continued to 5 because lockscreen settings gone, and down to up on home screen hidden settings not work in every phone, I know next lockscreen or any custom home works fine but due to notification bugs prefers stock.
Muzei have blurness effect control but just work on home wallpaper.
I test so many wallpaper apps, Zedge Google wallpaper, wallpaper HD... Nothing😕
