Hi, all and @ThommmF
. All those permission are needed because of Muzei Live Wallpaper and for loading Wallpapers. There are no wallpaper as for now but will be added on next update. Almost all Icon Pack and every new generation icon pack uses all those permissions. New generation icon pack like - Minty, Splendid, CandyCons, Moxy, Adora UI, Circa, Cornie, Ango, Aivy, PixBit, Squared, Nadeon etc. You can check other icon pack app's permissions on Google Play Store. So, Please don't give any bad reviews for this reasons.
Hope you all Understand me. Happy New Year! Have a nice Day!
