The app HD wallpapers is a fake app. Aacording to its name, it would show HS wallpapers, but its not loke that.
I have tried the app and I found the app is fake
1) it have all old wallpapers. The wallpapers are old and I already have used them.
2) low pixels. The app says, I have all hd wallpapers but its not true, it have all low pixels wallpapers.
3) update never comes. The developers never provide any update, it means no new wallpapers will come
Over all its a waste of time,
DONT INSTALL.
