I recently updated my samsung A72 and after the update I am not able to use smart launcher 6....It says the alpha version of smart launcher is outdated....doesn't install on my mobile...pls look into it.... The problem stated above is partly solved....But now I have lost all my settings....I don't know how to get back to my earlier look and feel of a circular setting of all icons in SL3 theme..... Why did they have to do the update without backing up my old settings....
