Well, I feel the headline is as straight forward as can be, but ill be more specific. I purchased my Lenovo Legion Duel 2. So far I like the phone, but I cant seem to get Nova launcher to stay the default launcher. I manually downloaded the play store on the phone, not sure if I did it properly, I downloaded Nova, made it tho default home but, it doesnt stay. If I swipe up it goes back to zui, if I dont touch my phone for awhile when I go back into it, it reverts back to zui. Does anyone have any ideas on what to do?
