My 1st 4 replacement digitizers were for ipad 5’s . None of them workedand the air one screen had a replacement home button ordered for a ipad 5 . So NO your conclusion is not right. I’m thinking either something is wrong on the board from the damaged original home button or some other reset needs to be done I’ve seen in a video but forgot to try when the new screen was on. I do have two buttons coming from ifixit and will try one of them. Thanks for your experince in what’s worked for you but as usual everything i get seems to be outside the norm. I’ll wait and see. Just wondering if all the parts I’m getting are just bad ?
