I looked on amazon and found a spigen ez fit for the mini that has full edge to edge without the notch cutout. take a look at this link, do you think its a legit product? no reviews at all or anything. https://www.amazon.com/Spigen-Tempered-Protector-Glas-tR-Deisgned/dp/B08DQDHR2S/ref=sr_1_25?dchild=1&keywords=spigen+iphone+12+mini&qid=1604885878&sr=8-25
listed as "sensor protection" meaning it covers the notch. never seen this by spigen before. i hope its real lol
