That would be awesome to see. No home/FP button but a small part of the screen that can be both. I don't why Samsung can't make the capacitive button switchable now. It can't be that hard a thing to do. Most other vendors like Huawei will let you switch the software buttons in any order you want them to be in.
Yep. Samsung should not be afraid to ditch the physical home button. Hopefully they're planning something for the Note 6, or at the latest, the S8.
