It's crap technology that can be fooled with a photo. Not working in the dark is a failure. It's garbage like so many other Samsung "innovations."
Again, FIRST does not matter. Just ask Microsoft and Palm. Apple got rid of the home button for a superior form factor and experience. I LOVE not having a home button. Swipe up is so much more natural. I love the new design. I love FaceID. Many others agree and will agree once the technology starts taking hold. It will only get better.
There would not have been an iPhone without the success of the Palm and PocketPC. First DOES matter sometimes. By the way, FaceID can be fooled too, though its a little harder. Does that make it "garbage" because it doesn't work perfectly every time?
But Apple sure did copy their own share of things, like offering big and different size phones, wireless charging, waterproofing and facial ID. I mean, Apple refined some of these features, good for them. But don't forget, Samsung makes a lot of Apple's parts. That's no small contribution.
So I really don't know why Apple fanboys hate Samsung so much. I like when companies copy each other, That means we get better products that are non-exclusive to one kind of phone.
