Mark Gurman, reporting for Bloomberg:

The control feature would let iPhone users perform some tasks by moving their finger close to the screen without actually tapping it. The technology likely won’t be ready for consumers for at least two years, if Apple chooses to go forward with it, a person familiar with the work said […]

We know various Samsung phones from the past had this feature, but apart from a few people who liked it in specific scenarios, it wasn’t generally well-received.

Apple is also developing iPhone displays that curve inward gradually from top to bottom, one of the people familiar with the situation said.

I recall having reviewed the Google/Samsung Nexus S back in 2011 and I was completely indifferent as to whether the screen was curved or not. I do however greatly enjoy the delicate edge-curves on the iPhone 6 and newer series iPhones, including the iPhone X — this is preferable — while, at the same time, the Galaxy S8 and S9 screens are curved way too much, making accidental touches a daily ritual.
