Phones don't need built-in physical controls. Attachable controls like the Nintendo Switch Joy-cons have been becoming more popular as phones have replaced handheld gaming system for the majority of people. The new Razer Kishi looks good though my phone is too big to fit it. ASUS ROG and Xiaomi Black Shark gaming phones also have their own official controllers. A new handheld will probably not be able to succeed without software. That's what killed Windows Phone.
