I've reviewed Android foldables for years. The iPhone Ultra needs these 5 things to succeed

The world's first commercially available folding phone was the Royole FlexPai, and I still distinctly remember using it at CES 2019, thinking to myself, "There's no way anyone's buying this." And, probably nobody did. But that product lit the spark for companies like Samsung and HUAWEI to take up the challenge and lead us to where we are today with foldables.
