As you probably know, 5G technology is brand new and still evolving and getting better every day. In order to get full 5G speeds, you need a direct line-of-sight to the cell tower or nothing in the way of the signal to get the fastest speeds as possible.
As a result, the popular case brand Incipio has an all-new case called the Tran5form that's built for 5G using a special new material. We're not sure if it's marketing jargon or not, but we trust and love their past cases.
The Incipio Tran5form uses a new 5G compatible and unrestricted smart material to cover the phone with some added durability. It's likely some different blend of TPU and polycarbonate plastic, but with an emphasis on not messing with the signal.
Otherwise, it's a good looking case that promises 5ft drop protection for your Galaxy S10 5G.
