The new U.K.-based scheme is fairly straightforward. If you want to trade in your phone (it will only accept Galaxy S and Galaxy Z models at this time) without buying a new handset, you can do it through this portal. Samsung will then gift you store credit that lasts for up to five years and be used to buy anything Samsung sells.

The Galaxy Z Fold7 has more impressive design changes—now incredibly thin and lightweight. You will spend most of your time on the outer screen, which means the thinner frame really helps with one-handed use, and the wider 6.5-inch display means it's easier to type.
