T-Mobile has started selling the CAT S22 Flip, a unique phone that blurs the line between smartphone and flip phone. The S22 Flip has the size and design of a typical rugged flip phone, but its 2.8-inch main display is a touch screen that provides access to the full Android interface, including third-party Android apps. Several other basic phones on the market leverage the open-source version of Android (AOSP) but rework the interface to operate without a touch screen, which makes them incompatible with the third-party apps available in the Play Store. By including a touch screen, the S22 Flip is able to keep the Play Store and access to most Android apps. As a smartphone, the specs are basic, including Android 11 Go Edition, a Qualcomm Snapdragon 215 processor, and 2 GB of RAM. Other specs include a 2,000 mAh battery, VGA screen resolution (480 x 640 pixels), 5 megapixel main camera, 2 megapixel selfie camera, a memory card slot, and an outer display. Like all CAT phones, it has a rugged design, rated IP68, water-proof, washable, drop-proof, and Non-Incendive Class I Division 2 Group A-D T4. It has "extra loud speakers", large buttons, and a programmable PTT button on the side. It comes with a 2-year warranty. T-Mobile is selling the phone now for $234.
