Definitely, and in my experience, it’s a refreshing real-world testbed for minimal UX flows. I’ve used the Cat S22 Flip as a test device for a lightweight app designed for low-end Android devices. It’s an excellent choice from both a UX and performance testing perspective with its small screen, limited processing power, and the lack of unnecessary distractions, it really forces you to design around clarity, essential navigation, and accessibility. These are elements we often overlook when testing on flagship phones that have more power and flash.
What I also appreciate about the S22 Flip is the Android base. It allows me to run automation scripts and logcat monitoring without the need to root or hack the device. If your focus is on clean UI/UX or progressive enhancement in constrained environments, this phone is a gem.
