Display and Interface
The device features a modest 2.8-inch TFT LCD screen with a resolution of 240 x 320 pixels, translating to a pixel density of about 143 ppi. While this screen may not compete with modern smartphones in terms of size and clarity, it offers enough functionality for displaying essential information such as text messages, call logs, and basic apps suitable for outdoor viewing in bright conditions. The Sonim OS, based on Android AOSP 11, is designed to be straightforward and accessible, further enhancing usability in work environments where simplicity is critical.
