Performance
Under the hood, the Maxwest Astro JR runs on Android 4.2.2 (Jelly Bean), powered by a Mediatek MT6572M chipset. The dual-core 1.0 GHz Cortex-A7 CPU paired with a Mali-400 GPU presents a basic performance framework. With just 256MB of RAM and 512MB internal storage, the phone is better suited for minimalist applications and occasional app use. The expandable storage via microSDHC offers some relief for users needing additional space for media and other files.
