According to evleaks, the Samsung Galaxy Axiom (SCH-R830) will offer a 4 inch WVGA display, similar to the Samsung Galaxy S III mini. The processor on the Samsung Galaxy Axiom is a dual-core 1.2GHz Qualcomm Snapdragon S4 versus a dual-core 1GHz NovaThor processor on the Samsung Galaxy S III mini. Both models are equipped with 1GB of RAM and a 5MP rear-facing camera. The tweet suggests that the Samsung Galaxy Axiom will have a 1.3MP front-facing shooter vs, the .3MP camera on the 'mini'. The latter comes with Android 4.1.1 out of the box while the Samsung Galaxy Axiom will have Android 4.0 installed. Lastly, the Galaxy Axiom offers LTE connectivity, something lacking on the Galaxy S III mini.
Evleaks says that the Samsung Galaxy Axiom is heading to regional operator U.S.Cellular, which would seem to be a perfect place for a niche device like this. The tweet had no information on expected pricing or availability.
