Performance
Under the hood, the Sync 4.0 is powered by a Mediatek MT6572M chipset with a dual-core 1.2 GHz Cortex-A7 processor, paired with a Mali-400 GPU. Running on Android 4.4 KitKat, its specifications align with the basic smartphone performance expectations of the time. It provides a generally smooth experience for light tasks such as calling, texting, and using social media applications, although it struggles with more demanding apps or multitasking due to its limited 256MB RAM and 512MB internal storage, which can be expanded via a microSDHC card.
