Performance
Operating on Android 4.1.2 Jelly Bean, the BLU Studio 5.3 S runs on a Qualcomm MSM8225Q Snapdragon S4 Play chipset. Its quad-core 1.2 GHz Cortex-A5 CPU combined with an Adreno 203 GPU was adequate for basic applications and tasks at the time of release, though it would struggle with more demanding modern applications. The phone's 1GB RAM and 4GB internal storage, which can be expanded via a microSDHC slot, limits multitasking and storage of larger apps and media files but is fair for its price range.
