Performance
Running on Android 4.1 Jelly Bean, the BLU Studio 5.3 II is powered by a Mediatek MT6577 chip with a dual-core 1.0 GHz Cortex-A9 processor. This setup, along with 512 MB of RAM, provides adequate performance for everyday tasks such as calling, texting, and web browsing. However, the limited RAM capacity and dated processing unit could struggle with more demanding applications or multitasking, which is a common limitation for smartphones in its price category from that time.
