Performance
Under the hood, the BLU Advance 4.0 L3 is powered by a quad-core 1.2 GHz processor paired with a Mali-400 GPU, providing adequate processing power for routine tasks such as calling, texting, and light app usage. Running on Android 6.0 Marshmallow, it offers a reasonable, although outdated, user interface for users used to simple smartphone operations. The device comes with 512MB of RAM and 4GB of internal storage, expandable via microSDXC, which suggests that multitasking and app storage are significantly limited by contemporary standards.
