Additional Features

The BLU J4 comes with an FM radio and supports a microUSB 2.0 interface for charging and data transfer. While it lacks modern connectivity options like NFC, it retains a 3.5mm headphone jack, which is a welcome feature for users who prefer traditional headphones or have accessories that require it. An accelerometer sensor is present to support orientation-based functions typical in smartphones.
