Miami-based smartphone manufacturer BLU has recently started pushing out a new update to its Life One X (2016) smartphone. Weighing in at around 1.3GB, the update bumps the Android version from Lollipop to Marshmallow (6.0). No other changes are included in the update - at least that's what the official change-log says. The roll out commenced a couple of weeks ago, but if your unit hasn't got the update yet, you can manually check for it by heading to your handset's Settings menu. Via
