Well, that was quick. It's April 1, and Samsung has already started rolling out the security patch for the month. The update - arriving as build number J320FXXU0AQC3 - is currently hitting Galaxy J3 (2016) units in Europe.
Some regular bug fixes as well as device optimizations are included as well.
As is usually the case with OTA roll outs, it might take time for the update to hit your device. Meanwhile, if you feel impatient, you can manually check for the update by heading to your handset's Settings menu.
Why don't just roll out android m update for j3 (2016)?
So... EU J3 2016 still doesn't have android 6.0... Not funny 1st april joke.
I'm very disappointed in both Samsung and Google. Samsung's software update in December last yr is why my Galaxy 5 is messed up. The speakerphone,volume control&everything associated with it stopped working. I've tried unsuccessfully several time...
