kailash, 09 Oct 2016No security update since 1 july 2016. All others have dispatched for september too.
Not only on C4s, my Z5P is still security patch of April 2016.
This is due to SONY lazy to rollout security patches. Very bad
Finally upgraded my parents' two C4 Dual. They're now more smooth (at least no more lag while doing the same processes). Also seems longer battery life (I tested play the same several video files and watch the same YouTube videos via wifi).
It is amazing that the camera shutter delay now is shorter, means respond faster. However, photo saving to microSD takes longer. Also, the photos taken by 6.0 are more sharp (could be due to shorten the shutter delay) and more vivid. Now, the colours of photo and the real looks the same. When 5.0, most photos look a bit grey.
Thanks to SONY

AnonD-543209, 02 Oct 2016Hahahaha Don't buy Sony is stop making Xperia c4 and C5 Go to xa or xa ultra Dude i m using c4 since year.. Excellent phone no doubt. Sm days ago screen ws misbehaving n not responding, gave to Sony care. They replaced whole front of my c4 in less than 24 hours. Didn't charge single penny coz I was having bill n warranty. Just keep bill n warranty n u r safe! Don't create unnecessary hype.
