akshay, 22 Oct 2016not getting update of marshmallow on xperia c4try on Sony pc companion. so u Can do the update.. if the update directly comes to the phone, It depends on the reigns.. so u have to wait until it comes to ur phone.
I m frustrated with Sony after sales service. For a small problem they told us to replace the complete motherboard whereas in local market I got it repaired for 500 only. But after some time the same phone got the problem of display. Since the Sony parts are not available in market so I requested the Sony Service centre to repair the same. Even being Sony service centre, they were not stocking the Sony parts n told me to wait for 3 weeks. I purchased Sony handset for the first time and regretted my decision. I never trusted after sale service of Sony mobile service centre

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
