Are you certain that double-tap to wake up its on the C4 dual?

[kragoth]

No i cant found this feature but this feature is on lollipop
And implemented on some device sony like Z3+

@kragoth

Indeed, this feature its not available on all Xperias, the Xperia Z and Z1 lack this feature, even if they are flagships. With that said, there are third party apps that you can use

Big difference between C series and Z series..
If it is there, it's in settings, display. And at the bottom

No this feature is on lollipop google android.
On cyanogenmod rom
On some aosp rom.

@kragoth

You can contact your Local support but not all of this features are available, an example, the Xperia T2 Ultra doesn't support multiple users on lollipop, why? not enough RAM 

[Lord_viridis]

And that's to do with Sony ui how?
For whatever reason, it's not present on some models, even other manufacturers flagships don't all have this feature.
Aosp does not mean the stock fw will include features present in the Aosp.

I know xperia c4 is mid range flagship but with test and benchmark equaled with high range i had 45000 with antutu benchmark.
I think that score is for high or Z serie xperia.

@kragoth

neither the Xperia Z nor the Z1 have this feature
