Double Tap Wake, is it possible?

[k44]

Hi, I'm new XZ2 user. This is my 1st Sony phone, well, 2nd after Sony Ericsson k550i:)

I just want to say, that if fingerprint scanner is on the back, the only option to fast unlock phone without grab it is double tap wake. I had it in LG or OnePlus...

And I really miss it.

Is there any chance to implement double tap wake on XZ2?

Sorry, I'm more or less certain it won't be available on your device.

I just now bought an XZ2 and it doesn't have tap to wake or sleep. My Xperia X had both.
