There is a thin metal frame surrounding the Xperia Z3 Tablet Compact and while it looks very similar to the Xperia Z2 Tablet, the new device takes a few style tips from the Xperia Z3 smartphone with a slightly rounder edge and reduced metal detailing, plus the signature side power button of course.

The Xperia XA1 Plus slots in between the XA1 and XA1 Ultra in terms of size, but where the previous models offered the older style circular side - mounted power button and no fingerprint sensor, the XA1 Plus adopts the newer oval - shaped side power button with a built - in fingerprint sensor, like the XZ1 and XZ1 Compact that it launches alongside.

There's obviously no sign of a rear - mounted fingerprint reader, as a few fishy prototype pics suggested at one point, with the biometric sensor instead most definitely embedded into that signature side power button. (pocketnow.com)
