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 a
fingerprint sensor below the screen, a rounded «Batwing» divot on the back, and a
circular camera module with — and this is
new — two
sensors instead of one.
