Word from the grapevine is that the
Sony Xperia Z4 will feature not only a metal chassis,
which we saw in the leaked frame comparison with the
Z3 not long ago, but in fact an all-metal body, probably akin to the
Huawei P8 that was just announced yesterday. Now, whether that means Sony will do away with the glass rear it pioneered for the Z-line, or do something similar to the
Galaxy S6, remains to be seen, but it's the other nugget of info in this latest leak that caught our attention.
The Xperia Z4 is now claimed to introduce a fingerprint scanner, which won't be a complete surprise for a 2015 flagship, of course. The placement of the sensor is said to be unorthodox, though - embedded in the power key. Such a placement would be perfect, if Sony can pull it off, as you want have to stretch your thumb or another digit all the way underneath the display just to unlock your handset or authorize payment, risking to drop it if your mind is not into it.
