over in the "Hands On with the Sony Xperia XZ1 Compact" discussion:
The small phone lives on!
I've had most of the Sony Compacts, starting with the Z3c, Z5c, and Xc and am very excited that I have another phone to look forward to in this line. I'm glad they're using the same chip inside as in it's larger sibling, and cannot wait to upgrade. Glad they're still certifying waterproof ratings, but might import to get the fingerprint sensor (or use global firmware)
