Be forewarned, Sony keeps updating these phones without properly testing if their updates are safe to use. The end result is more and more people like myself needing to fully flash their phones, lose all their app data and starting from square one at least once a month, I have no idea what Sony is doing but they desperately need to stop. Haven't seen mistakes this bad since the psn hacking crisis a few years ago
