I’ve had almost every phone out there. Currently running a Sony xperia z ultra which is the big version of the z. It is the same phone more or less just a much bigger screen. While I love big phones (phablet) I have not had such a glitchy phone software wise for a long while. If you constantly use the flap for the charging it will stop it being waterproof, Sony basically admit this hence the magnetic charging which isn’t a touch on say the macbook setup as it’s way too fiddly to get the connection right. Although I like the phone, sounding a bit negative about it I know, I won’t go back to Apple as I don’t like dumb downed phones. Both are good but both are far from perfect.
