having had the phone 8 days now the initial "oh, i think i prefered my gold z5" thoughts have faded away.
why did i have those thoughts? because while there is a big similarity between the z5 & xz1 (and everything since the Z1) there are a couple of slight changes that take a little getting used to. and once you have it feels as natural as the z5 was to use.
it has "crashed" to a reboot once. no idea why. it was playing spotify at the time
the sound is TOO QUIET both through ear phones and through the speakers. I don't think it is any louder than the Z5 was, and that is annoying... it needs to be louder especially for calls/notifications.
the battery life is awesome if it is lightly used. like any large screen phone if the screen is alive the battery power will be eaten up but for things (like music play) it lasts muc better than the z5. The z5 i charged daily, the xz1 could be done every other day with the same fondling.
i am not sure which i prefer, the silver metal back (xz1) or the gold glass back (z5) to look at both have plus points - but to hold it the xz1 is better.
i have not noticed the wifi issues or the sms issues the z5 had with 7.0x & 7.1.1 8.0 on the xz1 seems very good.
photos i have taken seem fine. the slow mo video is great (try it with a bagless vacuum cleaner) but it does need very bright situations. the 3d creator needs a person to sit through a tutorial test scan before any other function can be used - that was annoying.
