Try flashing it with original firmware

what kind of XZ1 you got?
if it's Japanese XZ1 AU(SOV36) in this case, just like mine, you have to stick with original ROM from AU Japan..
if u flash it with global firmware, you'll encounter that randoom restart / reboot problem

no, I didn't own one yet. as i am among those who use latest custom rom on their daily driver, i found X Performance to be frustrating. No official custom rom support from anyone, kernel 4.4 and 4.9 wifi problems, no further updates from sony open devices project and for sodp 4.14....yeah. this phone is dead as a dodo

i thought xz1 might worth an upgrade. tremendous performance upgrade than 820, ufs 2.1, lpddr4x memory.....there are two custom roms that i see has official support for it. carbonrom and pixelexperience. i saw xz1s scattering around my online local marketplace that some people say they got random reboots, some say not.

thanks for advice. I'll be looking forward to buy the version as you suggested. i hope i can stick with it at least a year....
