Xz2 software update keeps failing

[S20]

Every time my new xz2 attempts to download its software update it fails and then a notice pops asking to close the app. Can't seem to switch off the update to ignore it and phone won't complete the update so it's stuck in limbo. Any ideas?

I would try to wipe the cache of the Updater first:

Phone settings --> Apps --> Press on the 3 dots and select System Processes --> Update Service --> Storage --> Erase Cache and Data.

Then reboot and try again.

If this doesn't help try using Xperia PC Companion to update the phone.

I don't have that sequence of actions. I get this screen then it shows and "app has crashed. Restarts app?" window. Restarting app just causes the same result over and over.

Sorry its a "software update keeps stopping. Restart app?" window.

You don't need to open the Software Update App. Just open the general phone settings and do as described before.
