Keep getting a sofware-update notification after updating

[Loes]

I've updated my phone this morning. When it was done the notifaction of the software-update showed up again. I updated my phone again, hoping it would go away, but no, the notifaction came back. I already tried turning my phone off and on but it did no good. Does anybody know what to do? I don't think that just updating my phone is the answer, because I'm pretty sure I'll get the notification again.

Hi @Loes

If you want to be shure you have the laatste update then use Xperia Companion and do a software repair after you have made a backup.

If you want to check which is the most recent version then look up your device in xperiablog.net where you can find which software version is the latest release.
