Security patch. Update problem

[EagleEye2]

I have an XZ1 stuck on April security patch.

May is passed and now the same will be for June, but still can't see a security update on this phone.

I tried with a reset using Xperia Companion, tring to find update via OTA but nothing changed, April is always the latest version available.

What do I do? I don't really want to root a new phone, I bought it also because I was sure to receive constant updates

@EagleEye

Updates are released gradually and timing will differ between markets and their availability depends on a specific characteristic of your device called "customization version". You can check this version by dialing the code *#*#7378423#*#* the tap on "Software info". Use this version on a site like Xpericheck.com to see the latest version available to your phone.
