Hi guys, my family member recently bought a Z Ultra from a phone shop. RM1999 for 3g version with freebies like sp and casing. During the purchase i was not around as I am in my uni. So i could not assist in checking. My family did not ask whether it is dynamics, thorus or midland set too.

The seller claims that it is original and can claim from any Sony center. Just went through Sony's Malaysia website. There's only lte version officially from Sony. This made me feel suspicious. But my family member's set is 3g. I doubt whether it is original.

is there anyway to check? And also for the warranty, need to register online?
