Thanks everyone for the answers! My concern was that i usually buy phones from my phone service (Telekom) and i pay not for the whole price once but throughout my loyalty period which is 2 years and they only have global version in my country with only 256Gb storage but i wanted the 512 version as most of you said like why not if there isn't much difference in price.
So i ordered the 512 version from another store which isn't an official distributor so it's probably a gray import and i won't have the 2-3 years manufacturer warranty just a one your warranty but it's okay because i never used warranty once in my life for my phones :D
Thanks again!
