So i had my Xperia xz1 from Dubai which is already on the latest firmware update of June (47.1.a.12.205). And right now i reside in India ?? where am using Jio Volte network but my u Xperia ain't showing any options to switch on volte and then i came across some feed which suggests to change the firmware on basis of country region. So my question is which country firmware should i download depending on the fact that i don't loose any other features and which country is the first to receive the latest firmware updates.? And please suggest a link which can guide me to change my firmware.
Thanks.
Thanks.
