Welcome to Vodafone Community
Link? I haven't seen anyone mention anything on twitter, Samsung forums or this forum, haven't recieved the update either, where did you get that info from?
for samsung users you can check here as i do daily, every other uk network got it mid jan but we are still waiting, i am on the beta version and quite like most of it but because its beta some things i use figerpring access for dont work which is no biggy just a bug bare, im hoping dark mode works on the final release as i had to turn high contrast font on to read most things
it was written for vodafone as my phone is network locked and its a pain to unlock so i just waited about a month into the beta release on the S9+ and a voda version showed up, i have always used the upgrad softwares from that site as its usually quicker than ota and hav had 2 devices in for warranty issues in the past that have been updated this way with no issue, i dont root the phone so it doesnt affect the counter thus not invalidating the warranty
if i wasnt so impatient i wouldnt do a beta install again, it has halved the battery run time near enough and not all features are working properly as i belive it was aimed at the not for primary testing and the s9 as an after thought, also as said beta test is now closed, im not sure ill get the stable release any sooner as vodafone are really in control of that with their extra testing
