Best uk network for android uodates

[Wbutchart]

Hi, I'm new to the android world and now on the excellent s8. I was wondering which uk network has the best track record for android updates? Is there a clear winner or just perspectives? Know there are updates out there but not received them on three network yet.

Thanks.

If you have an unlocked device, and I think Three devices on contract are, then updates come from Samsung so it wouldn't matter which carrier you are on.

Sammobile is a good source for recent updates.

BTU would be the unlocked SM G955F, and you can search by other carriers.

Good point, that makes things a bit strange through
....no uodates, still in April security and I think Samsung have released mays? If free from carrier shouldn't I have it?
