Hi, I bought my Galaxy S20 over a year ago and have been with o2 the entire time. Since I bought the phone, it hasn't received a single update. No Android 12, no security updates, nothing. The only odd thing I can find about the phone is that the servicer provider software version is registered as "TIM" which corresponds to an Italian version. I called Samsung, they said this doesn't matter and the only thing holding back my updates is o2. I called o2 and they said the S20 hasn't received any updates in a year (this is factually incorrect). Anyone have any idea what is going on? Thanks.
My Luxembourg based S20+ has updated fine on both Vodafone and O2
O2 use Vanilla firmware so should not be a problem
You can search on this site to find the latest for your phone
It has nothing to do with o2, it is Samsung who control the update process, and it looks like your phone has been missed by SAMSUNGS update service.
Updating manually does not affect the warranty, at all.
If you have had the phone over 14 days, then if you want to return it then o2 will just send it off to Samsung, unless you pay off the device plan in full...
