As this is my first thread I would like to say Hi to everyone.

I purchased a pre-owned Samsung Galaxy S20 in December but have not received any automatic security or android updates on the phone. I believe this is due to the phone being of South American origin and me living in the UK with a UK sim installed. Am I right in thinking that if I want to update then I will have to learn to do it manually. I have not delved into the tech or software side of smartphones before and would really appreciate some advice on the subject. I can find my way around computers so I hope I can do the same with a phone.
Many thanks.
