Flashback: the Samsung Galaxy S II was a best seller, its variants ushered in the 4G era

This week Samsung unveiled three Galaxy S20 phones – well, six models actually, as each phone has a 4G and a 5G version. If you think that’s a lot of models, then you don’t remember what happened when the Galaxy S II was unveiled. The Samsung I9100 Galaxy S II was announced nine years ago in February 2011 and released in April that year.
