Weird one this is. Just downloaded security update for April 1st and it's only 31st march, plus from my past experience I've never ever had any updates this prompt. So just wanted to say well done Samsung I'm quite astounded. 👍👍👍 Cheers
Update - everything downloaded ok. Only 160mb ish file size as you can see by the screenshot, just says security and stability is improved. Proves I wasn't in the twiglet zone and imagining it 😂
