System software update hit today, so naturally I click update as it states security vulnerability. I go about my day, wondering why no comms. No WhatsApp, no Google Duo, no Viber which is how I do my communications for past decade +. All say I'm offline even though I'm online. No matter wifi, cell or even both, wiping app cache after force stops and even system cache did nothing. Phone isn't 3 weeks old so pretty frustrated any help possible I'd appreciate i will have to return the phone if it's just a paper weight.
