I asked my husband to call someone. He opened his phone while it was in his hands on bottom eye level. I saw a WhatsApp open saying I love you, followed by a love you too. Instantly I asked him who it was. He took the phone and called that person and said it was no one and said I was imagining things. He handed me the phone and asked me to check the phone. It’s a Samsung 8 Galazy. And I am an iPhone user. I opened WhatsApp and searched for “I love you”and couldn’t find I love you or I love you too in any recent msgs. Went ahead and opened Instagram and Facebook and couldn’t find anything there. Somehow I stumbled Upon open apps and saw a WhatsApp icon with a lock on it. The second I clicked on that this popped up (pics attached ) and I went ahead and Google’s “secured by Knox” and I found out there is something such as a secured folder. I went ahead and got onto Samsung website and went on live chat and they told me that via a secured folder you can have another WhatsApp account. I stormed to my husband asking him for the password of this account (now mind you he’s an IT guy) and somehow he didn’t know his passwords. So I clicked on forgot pin and his email address came. I made him go to his Samsung account online and somehow he couldn’t get any passwords in. And then he linked some stuff up. He got a pin and he added that in. And some mountains in pics came up which he clicked and then some bicycles ( he was asked to select a sequence or something) and then suddenly his phone got reset. He kept saying I did it because I kept putting in correct passwords into the Knox thing. I don’t know if he did it or if I did it. (My husband is a computer engineer) I’m personally devastated and don’t know what happening. And he said he didn’t know why that additional WhatsApp app with a lock was open in his open app tabs. But arnt apps we use and don’t close are present in open tabs. Pls help
