I put down my Samsung Galaxy S7 phone after making a phone call, and then noticed that the settings appeared on screen, and things like "reset password" were being clicked and text was being entered into password fields for my Samsung and Gmail account.
After unsuccessfully trying for a few seconds to get this to stop, I completely switched off the phone. I have since checked my accounts from another device, and nothing (visible to me) seems to have happened there.
I had been warned about an OS update yesterday, but stupidly clicked to install it later. Now I'm wondering whether there's anything in particular I should do when (or before) I switch on my phone again. Does all this sound like the symptoms of the Android vulnerability that has been in the news this month? And if I get the update installed, will this also check whether the vulnerability has been exploited?
