I am using a Samsung Galaxy s7 Edge with up-to-date OS. This has happened four or five times over the past two months and the pattern is the same: I am browsing regular websites - the most recent was a food recipe - the browser will freeze, then the phone will freeze, then the phone will restart. Sometimes everything will be fine after the restart but a couple of times, today being the second, the phone will get stuck in a loop where every minute or so the phone will freeze and restart again. The only times the phone has gotten into this pattern is when I've been browsing but it doesn't happen every time I use the Firefox browser.
