What thread am I in?
Indeed.
I finally caved and got a smart phone this year, but I don’t trust it to do anything beyond simple web browsing. I won’t even log into the forum with it.
…Why do you have it then? It’s just a small tablet that makes phone calls, and a tablet is just a laptop with no built-in physical keyboard. It’s a computer. Why do you have a computer if you’re too scared to use it?
Your wifi will not reenable itself (from being disabled) by itself, but it will connect if it is enabled and detects a wifi SSID you’ve connected to before (if you told it to). If you got a notification about connecting to wifi, it was probably because the business’ guest access point has a confirmation page (ie. “I’m not a robot”) you need to access before it will let you use the wifi.
Also, if your friend had an app that appeared to boot on its own, I’d bet money he has location sharing turned on, and some app (like Google Now) popped up a relevant notification for whatever business you were in at the time. You can turn off location sharing for specific apps, or altogether, if you don’t want your phone to do that.
