What ho one and all,

I am very much a 'smartphone' rookie, having had one for only a few months. It is a Samsung J5 and I really only use it for phone calls and some (I want to remember that) photos. Occasionally use Google for something trivial but I don't use my phone to access the internet.

But I did, and now when I power-up, there is s Google message asking 'Did you sign in? New device accessed your account.' It was probably me signing in, but I have no idea how to delete this message.

Grateful for a 'this is how yo do it' assistance.

Thanks and toodle pip
