Don't know what it is about this phone in particular but the apps have never automatically updated. It's the first Samsung phone where I've had this problem. No apps whether they come from the play store or from the galaxy store will auto update even though that option is clearly selected. This phone has had several bugs over the years. I think I've just gotten used to them. It's time for me to upgrade and I'm really taking a hard look at non Samsung phones this time around.
