My service is via Metro PCS > by T-Mobile. This is a Samsung Galaxy J2 model SM-J260T1. I don't know if it is a 2018, a core or a pure. I also can't find the slider switch to let unknowen app's to be installed. I looked in settings > security, where I have found it before in other phones that I have had. Also can this phone be rooted? There is a few ham radio app's that I would like to use that need the phone to be rooted.
