Fair enough, let's not have this discussion start spiraling into something that isn't helpful to anyone.
So boot into Safe Mode and tell us if the problem still happens. You said it happens every few minutes using the Samsung browser. This should make it easy to figure out if the problem is due to something you installed vs some issue with the system. If it doesn't freeze in Safe Mode, then something you installed is causing the problem. The challenge then is to pinpoint the app -- that might mean uninstalling apps one by one until the freezing goes away.
