I'd like to recommend creating a account so me or other members can assist you, as guest have limitations in replying here and if we need further Information to communicate with you.
All of that seems perfectly normal. Unless you have something specific which seems unusual let us know. If you interact with a phone, you are using it. Dismissing notifications is normal. Device settings can change if an updates or a new app is installed or you may have tweaked the phone. I see no issues. Don't waste your time on this.
