I love that my S8 has a heart rate monitor! I once saw a girl and I wanted to prove to her that my heart was beating really fast! I open samsung health and start the heart rate monitor! We dated for a year!
I had some files in my phone that my parents weren't supposed to see... My father asked to see my phone and I didn't know where to hide those! And sudeenly I thought of Secure folder! Damn it saved me from getting grounded
