Since the last system update on May 14, 2021, My Bluetooth on my phone, Galaxy Note 8, has been coming on automatically EVERYDAY since this upgrade even when I don't use it. It will come on AFTER I turn it offI The giveaway is that my battery will drain. The first for me. I've noticed that Samsung's smart phones become 'Dumb phones' very quickly,. The life expectancy of their phones are short intentionally or because they aren't making quality phones This way they can charge consumers hundreds of dollars for the next new model. Genius!
