My newer phone A14 Samsung had a pop up trying to connect my phone via Bluetooth to my old phone which was turned off. Somehow it was turned on and its bluetooth enabled as well as my new phone somehow had it's bluetooth turned and tried to pair. My old phone had my new phone paired but I haven't used my old phone in over a year. Hacking maybe?
If after this it continues to try to connect on its own and turning on on its own, it may be a third-party application that is the culprit. You can see tis with Safe mode: https://www.samsung.com/us/support/answer/ANS00062983/ If the behavior is not present under Safe mode, then remove third-party applications and restart each time until you find out which app(s) were causing this to occur.
If the troubleshooting is not helpful, the phone will need to be evaluated by a certified technician. For service in the U.S., you can take the phone to a local U.S. walk-in service location https://www.ubreakifix.com/samsung or to ship the phone in for service, please reach out to us via one of the following options:
