my A13's Bluetooth and WiFi turn off then on again at random intervals while my location is turned on. I tried unpairing and repairing all my bluetooth devices which did not solve the issue. I also cleared the bluetooth data and cache and turned off auto scan. Turning off location is the only thing that works.
Edit: For some it seems long pressing nearby share and turning it off completely also works, which is preferred to turning off location completely. Hope this works for you guys as well until Samsung decides our issue is worth fixing.
