If anyone is having issues with Bluetooth on s21 ultra? My active 2 watch keep on disconnecting within range of no more than 10m. Previously connected to s10 without any problems whatsoever. Also my wife's active 2 works without problems connected to s21. I was hoping that problem will be resolved with last update but it is still here.
A possibility may be the power saving mode that may affect connectivity if activated in watch | phone. For the software part, go to Galaxy store, install Galaxy labs, open, look for Galaxy app booster, install and run. It may take a while, but it's gonna fix many software issues.
