I have sent back my 3rd active 2 for hopefully replacmement and new device away from the Active. All watches have had overheating problems with red triangle warning showing up and then having to wait for it to cool down before beng able to use it again. Yesterday the screen blacked out and was unresponsive even though I could hear the notifications and ringing. Has anyone else had these issues and been so unlucky with their active 2 watches? I am a Samsung fan!
