Yesterday my Galaxy Active 2 watch's touch screen was unresponsive. I reset the device via the wearables app on my phone however it will not let me move past the a screen with the message "Try again. Touch screen with your palm to turn it off". I have tried multiple ways to move past this screen including turning off the watch and phone to no avail.
I sent it in for water seal replacement, but Samsung insisted the motherboard and touch screen needed to be replaced as well (despite working correctly when dry).
They wanted nearly $250 for the repair, so I just had them return it unrepaired, and decided to put the $250 toward a Garmin Fenix 5x Plus, which was just $70 more, brand new.
The Watch Active 2 still works fine, but I know I can't submerge it any more, so I'm just wearing the Fenix full-time now.
