I have not had my Gear 2 reset itself (yet), but every time I re-connect my Gear 1 after using the Gear 2, the Gear Manager for the Gear 1 DOES RESET ITSELF back to the default settings! This really pisses me off because it is a major headache to get all of my notifications setup again in the GM without it freezing/crashing due to the tons of apps/games I have installed on my Note 3.
Just so you all know, going back and forth from the Gear 1 to Gear 2 is NOT at all seamless and can be a true pain in the *** because the GM will constantly have to restore and/or re-install it's software EVERY TIME! Samsung really didn't think this through very much at all, but their tech support "says" that they're working on it.
