Answer to "Why won't my Fit turn on?"Well, couldn't find a new Gear Fit, so, got a refurbished one. That was only 2 weeks ago and already it won't work. Have to take it back tomorrow. Geek Squad won't guarantee the ones THEY work on. lol Glad I didn't waste $100.00 and it last 6 weeks. I have had a lot of trouble with the apps too. Won't work with my Samsung Galaxy Tab 3. I got the Gear Fit just for that reason! When I downloaded the Manager it said "For security reasons, your device is currently set to block installation of applications not obtained from Play Store. To change this. go to Settings > Security > Unknown sources." Where else would I have gotten the app?? lol Anyway, it won't charge. The charger just vibrates. We will see I guess.
