I notice that the Samsung Gear app is now officially installable on other Android handsets. Does that mean the Fit 2 & Gear S2 now work properly with other Android phones (not just Samsung models). I've seen new Gear Fit 2 on sale for less that €150 and the S2 for €200, but if it locked you to only one android device maker I wouldn't bother buying. Anyone experience with either device working with non Samsung devices ?? If so - did everything work or were there lingering issues ? Also how I'd the battery. I had the iriginal Gear Fit and would get 2-2.5 days battery tops. Has this improved ?
