The whole experience with this Gear Manager is very frustrating. I think Samsung has a huge boondoggle on their hands. The hardware seems to be very good, but software plain sucks. Gear Manager and its relationship with watch, phone and Samsung Apps is inconsistent, very buggy and very confusing. Took me a month to figure out that, for example, in order to uninstall some apps from watch (especially those that fail to install on the first try) you have to go into Android stock app manager on your phone and uninstall from there. My Gear Manager sometimes shows available updates for apps, sometimes doesn't. If I close it off while inside one of the categories ("Clock", "Utilities", "Lifestyle", etc it does not reopen. Just hangs there. I have to go back to list of categories for it to start working again. Two months after release number of apps is still ridiculously small - well under a hundred.
Updates to apps fail to install - "connection with device is lost". But Gear Manager shows Gear 2 connected and communicating. Notifications stop and start working randomly.
At this point I just hope that either Samsung updates Gear 2 to Google Wear OS or I can get at least couple hundred bucks for it on eBay and buy one of Google Wear watches coming later this summer.
