1: Sleep Mode
First thing I noticed was that sleep mode might work well, but there needs to be a setting to lock the screen while sleeping! I woke up and called 2 people, rearranged my home page, and deleted a few icons! Not sure how I was able to do this in my sleep, but more need to lock the screen! I solved this issue by turning off gesture wakeup.
2: Indoor workouts
How do they not have the ability to track indoor workouts such as spinning or general fitness? I was hoping by getting the Neo that devs could write their own fitness apps that fix Samsung's issues. Turns out Samsung isn't opening the SDK to developers for this! My solution has been to only track heart rate using the running app, but my calories don't get tracked.
3: Took it out for a 20 mile bike ride, the screen would constantly show me going 89mi/h... I mean I might have been going 19mph but 89?!? It wasn't just once, it was the entire time. The summary page showed accurate results but not live...
