Wow! I wish samsung would do something with their health app! I am tired of people finishing month long challenges in 2 days. I run between 5 and 10K ever morning at 0500 before work and stay on my feet all day... The top of the health app have 150,000 steps a day. That's between 60-80 miles a day! Not even the Olympic athletes can do that. If these people on the leaderboards can do that many steps they would be famous. They are cheating. Please do more to prevent false steps and ban these cheaters! Yosi (no challenge) is the biggest hacker and is the top months in a row.
