I just updated my Samsung S5 to Lollipop 5.0 two days ago. Now the heart rate monitor light comes on anytime the screen is on and something is near it or it is sitting face up on the desk. The WiFi also is constantly scanning and changing networks. The phone also went into cool down mode today and the battery is draining from a complete charge in 6 hours with little use. I reached out to Samsung and they were no help. I have read posts online from many users having these same issues. Any other users having the same issues? Any suggestions on a fix? I have restarted several times and cleared all applications cache with no luck. I hate to have to do a factory reset but that is looking like my next step or possibly downgrading (more like an upgrade) back to KitKat 4.4.

Thanks,

Mark
