Ive had the Gear 2 for 6 days. I bought it last thursday, put it on and paired it in the parking lot and then went to the gym. While riding the recumbent bike I noticed the heart rate monitor was accurate and matched up with the bike's up until around 125 bpm and then it would either give me the "cannot measure" error or would give back a really inaccurate reading... like 71 bpm when it should have been around 148-150. This has been the case every time i go to the gym, no matter how i wear the Gear 2, on the top side of my wrist or the bottom side. I actually live chatted with a Samsung Customer service rep and he told me to do a factory reset to see if that would help. I haven't gone to the gym to see if this helped.
Is this a known issue? I also shaved the hair off my wrist and am now wearing it a bit further up on my arm to test it again today when i go to the gym.
Also another question i had is when you turn the volume all the way up (level 6) when using the gear 2 as a speaker phone is it normal for the speaker to buzz slightly when a person is talking to you?
