I've had my Vivosmart 4 for over a month now and the HR has always been accurate up until last night. I had come down my home stairs and went to check my steps and as i flicked through my HR was at 155, queue my panic as i would normally only be around 70-90. Its shown all through the night my HR over 65 which is high for me and again this morning, simply standing up elevates the HR reading on the band to over 130. Has anyone had this issue with this band before?
I have checked my pulse manually and it is no where near this high readings the band are recording. Its knocking my stats off completely. Can anyone help?
