App incorrectly recording steps

When I first got this device and app it worked perfectly. Now, my steps barely register. Even adjusting the height to 3 foot 11 I only get about 700 steps maximum Per day where I used to get 7500 to 10,000 using my correct height of 6 foot. The accelerometer must be miss calculated or something hopefully you can fix that. Additionally app support is only in Chinese which is no help for us English speaking people, I couldnt even figure out where to click. The us measurement additions are a plus though. Only reason for this review is to get app and device measurements corrected.

Well u fixed the mile/kilometers issue but didnt address the real problem... Inaccurate step counting... I still get about 700 steps when it is set to 311" and I am 60" tall... Should be at least 7000 not 700.
Come on now.

I did translate Chinese page and there is nowhere for app support at all. So get it together.
