Question Mi Band 4 - Heart Rate issue.

[JCFB]

Hi all,

Does anyone one had problems using Heart Rate function on mi band 4?

Basically the sensor doesn't work, no green LEDs flashing...

I made a lot of test and I think the problem is on the sensor.

I bought 2 bands last week and one is working fine and another one had this issue.

Any idea?

Thanks,

Best Regards.
