Mi Band 4 could not measure heart rate

[EBKopec]

I have bought recently a mi band 4 and when I was setting it up I could not measure heart rate and I do not know why.
Does anyone faced this problem and have fixed it?
I already have reinstalled MI FIT from my Redmi Note 6 PRO, reset factory the MB4 and paired with Amazfit app and I got the same result.

I am looking for the ROM to reinstall the firmware of MB4 as well but unfortunately, I could not find any tutorial or link to reinstall the firmware on it. If someone has the ROM and the software to reinstall the firmware I will be glad.

I have the same problem, I opened a support ticket for customer support and I am awaiting a response. I noticed that the sensor does not switch on, the LED remains off.

You might have luck with this manual installation of custom ROM. However I do not know how to return to 100% stock, should you want to apply for your warranty (no idea if the service center would check FW version). https://geekdoing.com/threads/international-firmware-for-mi-band-4.970/

I have a strange heart rate monitoring issue. I can manually check the rate at any time and it works without problem. I have the band set to check every 10 minutes and during sleep too. Once in every 5,6 days, heart rate is not recorded for duration of about 1 hour.
I did factory reset but didn't seem to help. I thought the sensor wasn't clean, so I was periodically but doesn't seem to fix. It's not too loose on my wrist, I see the mark of sensor on my wrist when I take off to ensure it's not loosely fitted. Don't know what's causing this strange behavior.

Is your green LED blinking during HR measurement? If not, ask for a warranty repair/replacement.

Have you tried fastening/loosening the band on your hand or measuring on the underside of the wrist?

Same problem here, I can do it manually by putting the sensor at 1cm from my wrist (as stated I don't remember where)
but it dosen't works automatically to monitor while sleeping for example.

Hi, some days ago just received a brand new Mi band 5 and today i realised that presents the same behavior that you described so i wonder to ask if you found some solution to this problem.

Actually this is the only information about this problem with the mi band HR measurement.

Actually this problem disappeared one day without trying anything, strange.
Hope yours get fixed too.
