  1. My band has custom rom , I think that’s why it’s not connecting to mine . Is it the case?

  2. It is finding my mi band 3 but didn’t unlock laptop automatically I have to enter pin only.

  3. Dude I can’t see my band’s name on my laptop with this mi blaze. The mi band 3 is not showing up on my laptop.

  4. Ummm

    Can’t you just use windows Bluetooth unlock feature after turning on discoverable in the MI for app

  5. What if the device gets lost? The default login will still be set to Mi Unlock, how can I reset it to Windows?

  6. I just bought the Mi notebook 14 and wanted to use this feature.
    I am facing a few problems….first of all the Mi fit app doesn’t show unlock notebook toggle in Lab tab.
    Even tried the latest apk from net to see if it offers the unlock feature…it doesn’t.

    Also my pc won’t connect to the band as long as its connected to my phone. If i switch off my bluetooth on my phone….the pc connects..and everything works fine.

    I just want to do it the way its meant to be…not by switching off my phone’s bluetooth when i am around my laptop.

    1. I hope you closed and reopened the Microsoft store after changing the region. If it still doesn’t work, try restarting the PC one. Maybe that will apply the region change. It worked for me in the first go, without restarting.

  7. I Have followed you. but it’s not showing me my band (BT is on)
    It’s just searching (I’m stick at the searching screen)

  8. After turning on my PC I had to first unpaid my band from mobile and then it’s unlocking the computer. So I this is a complete chaos. Even on PC I had to select the sign in option. Is there any alternative.

    1. I connected my mi band 4 to pc as well as my phone. I face some delay in unlocking the PC but didn’t face such issue.

  9. After pairing to my PC my band isn’t connecting to my phone when PC is on. Can’t it be connected to both at the same time. But after I shutdown my PC then band gets connected to my phone.

  10. There is no option for lab though I am in india region
    And also my app is updated to latest version as well as firmware
    I am using mi band 3 please can you help me why it is so

      1. Devendra even i am facing the same issue, i also have updated the mi fit app and firmware too. still there is no such option in Lab section

      2. Same problem with my Mi Band 4. Please help! This feature really sounds cool and I want to try it.

    1. Hey bro! I think where you are going wrong is opening the wrong settings page. After heading to the profile page, do ‘NOT’ click on the settings option then and there. Click on your ‘Mi Smart Band 3/4’ that sits right atop the screen. Here you can scroll down to find the ‘Labs’ option waiting for you.
