This is the Xiaomi Mi Band 4 that I bought again after using Mi Band 2 3 years ago.
The biggest feature of Xiaomi Mi Band 4 is that it is the first device in the series to officially support Korean .
Also , one of the features is that you can use a smart watch at a low price of 31900 won ! hehe

How to use Xiaomi Mi Band 4
Pairing with a smartphone
To use Xiaomi Band 4, you must first pair (connect) with a smartphone app. To connect, you need to install the Mi fit app on your smartphone.
① Install Mi fit application on smartphone
If you look at the manual, you can install the app through the QR code as above.
Or , you can search for related apps by typing Mi fit in the Google Play Store or Apple App Store .
② Membership registration and login, profile setting
After installing the app, you need to log in.
I signed up and logged in using my Google account.
Once you have created your profile, a window will appear asking if you want to allow Bluetooth .
Since Smarfton and Mi Band 4 use Bluetooth, you need to allow this.
③ Miband 4 connection
Click’Band’ in Select a device to connect to.
When prompted to connect to the phone, touch the V
Pairing proceeds.
④ Smartphone app settings
It allows access to health data for linkage between Mefit and Apple’s health app.
I have all functions turned on.
In addition to this, it finds and activates necessary functions.
Since Mi Band 4 does not have an AOD function, I turned on the’Raise wrist to check information’function.
This function turns on the display automatically when movement of the Mi-Band screen toward the face occurs.
In addition to this, night mode and weather settings were added.
⑤ Confirmation of Miband 4 pairing

If you scroll up and down the screen of Mi Band, you can check the functions supported by Mi Band 4 by item.
⑥ Change the wallpaper of Xiaomi Mi Band 4
You can also change the wallpaper of Mi Band 4 by pressing the band screen setting.
There are several wallpapers supported, and if you choose a template you like and apply it, it will be applied to Mi Band 4.
You can see that the wallpaper of Mi Band 4 has changed with the iPhone X-like wallpaper.
Personally, I use Mi Band 4 for clock check, alarm and step count.
It seems that there is no problem at all to use it for that purpose.
Next time, I will post about the reviews I felt after using Mi Band 4.
Thank you for watching the long text.
