In front of me is Xiaomi Redmi Note 10S and let me show you how to use secret codes on
0:11

0:18
And now let me start with the first code, which is asterisk pound, asterisk pound, 6485
0:25

0:51
If you'll tap on more icon, you will be able to enroll advanced view here. And here you've got it
0:56
And that would be all about this code. Another one, I think it's my favorite one, will open the test mode
1:03
So just provide the quite long code. It is asterisk pound, asterisk pound, 64663, pound asterisk, pound asterisk
1:14
And here you can test your device. So if you experience any issues with, for example, display or receiver, whatever, you
1:21
can check it here if it's about your application or device itself
1:25
So let me check the display. Just click to continue and red is perfect
1:31
Tap to switch it to another one. Click one more time. It will also work properly
1:38
And tap on OK to complete the test. And now you can check also receiver
1:44
So just enter the numbers that you hear and tap on OK
1:48
And then if you'll go back, you'll be able to see if it passed or not
1:51
This is how you can test your device here. And then another code that you can provide is asterisk pound, asterisk pound, 225, pound
2:01
asterisk, pound asterisk. And here you've got the calendar info. So if you have any important events, birthdays, celebrations included in any calendars of
2:13
yours, it will be all included here. So it will store data from Google Calendar, from devices, internal storage for iPhone
2:19
Calendar if it's connected. All you need to do is provide this number and then you'll have the calendar details
2:28
And another code that I would like to show you is asterisk pound, asterisk pound, 4636
2:35

2:44
And here you will be able to check email number, phone number, current network, signal strength
2:48
voice service, data service, and so on. A bit lower, you will also be able to run a ping test
2:53
Just click here and below, you've got the results. If you tap on more, you will be able to view SIM address book, fixed dialing numbers, service
3:01
dialing numbers, IMS service status, and enable data connection. So let me go back
3:08
And then under Wi-Fi info, you have Wi-Fi API, Wi-Fi configuration, and Wi-Fi status
3:13
So if you want to check any of them, simply click to open, but also Wi-Fi status allows
3:18
you to perform a ping test. That would be all. And the last code that I would like to show you, it's the shortest one, it is asterisk
