Hi everyone in front of me I've got Vivo v21 and let me share with you some useful secret codes which you can use on this device
0:12
So first of all let's open the dialer and tap on the keyboard because this is the place where we'll enter all of those codes
0:17
and let me begin with the shortest code and probably the most known which is asterisk pound 06 pound
0:25
And as you can see by this code we are provided with both in my numbers and also a serial number at
0:29
touched to this device. Let me tap on OK and let me show you another code which is actually
0:34
very similar to the previous one. It is asterisk pound 07 pound. And as you can see thanks
0:41
to this code we can open the SAR level so here we can check the head and the body of our device
0:47
Let me tap on okay and let me show you another code which is again very similar to the to the first
0:53
and the second one. It is asterisk pound zero nine pound and thanks to those general information
0:59
which are opened by this code, you can check again the email number, the barcode
1:05
network access name, you can check the ROM size, and scan those QR codes in order to check
1:11
your device more. So that was all for this code and let me show you another one which will open the factory test it is asterisk pound double five eight pound and as you can see here we got the factory test
1:26
so here you've got the debugging port you've got the QC test and the settings so after for example
1:31
tapping on the settings you're able to to check the privacy terms and your rights and so on and so
1:39
you can learn a little bit you can also tap on it the QC test
1:43
and here you can of course scan this QR code let's pretend that I have scanned it so let me tap on it
1:50
and here you've got two different modes two different tests so you've got the FQC test and OQC test
1:58
so after tapping on this one for example you can check the brightness test the phone info camera
2:03
Bluetooth test fingerprint tests and so on so here you've got some components of your device
2:10
which you are able to check and after getting back again You can also enter another test and here you've got something like the Simlock State, Factory, Reset or the E-May
2:21
So I highly recommend to have fun with this section because not only you can have fun, but also you can check the components of your device
2:29
So that was all for this code and as I said I highly recommend to stay there and have fun And let me show you another code which will open the version test It is asterisk pound asterisk pound double to five pound asterisk pound asterisk
2:44
And as I said here we've got the version test. So here again we've got some technical info like the network access name
2:50
up version compile time, the barcode, the secure boot or the email numbers and so on and so on
2:58
Let's get back and let me show you another code which will open the diagnostic
3:02
It is asterisk pound asterisk pound four to six pound asterisk pound asterisk and as I said we are in the
3:09
Diagnostics so here we can check the server host port time connected or sign a level will also appear here if you will have the connection
3:18
once more you can tap on events and as you can see you've got some further details after tapping on the 3
3:24
I can and tapping on advanced view and getting back you will be able to check some more information just like the heartbeat or
3:32
or HB algorithm. Let me get back and let me show you the last code
3:37
which will open the testing menu. It is asterisk pound asterisk pound 46
3:44
336 pound asterisk. And as you can see here we've got the phone information
3:50
usage statistics and Wi info So let me first of all check the phone information and as you can see here here you can check the email number for example car network data service or data network type
4:03
What's more, you can run Pink Test here and here you've got the results
4:06
After tapping on the 3 to second, you can also enable data connection or view service dialing numbers
4:12
Let's get back and let's check for example usage statistics. And as you can see here, we've got the list of all apps and processes which are right now on this device
4:20
And at this moment they are sorted by the usage time. So you can, for example, check that I've been using the settings for five minutes
4:29
What's more, you can change the sorting type, of course, to the last time use or app name
4:33
And of course, after picking the app name, all of the apps will be listed alphabetically
4:38
Let me get back and let's check the Wi-Fi info. So here we can check the API configuration or the status
4:45
Let's pick the status. Let's refresh the stats. And here we've got the info like the network
4:50
state SSID or network ID. Of course we can run pink test here also
4:54
So actually this is it, this is how to use secret codes in your Vivo v21
