Hi everyone, in front of me is Vivo V20 and let me share with you how to use secret codes
0:12
on this device. So firstly let's enter the dialer because this is the place where we will enter all
0:17
of those codes and let's begin with the shortest one and probably the most known which is asterisk
0:23
bound 06 bound. And as you can see by this code we are provided with both humane numbers and also a serial
0:29
number attached to this device. Let's tap on OK and let me show you another code which is actually quite similar to the
0:37
previous one. It is asterisk bound 09 bound. And as you can see here we can check also the email but we've got some information
0:47
some more info just like barcode or software built version. Let me get back and that's not the code which I would like to show you right now
0:58
And let's enter the code which will open the testing menu. It is asterisk bound asterisk bound 4636 bound asterisk bound asterisk
1:08
And as I said we are in a testing mode so here we can check the phone info, usage statistics
1:12
and Wi-Fi info. Let's begin with phone information and here we can check again the email number but also
1:20
the phone number, current network data service or voice service. Unfortunately you will have to enter your SIM card
1:27
I do not have mine inside this device so that's why I cannot actually check anything
1:33
What's more we can run ping test, just tap on it and here you've got the results
1:37
After tapping on the three dots icon you can also select ratio band or enable data connection
1:43
Let's get back and let's check for example usage statistics. And as you can see here we've got the full list of all apps and processes which are currently
1:53
on this device. And here for example we can check that I've been using the settings for above one hour
2:01
We can change the sorting type to the last time use or app name so obviously after picking
2:06
the app name all of them will be listed alphabetically. Let's get back and check the Wi-Fi information
2:14
Here we can check the API configuration or the status. I will pick the status
2:19
We can refresh the stats and as you can see we can check the network state, SSID or network
2:24
ID. Of course we can run ping test here also. Let me get back and let me show you another code which will open the factory test
2:37
It is asterisk pound double five eight pound. And as I said we are in the factory test
2:43
If you will open it for the very first time then you will receive an information and a
2:48
warning that the factory test is a very advanced option and mode
2:54
So be careful whilst doing something here. Here we've got engineering test, quality verification test, query, email reset
3:04
You can also reset your device to factory settings. We can check the software information, privacy or QC test
3:12
I think the most interesting option is the engineering test because here you can enter
3:18
and actually check some of the components of your device. So as you can see for example you can check the gravity sensor test, screen brightness
3:26
test, wake up test and so on and so on. We've got three modes, three options
3:34
So I highly recommend to stay here but remember be careful. So that's all for this code and let me show you another one which will open the version test
3:47
It is asterisk pound asterisk pound double two five pound asterisk pound asterisk
3:53
And as I said we are in the version test so here we've got some technical info again just
3:58
like a product name, software build version, compile time, barcode again, ABI version number
4:04
serial number, version, secure boot and so on and so on. So let's get back and let me show you the last code which will open the diagnostics
4:14
It is asterisk pound asterisk pound four two six pound asterisk pound asterisk
4:20
And as I said we are in a diagnostics. Here we can check the server host port because I'm not connected to the Wi-Fi or the internet
4:28
then we cannot check more info. We can tap on events also and here we've got some further details so that we failed the connection
4:37
We can also show advanced view, just tap on the three that I can get back to the status
4:42
and if you will be connected to the Wi-Fi for example then you will be able to check
4:49
for example last ping or HB algorithm. So actually this is it
4:54
This is how to use secret codes in your Vivo V20. Thank you so much for watching
