Hi everyone, in front of me I've got Blackview A90 and let me share with you how to use secret
0:12
codes on this device. So first of all let's open the dialer because this is the place where we can enter all of
0:18
those codes and let me begin with the shortest one and probably the most known which will
0:23
open the email info. The code is asterisk pound 06 pound. And as you can see by this code you are provided with both email numbers and also a serial
0:32
number attached to this device. So let me tap on OK and let me show you another code which will open the calendar info
0:40
And the code for it is asterisk pound asterisk pound double to five pound asterisk pound asterisk
0:47
And as I said we are in the calendar info so here we've got all the events in one place
0:52
We can check some family events, some holidays in your country should also appear right here
0:56
or events attached to your mail. So this is the best code to use if you want to check the events because here they are
1:03
grouped into particular sections. Let's get back and let me show you another code which will open the diagnostic mode and
1:11
it is let's say a technical code. So the code for it is asterisk pound asterisk pound four to six pound asterisk pound asterisk
1:20
And as you can see we are in the diagnostics so here we can check the server, host port
1:24
time connected or SINA level. We can tap on events and here we've got some further details
1:29
After tapping on the three dot icon we can show advanced view, just tap on it and tap
1:33
on the status again. And as you can see here we've got much more info
1:39
So for example we can check the heartbeat, last ping or HB algorithm
1:44
Let's get back and let me show you the last code which will open the testing menu
1:48
And the code for it is asterisk pound asterisk pound four six three six pound asterisk pound asterisk
1:56
And as I said we are in the testing mode so here we can check the phone and Wi-Fi info
2:01
and also usage statistics. So let me begin with the first option
2:05
As you can see here we've got some info just like the email and the phone number, roaming
2:10
or data network type. Of course I know that I do not have any info right here
2:15
It is because I do not have my SIM card inserted. If you've got one, no worries, you will be able to check those details
2:23
You can run ping test here if you want to. Here we've got some further details like the carrier provisioning info
2:32
If you want to you can tap on the three dots icon and here you can enable data connection
2:36
or view service dialing numbers. Let's get back, let's enter usage statistics and as you can see we've been transferred
2:42
to the list of all apps and actually all processes which are currently on this device
2:48
Currently they are sorted by usage time but of course we can change it to the last time
2:51
used or app name. For example after tapping on app name everything will be listed alphabetically and of course
2:59
you will still be able to check for how long you've been using a particular app, so for
3:03
example the camera, for above three minutes. Let's get back and the last option, the Wi-Fi information
3:10
Here we've got the API configuration or the status. So let me for example enter the status
3:16
Let's refresh the stats and as you can see we can check the network state, SSID or network
3:21
ID. We can of course run Pintest here. So actually this is it, this is how to use secret codes in your Blackview A90
