Here I've got Samsung Galaxy A20e and let me show you all the secret codes on the following device
0:10
So at first you have to open the phone dealer and let's start with the quickest, the shortest
0:14
one, and it is asterisk pound 06 pound. And as you can see, this code will show you the email number and also serial number assigned
0:25
to your Samsung Galaxy. So both emails over here and serial number a bit lower
0:30
Click on OK to go back and now we can go to the second code, which will allow us to check
0:35
a firmware version of the device and the code is asterisk pound 1234 pound
0:43
And that's it. Here we've got all the details about your firmware version so we can check it here
0:47
And now let's go back to phone dealer obviously and it's time for the third code
0:54
This is a very useful one because it will allow us to use the test mode. The code is asterisk pound 0 asterisk pound
1:02
And here it is. Now you can test all the features in your device simply by tapping on some particular tool
1:08
So let me check, for example, the display by tapping on green
1:15
And it's working correctly. Then on blue. Good as well. Then receiver
1:24
As you can hear, as I can hear, it's working correctly. Then we can also check the speaker
1:35
And it's obviously good as well. And then you can check all the other tools in your device
1:39
So if you have any issues, simply activate the test mode and check if it's some application
1:43
or your device to blame. Then it's time for another code, which is asterisk pound 0011 pound
1:55
And now we are in service mode so we can check here some details like network connection
2:00
details or service cell info. Then let's go back to another code, which is asterisk pound 0028 and pound at the end
2:16
And now we can check the battery status here so you have here every information about your
2:20
Samsung battery. Now we can go back and it's time for the last code, which will show us the advanced firmware
2:28
version and the code is asterisk pound 2663 pound. And as you can see here, you've got the firmware version so you can come along with all the
2:40
details regarding it. And also you can check your Wi-Fi version here
2:44
Simply click on refresh Wi-Fi, wait a couple of seconds
2:57
And that's it. It has been refreshed. So that is all. And that was actually the last code that you have in your Samsung Galaxy A20e
