In front of me is Samsung Galaxy Note 20 Ultra and let me show you secret codes that you
0:10
can use on this device. So first of all you have to open your phone dialer and here we will be entering all the codes
0:17
Let me start with the first one which is asterisk pound, 2663 pound
0:23
And as you can see this is the advanced firmware version, you can smoothly check all the dates
0:27
regarding your firmware. Here it is, you can also refresh WiFi if you want to and just read all the info that you
0:35
need to come along with, then go back and this is it
0:40
Another code that you can use here is asterisk pound, 0808 and pound at the end
0:46
And here you can manage USB settings so just pick the option that you want to apply and
0:52
just by tapping you can change it. Then go back and it has been applied
0:57
Another code that you can use, truly useful, is asterisk pound, 2683662 and pound at the end
1:07
And here we've got service mode, if you will tap on the more icon you will be able to check
1:11
key input, you can select the row, you can open help with some further details, you can
1:19
check WiFi and by tapping on end you can go back. And this is it, that would be all about advanced service mode
1:26
And if you would like to test your device, if you would like to check some features
1:31
enter my favourite actually code, it is asterisk pound, 0, asterisk pound
1:37
And here we've got the test menu where you can check display, receiver, vibration, touch
1:42
speaker, subkey, front camera and so on. So let me start with display test
1:49
So red is working properly, green also fine, blue perfectly as well
1:56
Then you can check the receiver. As we all can hear, it is working properly
2:06
Then you can check for example simple data, then grip sensor if you want to version S pen
2:16
Let me show you maybe speaker
2:38
So as you can hear, it is definitely working. Now it will be a bit lower
3:01
And click one more time to finish it. And then we can go back
3:06
And that would be all for the test menu. Obviously just pick those features that you want to test and check if they are working
3:11
properly. And another code that you can use in your Samsung is asterisk pound, 1, 2, 3, 4 and
3:19
pound at the end. And here you can check your firmware version, so smoothly enter it and check for example
3:24
the model. And last code, also pretty quick, is asterisk pound 0, asterisk pound 06 pound
3:33
And as you can see, this one will provide you with unique numbers assigned to your device, to your Samsung Galaxy Note 20 Ultra
3:39
And you've got serial number, email numbers and if you click on OK, you'll be back in
3:45
your phone dialer. And this is it. Then you can use your device smoothly in a normal way
3:52
