Here I've got Samsung Galaxy A41 and let me show you how to use secret codes on the following device
0:11
So at first you have to open your phone dialer and now we will start with the first code
0:16
which is asterisk pound 06 pound. And as you can see here you've got both email and serial number so if you need to check
0:24
the unique numbers assigned to your Samsung smoothly enter this code and then you will
0:29
be provided with details. Then click on OK to go back and now we will open firmware version

And as you can see here you've got the firmware version so you can smoothly check it and then
0:47
just click on the back button to go back. And now we have to open super useful menu which is the test mode and the code is pretty
0:57
short as it's asterisk pound 0 asterisk pound. And here you can test all the features in your device so you can check the display
1:05
vibration, camera, receiver, speaker, sensor and so on. And for example let me show you the display test
1:13
Click on red to check it and as you can see it is working properly
1:17
Then green. Also good. Blue. Perfect as well. Then if you would like to check vibration just click on vibration and as you can hear
1:28
as I can both feel and hear it is working more than fine
1:32
Then you've got the grip sensor touch. Maybe I will show you the speaker as well
1:43
So we all can hear it clearly it is working properly. And then just pick whatever you would like to test
1:49
Click on it and test the feature. And now we will open another secret mode so just enter asterisk pound 0011 pound
1:59

2:20
your battery enter this code and here you'll be able to check the network, current value
2:25

2:31
And another code that we can use is asterisk pound 0808 pound
2:38
And here you've got the USB settings so here you can change it. If you would like to switch between modes just mark some particular mode
2:46
And that's it. So this is how you can change the USB settings
2:51
Just enter this code and then you've got it. And the last code that you can use is asterisk pound 2663 pound
3:03
And as you can see here we've got the firmware version but it's the advanced one and here
