Here I've got Samsung Galaxy Fold and let me show you some of the secret codes that
0:10
you can use on this device. So to enter a secret code you have to open the phone dialer and once you see the keypad
0:18
we can start entering the code. So let's start with the shortest one, it's asterisk pound or six pound
0:25
And as you can see this one will provide you with unique numbers assigned to your Samsung Galaxy Fold and for example is our email number or serial number
0:33
Then just click on OK to go back. So if you need to locate the unique numbers assigned to your phone to your Samsung smoothly
0:40
enter the code which is asterisk pound or six pound and immediately after that you will
0:45
be provided with the detailed info. Then the second code is asterisk pound, double O, double one, pound
0:55
And as you can see now we are in service mode so here you can check service information
1:00
If you click on the more icon you will be able to use some further details, to use some
1:05
further options. So for example you can pick help to gain some further knowledge and if you click on back
1:11
you'll be back here. So this is it, that will be all for this code
1:16
And another one is asterisk pound, O8, O8 and pound at the end
1:24
And here you've got the USB settings and if you would like to change the setup of your
1:28
USB cable smoothly click here and mark the one that you would like to apply, then click
1:33
on OK and it is saved. Then to change it again you have to enter the same code one more time and let's go back
1:40
to the previous setup. Tap on OK and this is it. So that will be all for USB setting and now let's enter asterisk pound, 1, 2, 3, 4 and
1:52
pound at the end. And here you've got your software version so smoothly enter this code and get detailed
1:58
information about your device's version. So that would be all. These are the codes that you can use on your Samsung Galaxy Fold
2:06
Enjoy them and use them. OK, now we have one more. Let me go back
2:11
Super useful one, I forgot about it and it's asterisk pound, O asterisk pound
2:18
Actually that was the best one. I wanted to have it at the end so this is it
2:23
And this one will help you to test your device to test features that you can use on your
2:28
Samsung Galaxy Fold. And let me start with display test. So here you can check the colors if they are working properly
2:35
As you can see both red and green are working just fine
2:39
Blue is also working correctly, then black also good. To turn off black you have to click on the power key
2:47
And then we can check receiver. As we all can hear it's working as it should
2:56
Then vibration also perfect. You can also check the camera, grip sensor, sensor touch, touchsap, speakers so let me
3:06
also test the speakers. This is the left speaker and then the right one
3:15
Let me test it. And it is also working good. And just pick the feature that you would like to test, click on it and then check if it's
3:26
working good, if it's working properly. So this is it, that would be all
3:30
Now we definitely finished with the code so that was the last one
3:35
