Here we've got Samsung Galaxy A12 and let me show you some of the secret codes that
0:11
you can use in this device. So once you want to enter any of hidden panels here, you need to open your phone dealer at
0:18
first because this is the place where we'll be entering those codes
0:23
And let's start with the first code, one from the most useful, and it is asterisk
0:30
pound 06 pound. This is the shortcode, so smoothly enter asterisk pound 06 pound and you will be provided with
0:37
unique numbers assigned to your Galaxy A12, which are email and serial numbers
0:42
To close this panel, just tap on OK and that's it. So let's skip to the second code, which will provide us with firmware version
0:52
This is also pretty easy code because it's asterisk pound 1234 and pound at the end
0:59
And as you can see here, you can check your firmware version. It's right in front of you
1:03
So that's basically all. Let me go back. Now we will open test mode, my favorite panel, and the code is asterisk pound 0 asterisk pound
1:14
And here you can test your device. So if you have any issues, you can smoothly detect if it's about your phone or app itself
1:22
And for example, let me check the display. So red color is working properly. Green
1:32
Perfect as well. Blue. Also good. Then you can check receiver. So we can hear clearly that it's working
1:42
Also the vibration. You can hear it. I can both hear and feel it
1:46
It is working properly. Then you can check mega cam, grip sensor, sensor, touch, speaker, sub key, front cam
1:52
black display, and also version. So just pick the feature that you'd like to test, that you'd like to check, and it will
1:58
be provided with the info, with details. So let me go back
2:02
That would be all for test mode. And now we will open advanced service mode
2:07
To do it, you just need to enter a code, asterisk pound, 2683662, and pound at the end
2:17
And here you've got service mode, so you can smoothly reach this panel with this quite
2:22
long code. Let me go back. And now we can detect the battery status
2:27
To do it, it's time to enter asterisk pound, 0228, pound at the end
2:35
And here we've got the battery status. Here we've got all info. You can also enable quick start here, and just check average value, current value, and
2:43
so on. Let me go back then. And if you'd like to change the USB settings in your phone, you need to enter asterisk
2:51
pound, 0808, and pound at the end. And here you can check the setup for your USB, smoothly mark the one that you'd like
3:00
to apply, and it will be changed this way. So this is it
3:05
This is how you can reach USB setup. And the last code that I would like to share with you today is advanced firmware version
3:13
To reach this panel, you need to enter asterisk pound, 2663, and pound at the end
3:21
And as you can see here, you've got the advanced firmware version, so you can read way more
3:27
details than previously with this code, 1234. And this is it. These are all codes that I wanted to share with you today
3:35
Use them whenever you need to, as often as you want to. Thank you for watching
