Hi everyone, in front of me I've got Samsung Galaxy M13 and let me share with you how to
0:11
use secret codes on this device. So first of all let's open the dialer as it is the place where we can enter all those
0:18
codes and let me begin with the shortest one and in my personal opinion the most interesting one
0:25
So the code is asterisk bound, O asterisk bound, yes. So right here we've been transferred to the testing mode
0:34
So here we can check some components of our device, so for example the screen, the vibration
0:42
the receiver, sensor, touch, speaker, version and so on. So let me show you how it works
0:48
Let's tap on red and as you can see we've got this bright red all across the screen
0:54
and if you can see it everywhere without any missing spots like white dots or black dots
1:00
it then it means that your screen works perfectly fine. The same situation with the green and the blue so if you can see it all across the screen
1:09
then your device is in perfect condition, at least the screen. So here we've got the touch for example and here we have to draw the lines across those
1:19
rectangles here on the edges of the screen and thanks to this if you can, if you draw
1:25
the line and you can see that the square or the rectangle changes the color to this bright
1:31
green it means that the touch in this place works perfectly fine
1:36
So as you can see it is working. Let me draw this line also
1:42
Alright and if you'll pass the test you will just come back to this section
1:47
So I highly recommend to stick, I mean to stay in this mode and just have fun with your
1:53
device and at the same time check the components of it. So double back to get back and let me show you another code which will open the email
2:05
number, email info. So the code is asterisk pound 06 pound and as you can see thanks to this code we are
2:12
provided with both email numbers and also a serial number attached to this device
2:18
So let me tap on OK and let me show you another code which will open the battery status and
2:23
the code for it is asterisk pound 0228 pound. And as I said we are in the battery status so here we can check for example the voltage
2:35
current level, level blocks or the current CHG. So let's get back and let me show you another code which will open the USB settings and
2:46
the code for it is asterisk pound 0808 pound. And here we've got two different modes of the USB, we've got MTP option currently applied
2:56
If you'd like to set the other option just tap on it, make sure that it is marked and
3:00
tap on OK. Of course after tapping on reboot your device will be restarted
3:05
So now let me show you the code which is probably the easiest to remember
3:11
So the code is asterisk pound 1234 pound. And here we can check the version so technical info about our device so APCP and the model
3:22
Let's get back and let's open another firmware version and the code for it is asterisk pound
3:28
2663 pound. And as I said here we've got the advanced firmware version let's say so here we've got
3:36
also a lot of technical info so we've got for example the Wi-Fi version, we've got the
3:41
sensor hub or we can check some info about the Bluetooth version
3:47
So let me get back and let me show you and it will be the last code how to enter the
3:52
service mode and the code for it is asterisk pound 0011 pound
3:59
And this is how to enter the service mode. So actually this is it this is how to use secret codes in your Samsung Galaxy M13
