Hi everyone, in front of me I've got a Samsung Galaxy A13 and let me share with you how to
0:12
use secret codes on this device. So first of all let's open the dialer because this is the place where we will enter all
0:19
of those codes and let me begin with the shortest one and I really think that it's the most
0:25
interesting one. So the code is O** and as you can see thanks to this code we can enter the testing mode
0:34
so here we can check all of the components of our device. So for example we can check the screen by tapping on red and we can check if the screen
0:43
is working perfectly fine so if you cannot find any missing spots like white dots or
0:49
something like that then it means that for sure everything is ok
0:54
And the same situation with the blue and the green one. For example we can check also the touch option so as you can see here we've got some rectangles
1:03
and squares or only rectangles and we have to draw the lines all across them in order
1:10
to check if the edges of our device, if the edges of the screen are working
1:15
So if you can see the green colour after drawing a line it means that it is working
1:20
So if we will draw the line all across all of them the device will automatically go back
1:26
to the previous menu which means that for sure the touch option is working so I really
1:32
highly recommend to stay here and have fun with this section because not only you can
1:37
have fun but also you can check your device. So if you'd like to get back you have to let's say double tap or just double this gesture
1:47
So let me show you another code which will open the e-mail info and it is asterisk pound
1:52
oh six pound. And as you can see by this code we are provided with both e-mail numbers and also a serial
1:59
number attached to this device. So let me tap on OK and let me show you another code which will open the battery status and
2:08
it is asterisk pound oh double eight pound. And as I said we are in the battery status so here we can check the current value for
2:16
example the level block or the voltage. Let's get back and let me show you another code which will open the USB settings and
2:25
the code is asterisk pound oh eight oh eight pound. And as I said we are in the USB settings here we've got two different modes from which we
2:34
can choose. If you want to change the mode just tap on the other one and tap on OK
2:40
You can of course tap on reboot and your device will be simply restarted
2:45
So let me get back and let me show you another code which will open the firmware version
2:51
and the code is asterisk pound one two three four pound. And as I said we are in the shortened mode version so here we've got the AP, CP or the
3:02
model of our device. So let me get back and let me show you advanced firmware version and the code for it is asterisk
3:11
pound two double six three pound. And as I said we've got let's say the extended version of the firmware so here we can check
3:21
some technical details so for example the sensor hub we've got the Wi-Fi version of
3:26
course here. Now we can check some details we've got also the Bluetooth version and we can refresh the
3:31
Wi-Fi version. So let me get back and let me show you the last code which will open the service mode
3:38
and the code is asterisk pound double oh double one pound. And as I said we are in the service mode
3:47
So basically that's all this is how to use secret codes in your Samsung Galaxy A13
