Hi everyone, here we've got Samsung Galaxy A02s and let me show you how to use secret
0:12
codes on this device. So first of all we have to open the dialer, because this is the place where we'll enter
0:17
all of those codes. And let me show you the very first code which is asterisk bound, 06 bound
0:25
And as you can see by this code we are provided with both e-mail numbers and also a serial
0:29
number attached to this device. Let's tap on OK and let me show you another code which is the easiest one
0:36
It's asterisk bound, 1234 bound. And thanks to this code we can check the version of this device, so we can check the AP and
0:45
CP number and also the model. Let's get back and let me show you another code which is the shortest one and I think
0:52
the most useful. So it's asterisk bound, 0 asterisk bound. And as you can see here we've got the testing mode, so here we can check the components
1:01
of our device. So we can check for example the screen, sensor, touch, speaker, the front camera, the grip
1:07
sensor, loopback, actually a lot of options to check and test. And let me show you how to test for example the screen, so simply tap on red
1:16
And if you can see the red all across the screen without any missing spots, then it
1:21
means that the screen works perfectly fine. So let's tap on it and check the green, the same situation, blue, blue works fine also
1:30
And let's check for example the vibrations, so simply tap on vibration
1:34
And if you can feel and hear the vibration then it means that it works fine
1:39
So let's tap on it. So actually that's all for this code, so I highly recommend to stay here and actually
1:47
have fun with your device. Now let me get back to the dialer and let me show you another code which is asterisk
1:54
bound, 0228 bound. And as you can see here we can check the battery status, so here we've got some info like the
2:02
voltage, level, level block, or we can check the average value. What's more here we've got also notificated charging type, if you are charging your device
2:12
at this moment. Let me get back and let me show you another code which is asterisk bound, 0808 bound
2:21
And here we've got the USB settings and modes and here you can actually change it, just
2:29
find the option you'd like to use and tap on it, make sure that it is marked like here
2:34
And to confirm just tap on OK or reboot, then your device will simply restart
2:40
But let me leave it like this. And now let me show you the last code which is asterisk bound, 2663 bound
2:51
And here we've got the firmware version, so here you can check the WiFi version, for example
2:57
Bluetooth version and the TSP threshold. So actually that's all. This is how to use secret codes in your Samsung Galaxy A02s
