Here I have Samsung Galaxy J3 Prime and let me show you how to use secret codes on the
0:10
following device. So at the very beginning let's open the phone's dialer, let's activate the keypad and let's
0:16
use the first secret code so let me check the main version of the device
0:21
Let's use this code asterix hash 12580 star 369 hash
0:32
As you can see the main version just pops up, here you can read the AP, CP, CSC and
0:38
other important stuff. So let me go back, now it's time to check the test mode
0:45
Let's use this code asterix hash 7353 and hash. As you can see the test mode pops up, here you can navigate by tapping appropriate options
0:55
and you can test all hardware features such as the melody, vibration, speaker, dimming
1:05
and other stuff such as camera, front camera, bluetooth, dot mode and sensors
1:10
Let's go back, now let's open another testing menu, so let's use asterix hash 0 asterix
1:19
hash and as you can see the following menu pops up, here you can test the colors of the
1:24
screen, the red, green, blue, you may test the receiver, also vibration and other stuff
1:32
such as the sensor, touch, subkey, speaker, flow frequency and a lot of more
1:37
Let's go back, so here you can also check the service mode, let me just quit the testing menu
1:47
Alright let's open the service mode by inputting asterix hash 0011 hash
1:57
Service mode pops up, here you can use more key and use this options or read the following specification
2:03
Let me quit the service mode, this time let's open the advanced service menu, sometimes
2:09
this code works on your device, let's check it. Let's input asterix hash 2683662 and hash
2:23
As you can see this is the advanced service mode. Alright you can also go back, let's check out the battery status mode, let's input asterix
2:33
hash 0228 and hash. Here you've got the battery status, you can read a couple of useful information about
2:41
your battery. Let's go back, now let's open the USB settings mode, so let's input asterix hash 0808 and hash
2:53
The USB settings pops up, here you can change some modes of your USB and you can also check
3:01
the advanced firmware version, let's use asterix hash 2663 and hash
3:10
So this is the firmware version of your device, let me go back and let's check the camera
3:17
firmware standard, so let's use the following code asterix hash 7412345, sorry 2365 and star
3:38
Seems this code works so it's worth to check if it's correct, let me just choose the following
3:45
one, alright, so this device doesn't support the camera firmware checking. And also at the end let me show you how to check the email number by using the secret
3:56
code so you need to use asterix hash 06 hash and the email number just pops up in front
4:01
