Here I have Huawei Mate 20 Lite and let me show you how to use secret codes on the following device
0:12
So at the very beginning let's start by using your home screen and let's use the fonts dialer
0:17
Here let's start with the first secret code so let me open the project menu
0:21
Let's use the following code. Asterix hash, asterix hash, two eight, four six five, seven nine, hash asterix, hash asterix
0:35
As you can see the project menu just pops up. Here you can navigate by tapping appropriate options
0:39
You can choose here the background settings and here you can tap background debug and
0:44
make it open. You can change USB port settings and you can switch it into the Google mode, manufacturer
0:51
or HiSuite. You can also use the AP lock and make it open or you can set UI theme color
0:58
Let's go back. You may also tap on venue information and here you can check the version info
1:04
The device is processing data right here. Here you can read the bootloader version, kernel version, AP, CP and other stuff
1:15
You can also choose the other info and read the serial number, run mode
1:20
You can also tap the manufacturer info and you can verify your key
1:26
Let's go back. You can have access also to network information query
1:30
Here you've got two interesting things. The simlog info and you can check the simlog status, the vendor country info
1:42
Your vendor and your country. Let's tap close. Let's go back. You can also choose the software upgrade and you can upgrade your device by using the SD card
1:53
You can accomplish the hard reset by choosing restore factory but let's just be careful
1:57
with that operation because you will lose all your data. And you can also choose the battery charge and see the battery temperature and the battery level
2:05
Alright, let's go back to quit the project menu and now let me check out the second secret code
2:12
So let's open the about phone options. Let's use asterisk hash, asterisk hash, 0000, hash asterisk, hash asterisk
2:24

2:55
