Here I have LG Q4 2017 and let me show you how to use secret codes on the following device
0:11
So at the very beginning let's start by using a home screen. Find and select the phone icon right here, let's activate a phone's dialer and let's
0:19
input the following secret code. So let's start by using the testing menu
0:23
Let me use star hash, star hash, 4636, hash star, hash star
0:35
As you can see testing menu just pops up in front of you. Here you can navigate by tapping appropriate options
0:39
So let's choose phone information first. And here you've got all statistics about your device
0:45
You may also choose battery information to check the battery status, power plug, battery
0:49
level, battery scale, battery health, time since boot and other statistics. Let's go back
0:55
Let's choose user statistics and here you've got the stats about the application from your
0:59
device and you can read such things as count and usage time
1:04
Let's go back and choose WiFi information, here you can select WiFi API, when you can
1:08
disable network, disconnect network, enable network, get configured networks or get connection info
1:14
Let's go back. Let's choose WiFi config and if you have some configured networks here you should find
1:19
the full specification about them. Let's go back again and choose WiFi status, here you've got the statistics about your
1:26
WiFi and you can refresh all stats or run a ping test
1:30
Let's go back a couple of times just to quit the testing menu and this time let's open
1:34
the calendar info. So let's use star hash, star hash, 225, hash star, hash star
1:43
As you can see calendar info just pops up, so here you've got all statistics about your calendar
1:48
Let's go back. This time let's open Google Play services, so let's use star hash, star hash, 426, hash
1:59
star, hash star and the Google Play services mode just pops up
2:04
So let's go back and let's open debug UI, let's use star hash, star hash, 759, hash
2:11
star, hash star. As you can see debug UI just pops up, here you can view client's IDs, choose pings or
2:18
change the OEM mode. And at the end let me show you how to check email number by using a secret code
2:25
Let's use star hash, 06 hash and the email number just pops up
2:31
Let's tap OK to close this window. So that's it, everything went well
