Here I have LG V30 and let me show you secret code that works on this device
So at the very beginning let me start by using the service menu code
So before I enter this code I need to check out the appropriate information that allows
me choosing the appropriate code for the service menu. Let's open the settings, here let's select general, scroll down and from the general
list you have to choose about phone. So let me tap it, select the hardware info right here and here you need to remember your
model number. So in my case it's LG H930, you need to remember this ending 930
So let me remember that one and now let's go to the home screen, let's open of course
the phone's dialer and let's activate the keypad. And right here you can enter all the secret codes that you know
So as I said let me start by using the service menu. So let's enter the following code, asterix hash 546368 hash asterix and now you have
to enter your model so 930 and hash at the end. That's it, this is the hidden menu when you can navigate by tapping appropriate options
Let's start by using the device test right here. And here you can perform the SAAT right here, SAAT of course
And here you can select some auto tests, so perform all tests, you can perform the manual
test and here for example choose the auto detection item test. As you can see the phone is looking for the SD card, for the battery ID, for the other
important information and item on the phone. If you would like to quit this let's press power key, choose pass or fail
You may perform the ring test for example, let's select pass or fail and other stuff
such as the vibrator, loopback, camera. You may also go back and choose for example service menu optional test, here you can choose
the IDS test and you can also see the test result if you would like to right here

you want. You can also test here the LCD, camera, ringtone, audio, loopback, power on, power off
Let's go back, let me open the SVC menu, here you can check the version of the phone

stuff such as the battery test or for example the motion sensor calibration and the following
features as well. Let's go back, you may also choose the field test and here you can test such things as
browser, modem, WiFi, GPS, Bluetooth, the fake language and SIM info. Let's go back, if you would like to quit the hidden menu, let's use the back arrow a couple
of times and now let me show you another code that works on the LG V30
Let's start by using the testing menu, the Android testing menu. So let's use asterix hash, asterix hash, four six, three six, hash asterix, hash asterix
And as you can see the testing menu pops up, here you can navigate by tapping appropriate
options, let's choose phone information and sometimes you can have access to the phone
info if you have inserted the SIM card, the battery information, when you can read the
battery status, the power plug, battery level, battery scale, battery health and for example
the battery temperature. Let's go back again and choose the usage statistics, here you've got the list of all applications
from your device and you can read such things as the counter or usage time
You may also choose the WiFi information when you can select the WiFi API, here you can
disable network, disconnect network, enable network, get configured networks or get connection info
You may also choose the WiFi status and if you have some WiFi connected to your device
you can read the statistics, you can also refresh your stats or run a ping test
You may also select the WiFi config and here read the information about configured networks
Let's go back couple of times to quit the Android testing menu and this time let's open
the calendar info, so let's use asterix hash, asterix hash, two two five, hash asterix
