2. LG Stylo 3 Plus Dialer Code to Enter “Phone Testing Menu”
The Testing menu is found on most of the GSM Android phones.
The dialer code to enter testing menu is *#*#4636#*#*
Make sure you add * in the end. It’s not shown in the screenshot above.
There are 4 options in the testing Menu as shown above.
The first one is “Phone Information”. This is disabled in Stylo 3 Plus. It basically allows us changing the network mode. It throws an error “This application does not work on this device”.
Next is the Battery Information.
This same option was found in the Hidden Menu with the same Battery Information.
The 3rd option in the Testing menu is “Usage Statistics”.
It keeps a Tab on the App usage time and when was it used the last time.
This data gets erased with a factory data reset.
The last option in the “Testing Menu” is Wifi Information.
It’s similar to one found in the Hidden Menu.
The first option under Wifi Information is Wifi API.
“Wifi config” logs data regarding the previously Configured Wifi networks.
Wifi status includes a ping test and can help in troubleshooting Wifi connection problems.
3. LG Stylo 3 Plus Dialer Code to check IMEI
*#06# is the universal code for checking the IMEI and works on almost every GSM phone.
IMEI can also be checked under the battery or within the phone settings however the quickest and most reliable method is by using the dialer code *#06#
If you would turn OFF your LG Stylo 3 Plus and Press Volume UP + Volume Down + Power, to turn it ON a white screen would appear showing the Serial number and IMEI number of your device.

I have the MP450 as well as the TP 450. Now both are rooted, and I installed an app I purchased back when I had Samsung devices…Phone Info + …. It shows dialer codes that normal hidden menu dialers don’t show… Like this one called United Debug Tool. Or the LPP runtime editor…these are some of the most revealing and can be dangerous to alter if a person doesn’t know what they are doing. Perhaps you could shed some light on these for us??? I especially am curious about the United Debug Tool and the password required to access that APN settings in that area
What program or app did you use to root your mp450?
