So for everyone that wants to run the same app side by side, or just two social media accounts, this is a great guide.

LG's software includes exactly the same implementation of Dual Apps (Parallel Apps) as OnePlus. They both work by creating a hidden user on the device and the apps are installed to that user. The only different here is instead of installing the apps to user 999 (OnePlus) the apps need to be installed to user 98 (LG). Plus, LG only supports bad social media apps like Facebook by default.

But we can install any app we want!

Developer Setup:

1. Install 15 Second ADB.

2. Become a developer, and then enable USB debugging. Then change USB mode on the V60 to "MIDI" to connect to debugging.

3. To open ADB on Windows, shift and right click inside the ABD folder. Then click "open in command prompt" or "open in powershell".

App Setup:

1. Get the APK file of what you want to install. I got mine from an APK extractor on my phone.

2. Transfer the APK file to your computer and place it in the ADB install folder.

Installing:

Really simple, just type
Code:
adb install --user 98 test.apk
in the ADB command prompt or powershell.

Final:
Dual Discord
Now you have full access to Dual Apps (Parallel Apps) enjoy your dual accounts, or dual screening.

By the way, I discovered this by opening a Dual App and typing
Code:
adb shell pm list users
. This can probably work for most default Dual App features on phones.

Is the only benefit of this having dual accounts for those apps not natively supported?

I can't see the user case of having two of the same app running side by side, other than Chrome which is already supported

This could be the absolute coolest development for the V60, if I can get it to work. I've been wanting to duplicate the Gallery app, Google Messages, Chrome, a ton of apps that I would enjoy running two instances of, one on each screen. Each time I type the install adb command in I get an "Invalid APK file:" error. Any idea why? Thanks for posting this finding!!

First time using adb, so I'm probably doing something wrong, looks like I was never "connected". Upon authorizing the connection to the PC on my LG, and rerunning the install command, now the cursor just hangs, with no indication that it's doing/has done anything...

Oops, OK so it turns out you just need to let it run for awhile and it will say install success. I tried it with the gallery app, but it didn't seem to do anything. No second install located, doesn't appear in the Dual App list on the phone. Furthermore, when running the adb shell pm list users code, my user number appears to be 13?

Mine succeeded as well, but I also did not see a second app install nor the app listed in the Dual App selection menu from settings.

Before following OP's instructions, you may have to:
1 - first install a stock second app from the LG setting
2 - turn on ADB connection
3 - enter into PC's command prompt: adb shell pm list users
4 - identify the user number (it may be different in every case and may be in the 90s)
5 - follow the rest of the OP's instructions.

The second app should be installed like any other normal app.

Also, note that if you reverse the original second app in above step 1, all manually installed second app(s) may disappear.

Thank you for your help @rest1ess . The key for me was to install a stock LG Dual App first! (I chose WhatsApp since I don't actually use any of the "stock" Dual Apps LG allows). After running 'adb shell pm list users' my user number was actually 97 for the Dual Apps. Installed with success and the second app icon showed up with the Dual App badge on its lower right corner, however I am unable to launch the neither the primary install of the app nor the Dual App install of the app. When I try I get a popup that states: "Installation failed - The app Reddit is missing required components that must be reinstalled from the Google Play Store." and it has 2 buttons: "CLOSE" and "REINSTALL". If I choose to reinstall (whether the Dual App or the main app) it uninstalls and gets rid of both icons at the same time. Any ideas from here?

It seems the problem lies with the app. I too couldn't get it to work with Reddit.

However, if I ADB install with the latest apk from uptodown.com (not with apk extraction), i could get it installed as a dual app, though after i opened both they merged into one instance of the app.

Glad it's not just me... what are the chances the one app I decide to try for a proof of concept is one that doesn't work? lol (I even tried it with same APK filename as what was installed as well as with a renamed filename of the APK that was installed and no dice either way). I can't really think of any other apps I NEED on both screens at the same time... I just wanted to check it out as a proof of concept and familiarize myself with the process.

Just install island from oasis feng from GitHub. It automates the whole process for you and you can even have a separate play store.
