Fortnite for LG K20 Plus Download / Is Fortnite compatible with LG K20 ?

The minimum recommended system requirements for Fortnite Mobile are 2GB RAM, Android Oreo, and OpenGL 3.x 3D graphics support.

In this post, we’re going to test out the official version as well as the modded apk of Fortnite game on LG K20 Plus. So, Let’s check out whether Fornite is compatible with LG K20 or not

First Lets’ install the Fortnite apk from the official web page as follows –


Can you Play Fortnite on LG K20 Plus ?

Before installation, we need to enable installation from “Unknown Sources”.

To do this, Go to Settings < Fingerprint & security < Unknown sources and tap on it to enable it


Now I’m using Google Chrome browser to download fortnite from the official website.

We’ve to download the Fortnite installer

I’ve downloaded the “EpicGamesApp.apk” file as shown above

Now Let’s install the apk file

I’m launching the Fortnite installer app

The installer says “DEVICE NOT SUPPORTED”.

The recommended system requirements for Fortnite are Android 8.0 or higher with 64-bit architecture

So, let’s try to install the modded Fortnite apk which requires 64-bit Android OS.



LG K20 Plus Fortnite Modded APK Installation

I’ve flashed Lineage OS 15 custom ROM on LG K20 Plus which is 64-bit ROM running on Android Oreo 8.1.0

Let’s download and install the modded Fortnite apk file as shown above



After the installation is done, tap “OPEN” to run the installer app

The installer is  loading

Bad News!  The 3D graphics requirement are not met.

Fortnite requires at least OpenGL ES 3.1 3D graphics support but K20 Plus has OpenGL ES 2.0 so it cannot run Fornite.

Moreover, it throws an error that the  Texture Format is also Unsupported as shown above.


So, don’t waste your time installing Fortnite on K20 Plus. It doesn’t have the necessary hardware to run Fornite.
