Hi, There you can download APK file "OpenGL ES 2.0 " for Android free, apk file version is 1.23 to download to your android device just click this button. It's easy and warranty. We provide only original apk files. If any of materials on this site violates your rights, report us
Please download the refreshed version of this app called "GPU Pixel Shaders OGL Demo" that you can find scrolling down a little bit, not this one because it DOES NOT work properly in latest android versions and it cannot be updated because of the latest google policy regarding the use of the OpenGL term/mark.
Despite the many 1 stars reviews for not working in many devices for reasons not related to the app itself, thanks to everyone for the comments and I hope the new app works fine in every device.
