I come across the Low 2D graphics performance the same as this. After searching, I found a most possible solution at here. It is a patch for Android L5.0.0_1.0.0 that update GPU driver from 5.0.11p4 to 5.0.11p8 (as well as .so). However, this link contains only 2 documents. How can I get that patch?
Android OS for i.MX Applications Processors only provides resources from 6.0.1+ and provides no archived resources. 2D graphic on imx 6 Android L 5.x is very slow. I just can't update my whole system. Any help is welcome.
