Android Dev : surfaceview / thread / canvas

Hello,

I have noticed a slower performance as well on the GPU. My board is a Firefly Rk3288 reload.

My application loads a 1080 texture. Here is the information I could get.

- Firefly-RK3288_Beta_Android4.4_201501271125
    - Average loading time 100ms
    - Driver = OpenGL ES 3.1 v1.r6p0-02rel0.0f4218be5cc66c20a4f31b6cc856ee46
    - GPU : Mali-T760

- FireFly-RK3288-Reload_Android5.1_201603111814
    - Average loading time 11ms
    - Driver = OpenGL ES 3.0
    - GPU = Mali-T764

I think the driver has been updated in the Android 5.1 image. How can I select or re-install the GPU driver used in the 4.4 image? Where to get it from?
