Hello Surya,
As you mention, the NXP Android BSP for i.MX7 does not support OpenGL. The Android default browser will invoke chromium webview which can’t work well without OpenGL ES 2.0 support. An alternative would be using other browsers which don’t need OpenGL ES support.
I haven’t tested but it is my understanding that Firefox, QQ and UC Browser can be used without OpenGL.
I hope this information helps!
Regards,
