The problem is that Android devices are competing with each other. Must unite characteristics by company NVIDIA and Google and selling a larger amount so that developers can rely on the specific characteristics.
That’s even more unlikely…
However, just as Metal is pushing iOS (and making Android step up its game), the ES 3.1 + AEP extension pack for newer devices is a nice compromise!
That’s only good for processing performance. There was no indication that it will also include a graphic enhancement. Apple will also take this pleasure to include the 7XT to their upcoming new ipad air 3.
There are too many GPU vendors in Android ecosystem, its not a clear cut evolution like it was for Apple.
The problem with Android is that it cannot update the GPU firmware easily. Android 4.4 included an update to Play Store to update firmware but nothing seems to have come of it. No quick patches for SSL,… exploits nor to fix graphics driver bugs. Maybe late version of 5 or in Android 6 there will be better support to fix graphics driver bugs and make OpenGL functionality available. Right now you get a monolithic device, bugs and all for a couple years.
NVidia Shield tablet is exception, but its a dedicated gaming device.
