Android : "Clear Flags of camera"

I have a question about camera settings.

I want to divide the rendering process as multiple frames and making one rendered image for the purpose of redusing processing load.
In other words, I want to use a cuple of frames to complete one rendering processes.

I assigned a Render Texture for Target Texture of the camera I wanted to use and set as Don’t Clear of Clear Flags setting.

It seems working on PC but not working on Android operated cell-phone which is builded up with Snapdragon chip sets.
The previous frame’s renderd image was corruppted.

Am I missing some settings here?
How can I make it work on Android Phone?

Don’t clear as a camera flag doesn’t work on some mobile devices. If you want a proper solution, please vote for these features:

Thread is very old, however I had this problem and solved it.

I’ve made a Screen Image Effect that reproduces this effect, you can see it here:

Hope this helps!
