Weird rendering when I package game for android

Hi everyone, I am experiencing a weird issue when i package my game for android,
I have attached two images to that effect.
The rendering changes when I move withing the game. This is happening only in specific rooms.

In one of the images, the rendering it okay and when I move just a little distance or turn the camera away, it gets better. What could be causing this?

I have tested on a galaxy s6 edge and a Samsung J7 Prime still same
I have packaged for ETC1, ETC1a and ETC2 still same
