Android Project packaging doubts

ok i packed default TPP template for android ATC because my phone has adreno graphics card so when i run that packed project in my android device having adreno 506 graphics is showing texture like attached picture so what settings do i need to do in order to achieve normal quality or even better

my phones specs:
Qualcomm Snapdragon 625
adreno 506
4GB ram

also when i tested it with ETC 2 then it shows fine quality same as the PC editors
