2d sprites not showing up in my 3d game

Hello,

I am not sure, but i know this might be a simple thing I am missing...

So i want to make a 3d mobile game, but with 2d sprites, and i just slowly am building on it... I wanted to check a simple concept and exported the quick game to apk. and got it on my phone... however the sprites dont show up (see screenshot_1.jpg)

its just blank...

BUT if I view it on unity editor... it shows the sprites: screenshot_2.PNG

I installed 2d package which comes with 7 things:
2d animation
2d psd importer
2d sprite
2d sprite shape
2d tile map editor
2d tilemap extras

also installed the mobile package, and not sure what else i need?

using unity version: 2022.2.1f1

thanks in advance

 

K FINALLY found the issue, I put the camera under the player as a child, and i guess that made it an issue to see the sprites, once I put the camera back on the highest part of the object tree... i could see everything fine.
