Quality on mobile phones is very low!

I work on a project and upload the model in glb format. On the PC everything renders fine. The quality is quite good. But when I tested it on the phone, the quality was very low. Can anyone tell me some solutions to fix it or not? Thank you very much!

it’s pretty difficult to tell what the problem is without seeing some code…

have you set your renderers pixel ratio to the device pixel ratio?

renderer.setPixelRatio( window.devicePixelRatio );
