Screen and loud speaker issues!

I replaced the broken plates on my iPhone, front and back. I've got two issues:

1-The screen now has a white glow around the edges, not terrible but noticeable. How do I resolve this?

2-Prior to installing, the loud speaker stopped working, for use with speaker phone and listening to music (without earphones). I thought replacing the faceplate would correct this but it did not. The original damaged portion was at the ear speaker next to front facing camera, which is why I replaced the front plate. I'm thinking the issue is the speakers at bottom, is there any way to troubleshoot?

Thanks all!
