camera – Why do my mobile phone images have a ghostly glow?

I’m not too sure if a setting or update has changed the quality of my photos, or if the glass lens protector I have put on may be causing this.

I have a Samsung S10 5G. It used to take amazing photos, however for ages now there is a glow around the edges or near bright colors, they kind of bleed into the surroundings.

Here is an old photo; around this time all images had a similar clear kind of quality:

However, now all my phone images have this strange glow similar to this image below, and it makes the images look terrible! I have tried resetting the camera settings and this doesn’t seem to help.

This is the camera protector I have. I’m not too sure if the quality of glass may be causing the light to bounce around before it hits the sensor?

Any ideas?
