I've always used tempered glass screen protectors that directly sticks onto the display. They are oleophobic and cause no issues with touch sensitivity. Also, when applied properly, dust does not get underneath.

With cases that have built-in screen protectors, I don't see how they can form a perfect bond and seal with the phone (or do they?), so I would imagine dust can get underneath? Also, from the videos I have seen, they tend to show a lot of glare and fingerprint.

Can folks share your experiences with cases that have the built-in screen protector, especially when compared to the directly-applied protectors?

Thanks.
