## Questions & Answers

**Q: Does fingerprint unlocking still work after installing the phone case?**
A: Not on my phone.  I purchased one case (identical to this one) and couldn't get it to work.  Read instruction and followed them to a T on this one and the fingerprint scanner still won't register a fingerprint.  I even turned screen sensitivity to max.

**Q: Are either of the cameras blurry when taking photos?**
A: I love the case and it does pretty well for most situations. However the material that covers the lens depending on how much sun is shining into it causes some glare in the picture. I checked by taking the case off and it was fine and the amount of light being distorted was gone. Not sure if it's the phone specifically or just camera lens protectors but no matter what, the focus on up close items struggles a bit. The front facing one However I didn't have any issues as of yet.

**Q: Help! What is the purpose of the product insert with 3 yellow pull tabs? It looks like it is for the 3 cameras but aren’t those already protected?**
A: They're extra fingerprint 'dots' in case you need to replace the one that came on the case.
