Review: Great for vacationing. - I bought this specifically for taking my phone on vacation...I accidentally took my old iPhone into the pool while on vacation (killing it of course) last year and didn't want a repeat with the Samsung so I bought this case. The case seems to work well and appears to keep the phone watertight. The screen is clear, the camera appears to be working....audio playback is a little muffled but usable. The only problem I really had was the thumbprint reader, which could have been a mistake on my part. I had a hard time trying to figure out how to apply and ran through all the spares. I contacted the vendor and they were very responsive. I don't plan on using this case every day as I prefer a thinner case and due to the muffled sound and having to remove and replace the plug cover. BTW...it WILL wirelessly charge through the case, although it appears to be a bit slower.
Review: Great construction and lightweight - Excellent case as it's build quality in my opinion is made even better than any high quality phone case like otterbox I've used. It's side grip is very comfortable in your hands and it's very lightweight. As you can see from my picture, I accidentally set it on my stove top for a minute And it melted but still held up. Fortunately thanks to its good construction my camera still works and the case is still usable. 10/10 great job constructing this

## 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: Hello, how can I contact the seller?**

**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.
