Overview
A few months ago I purchased the Nodus Access Case for my iPhone 6 Plus. The case feels very high quality and offers very good protection for the phone. And since it's leather, it smells awesome.
For those not familiar with the Nodus Access Case, the case closes by using a small micro suction pad that attaches itself to the iPhone's screen. As the name implies, micro suction is not an adhesive but a small piece of material made of tiny microscopic suction bits that attach themselves to a surface. There is also another larger micro suction pad on the right side of the case that attaches itself to the back of the iPhone. The grip is surprisingly strong and the phone never become detached from the case. You can shake the devil out of it and the phone will remain stuck to the case. Very impressive!
One issue with the small micro suction pad is that it tends to attract dust and lose its sticking strength so Nodus recommends that you take a damp microfiber cloth and gently wipe the pad to make it work as intended again. Not a big deal and it works quite well afterwards. If for some reason the pad is not working as intended, you can shoot them and email and they will happily send you replacement pads for your case.
Big Problem
A couple of weeks ago, I had to stop using my case because the front pad was no longer sticking so I waiting on my replacement pads to arrive. This is when I noticed a big issue: The front micro suction pad on the Access Case had stripped my iPhone's oleophobic coating.
The trouble area is exactly the shape of the pad and it is very difficult to wipe clean. I would notice the pad imprint on the display before, but I would just sort of wipe it with my finger and forget about it. If I use a bit more force, I can wipe the spot clean but it returns as soon as there is oil/smudges in that spot even without the case present.
Customer Service
I emailed Nodus Customer Service and, in short, they told me it was my fault.
First reply. They claim I used cleaning solutions on my screen:
I've never used cleaning solutions on my iPhone. However, had I used a cleaning solution I'm certain that the affected area would be a lot larger and not in the shape of their micro suction pad. I explained this to the CS representative. Their new reply was now that it was not cleaning solutions used on my iPhone but finger grease that could be wiped away.
Please keep in mind that I haven't used the case in two weeks. I would imagine that any transfer residue from the pad to the display would have been wiped away by now by new smudges. Also if I was allegedly using cleaning solutions on my iPhone, you would think there wouldn't be any grease residue from the pad at all.
Conclusion
This was my favorite case for any phone I've had by far, so it saddens me that it was ruined by a very big design oversight and poor customer service. I guess the silver lining in all this is that they agreed to refund me for the case after I return it.
I wanted to post this here because this is where I discovered the Nodus Access Case and wouldn't want anyone else to ruin their phone with this case. If you have this case, you can check to see if this issue has affected you. Wipe your screen completely then shine a light on the spot where the micro suction pad rested. You can also smudge your phone a bit on the spot and you should see the pad shape return.
This was my first post! I hope it was informative. Thanks for reading.

Please excuse the potato quality pictures. My iPhone is my only good camera.

Thank you for your email and for supplying the images to us. We are very sorry that you have experienced this problem. We do not advise using cleaning solutions on iPhone screens as it speeds up the breakdown of the oleophobic coating on the screen, and therefore we recommend to only use a dry or damp microfiber cloth. If there is currently any residue on your screen this should clean off without a problem using this method . The oleophobic coating does start to wear off naturally anyway.

Thank you for coming back to me. We do understand that you are concerned regarding your screen. However, it does appear that the mark on your screen where the micro suction pad sits is purely grease/oil from your fingers that has been left on the microsuction tab and transferred to the screen.
