Our apologies for any confusion regarding the screenless design of the Defender Series for the Galaxy Note10+. We try to be as transparent as possible on our Amazon product pages with a declaration in the title with states "screenless," as well as having it mentioned again in the bullet-points that there is no screen protector included, so it’s certainly disappointing to hear that there was some misunderstanding nonetheless.
This was actually a design shift that was implemented with the advent of Samsung's Infinity Screen upon the release of the Galaxy S8. After extensive testing and consideration, we genuinely felt that the best balance between protection and the performance people would rightly expect from the expansive and curved touchscreens was to allow for direct interaction while still leaving open the option for use with a separate screen protector such as the OtterBox Alpha Glass or OtterBox Alpha Flex, depending on which device is being covered.
Although not exactly as you anticipated, we do hope that you still get great use and enjoyment from the case, and if we can be of any further Otter assistance, please don't hesitate to give us a quick call at 1-855-688-7269, and we'll always be happy to help!
