Well I have to say I am amazed by the upscreen Reflection Shield Matte Premium Screen Protector for DJI Smart Controller. Like everyone I suppose I was concerned about the effect of the touch sensitivity. When I received my SC I wasn't totally impressed with the touch sensitivity to the point where I wondered if there was a setting to increase it. (which of course there isn't) Also I have a Crystalsky Ultra which seemed more sensitive. Anyway I purchased the above protector which comes from Germany and as incredible as it sounds it seems to make the touch more sensitive with the added bonus of being less reflective and a very nice touch surface. I have also fitted one on my Crystalsky and Samsung Galaxy A51 with the same results.
