LG V20 Case, Ringke [Fusion] Clear PC Back TPU Bumper [Drop Protection/Shock Absorption Technology] Raised Bezels Protective Cover for LG V20 2016 - Clear https://www.amazon.com/dp/B01K5I9CJQ/ref=cm_sw_r_cp_apa_jup8zb60QPTZJ
Used this one for months, many drops on concrete with any signs of damage to my phone. Super easy to remove, just thick enough to protect the camera lense, and you can put a photo behind the clear back to "customize" your phone.
Just received this case yesterday. Got it in 3 days (free shipping from amazon). I like it so far. The case is very clear and comes with protective "layers" that are peeled off to keep it looking clear after it is shipped to you. The camera hump and front screen are protected as the case comes slightly above the phone itself. All ports are accounted for. The headphone jack and charging port have pretty open cutouts but anything overly large may be a slight issue. It's not really any smaller than any other case though so this doesn't really take anything away from this case. I purchased a dbrand front/back/camera skin that is on it's way, so i'll update you on whether or not I continue to use the case with the skin... Also a screen protector that doesn't come all the way to the sides of the screen may get lifted up by this case when you squeeze the sides, further info once I get a tempered and non tempered screen protector (on the way)to test this out.
If it starts to make you crazy, take a look at this one:

Very thin as well.
