I got this one and it comes with a screen protector as well. http://www.amazon.com/LG-Case-COMPATIBLE-Protection-Absorption/dp/B00V51QOXA/ref=pd_sxp_grid_pt_0_0
Otterbox Defender will work it is a snug fit so just snap the shell together one at a time but I do have a temper glass protector on it and removed the Plastic protector the case comes with. Wireless Charging does work for me.
Supcases - Unicorn Beetle and the Water Resistant ( better prices on Amazon and you can find the Water R on eBay for $12.xx or less shipped)
http://www.supcase.com/lg-g4-cases.html
The Unicorn Beetle comes with the belt clip and the Water R does not. You can use the belt clip on the Water R case it works fine even though Supcase will say no and you can't buy the belt clip anywhere you have to buy the Unicorn Beetle case to get it. Wireless charging works as well. Even though the Unicorn Beetle fits the Leather it's not 100% or atleast on mine the rubber shell that locks over the plastic face if you would slide your finger off the side of the case it started to come undone like I was trying to take apart the case. If you had a Otterbox Defender you might get what I'm saying how they grove on the plastic shell and the rubber lock in. I did try the Beetle with no back cover and did not have this issue. The Water R does not have this issue.
Ringke FUSION Clear (Revised Case) I have as well works fine just make sure the camera cutout looks like the one here.
Also got this one. It's a little hard to get off and want to pop the Leather back off usually as well.
Here's the one I'm getting, clear so you can still see the leather
