YooTech Tempered Glass
YooTech is a relatively new brand that offers a slim yet durable screen protector for the LG G4. It's the same tempered and hardened glass as many good screen guards, but comes in thinner at just .2mm instead of .33 like a few others mentioned here today.
It's also under $7, comes with a lifetime warranty, and they've rounded the edges and corners for a more comfortable experience so swiping the screen is smooth and natural, without rough edges.
