According to the specs this has dual layer glass plus a metal rim and rubber back cover. Would getting screen protector be wise or forget it since it's dual layer.
I haven't used a case on the g4 and recently took the glass protector off. I'm just kinda burned out on buying them for every phone every six months or so. I jump to a new phone and end up with a handful of stuff I no longer need.
Heck, I got a brand new T-Mobile leather back, 3 extra batteries and chargers for the g4 that'll be no use within a month. I didn't buy them, but imagine if I would've bought the normal 3-4 cases to find the right one along with this stuff.
I had Verizon put their version of tempered glass on when I bought it. I'm a big Zagg fan, but this one is super clear and the screen absolutely pops with it on. So many comments about it. Can't even tell it's there.
