works well
got a lot less "crap" on it than your normal big carrier phone. its Very fast. 2 cameras, pictures fine, but best thing is the cameras can do a lot of things- timelapse, zoom, all sorts of stuff and has a led flash/flood.camera ,and apparently everything else, works under water
If you get one of these, get a 64gig fast mem chip also, as it lets you store the data from most of your programs on the chip, instead of using your internal mem.
Thing takes go pro like vids with ease. has both current gps systems and i loaded up the US topo program to figure out where I am when off exploring on all the trails round here. so far, no negs to me. sound is good and loud.
