then do not cheat the buyers by saying they have the support on this phone. or at least put up until what software version arrives support! this is called seriousness!

diffusore1976 · 02-28-2019, 15:27

have many new things, but not working, in my opinion it's like not having them !! now the z3x support died together with the box !!

Ok. You can make own box and research new LG security

I think that there are people paid to find new security exploits for the firmware for this box. I am not a developer! Because if buyers have to do the developers as well, we are really bad!

This isn't easy find new bug. We research 3 month. LG make fully new security.
