Don't use video camera too much mate, but there is HD, FHD and UHD in the video camera settings. UHD says 3840 x 2160. I'm with amaysim which uses the Optus network. No problems so far.
Has anyone successfully flashed a stock marshmallow KDZ to their phone?
If you did, how and which region kdz did you download please?
I used this guide for 30B kdz: http://forum.xda-developers.com/lg-g3/general/lg-g3-android-mars...
