I’ve been setting up the G6 Plus from Drezha and very nice it is too. In it’s case it’s only fractionally bigger than the G4 but with a larger screen (smaller bezels). The screen quality is very good but not tried it outside yet, nor have I tried the camera but it’s got to be better than the G4. I have a very small Lumix TM70 I use to take photos when travelling so it doesn’t really bother me.
It’s certainly nippy, just waiting for a nano sim from 3 then it’ll be out on the road. Looking forward to Google Pay.
