I used V60 with dual screen before for 3 months+. Yes I like the extra screen very much. Since v50 I use it with dual screen. I sold my V60 to test the Wing but unfortunately the second screen is too small and I had to let go mine after few weeks.

Im waiting for V70, surely the dual screen can do much more now.

Never try G8X.
Typing on dual screen is great, just rotate it to landscape mode and you get a bigger full screen keyboard

Yes. The dual screen is major factor i bought LG phone. While Wing is for test only, the gimbal is very good but limited to fullHD recording only. For Velvet really refresh and new design. Too bad cannot find the dual screen for it.

I dont recommend to buy from Shopee which mostly are refurbished set. Last time bought G8 for my friend and after 1 year sim card cannot use data. While i read others feedback, few months use cannot turn on suddenly.

My supplier sell used set but I'm not sure whether it's really used set or refurbished set.
It's direct from Korea though.
