What are your current concerns with the S8 that you didn't mention here.
What are concerns about the LG G6? I am considering buying one.
The S8 memory management is subpar for me. It makes any gains the 835 (or 2017 exynos in my case) offers over the 821 and pees all over it because whilst I can only cycle between 5-6 apps on my S8 before forced content refreshes and reloads, I can go 14 apps on the G6 which makes the G6 feel so much faster in day to day usage for me.
I am still getting the odd false touch but no where near as bad as the S7e.
Not being able to find a screen protector I actually like or feel. I hate not having a protector and it makes me anxious when taking device a out into the wild.
The redundancy of the Bixby service and button irk me, especially when inadvertently press the Bixby button (sometimes when rotating my device to horizontal mode) and I'm interupted & reminded of a service not offered in my region / working.
Battery life on my S8 has been inconsistent.

The G6, lack of regular monthly security updates and still on 7.0
Not sure of LG's commitment to keep the device up to date and fear it may dwell in software limbo if they prioritize the V30.
Over sharpening post processing on the camera irks me at times too, but it is the
Software update frequency and longevity is my primary issue with LG.
Honestly .... I will be getting rid of both and jumping on the Pixel 2 XL as the G6 style design (no curved screen) with proper software updates and assurance of them would be my preference. Though if Google yet again doesn't offer the pixel in my country and I have to import, I'll be holding onto the G6 longer and will be selling the S8 regardless.
