Imho, they are same processor generation, and still plagued by image retention issues on the LCD.
Well yeah, you got nice sounds if that is your only purpose for that phone.
Better get the next generation, or other brands like axon 7, not necessarily LG series but one with dedicated DAC.
And your phone LG g6? I had the v20 once and most of us in the group had the image retention issues.
I mean get the axon7 that is same generation with LG g6/v20. Budget wise. Sorry for confusing statements
