Later this month the v20 is supposed to be out. I just don't know though. Samsung still has the best screens. Would the Edge be a downgrade over v20?
Screen wise just the opposite LG screens aren't the prettiest to look at , cameras are going to be close, sound wise definitely a downgrade, ir blaster on the v20, shouldn't be a issue with a glass screen protector on the v20, you do have 7.0 on the v20.. and it will have a removable battery..
These are 2 very different phones..
Now the bad.. The v20 will have lg's UI and depending on which carrier you have may or may not have a factory recovery. No one knows if they have fixed the bootloop issues they have been plagued with and they aren't the greatest when it comes to optimizing the os. No way of using package disabler pro on the LG and no waterproofing.
The really bad about the US version of the edge is it's abysmal sounding speakers and crappy battery life. If you can get a unlocked Eynox version and the really bad won't be present. If you use a great BT headphones with AptX it's not as bad but it is doable if you aren't a audiophile.
Personally.. I would get a full refund then find a really inexpensive phone you can buy outright to use till all of this settles down.. I went with the Nexus 6p and actually love it.. I won't be buying anymore carrier branded phones again, as good as the Notes are I just don't need the bs associated with them or the carriers and this phone is a kickass phone on 7.0 sans the s-pen.. And both new Pixels will be out next month sometime as the rumor mill states..
