Wow this is a sad story. Since you recently got it from us, I suggest giving the warranty exchange another shot. This isn't a known issue with this phone so it's surprising this has happened. You can reach out to LG to see if they have any thoughts on this, but you should allow us to replace it for you through the warranty.
I appreciate the e-mail back. I just couldn't do it. I went through four
phones and just couldn't handle a fifth. I ended up paying off half my
phone's balance in order to "jump" to an HTC 10 that is flawless and works
as it should. I am definitely not happy I had to shell out so much money
just to get a phone that isn't defective. Also, if you google "LG G5 back
light bleed" or "LG G5 screen issues" you'll realize that this is a well
documented problem. Also, the representative from whom I bought the HTC 10
said a lot of T-Mobile customers were complaining about it, too. I did
think about reaching out to LG, but their turnaround time is two weeks. You
guys don't offer loaner phones anymore and I can't be without a phone for
two weeks. These are LG phones made by LG. The defects are on them. What
does make me angry, however, is that apparently T-Mobile doesn't inspect
the refurbished phones they send out. I specifically asked the
representatives, "Please note my account so that the screen is specifically
checked for before issuing me a replacement." Either they did not check or
simply didn't care.
Thanks for hearing me out.
