I'm pleased yours disappeared. Mine which is identical in both the place and shape has been on my G3 since I got it back in July.
It still gets darker the longer you have heat build up on the screen and when it's cooled down its faint again.
Sorry guys, I forgot to come back here with an update.
Mine eventually disappeared last week after nearly 3 months.
I believe it is the glue.
Someone told me to try leaving the phone under UV lighting. I left mine in direct sunlight for when it was not being used. Seemed to cure it in a few days.
I've updated my phone to lollipop v20e a couple of days ago. Today I noticed this little yellow spot in my phone. Coincidence or not I began to use NFC TAGS early this morning, can this be related using the NFC TAGS and having this function enabled?
I bought my LG G3 on the 20/07/14 and after 5 months of use I have a long yellow thick line across the top left of the screen. What makes this even more concerning is my cousin bought the same handset a week before me and his now also has a thick yellow line on the screen. There is nothing you can do to get rid of it and it is more pronounced against a white background.Looks more like screen burn. Both my cousin and I have contacted LG and we are having to send our handsets to them for repair.
I have never experienced this issue with any other handset i have owned. I was unhappy that i had the issue but even more pi$$ed off that my cousin has the same thing happening which tells me either it was a huge coincidence or that these things are not fit for purpose and more and more will be going wrong in the near future.
My handset has been well cared for and never dropped. I am a moderate user so this was even more of a surprise. While the LG is getting repaired I am using my Sony z2 work phone as my personal for now and I don't think I will be swapping back when I get my LG back.
Good luck to anyone who has this issue. My concern is the same thing will happen again and then it will be my problem as it will be outside of warranty.
