So, my 7 plus was yellower towards the bottom. Not horrible, but enough to annoy me. I used the phone for a 2 hour skype call today and then nothing till this evening. Looking at the screen it struck me that the yellow seemed mostly gone. I opened up the test images and was having a hard time even noticing the uniformity issue.
In disbelief I did some internet searches online. There are quiet a few people around posting on different forums around the internet with various different phones and tablets who are saying that their screens got better with time. Multiple people are saying they let their phone play videos all night on full brightness and the uniformity issues improved a lot.
That seems somewhat consistent with what happened after my long skype call. Anyway, I don't quiet belief my eyes tonight. But last night the screen was annoying me with obvious yellowness at the bottom. Tonight I'm having to look really hard to see the problem. In fact, I'd now say my screen is good enough.
I'm going to play a youtube aquarium video all night at full brightness. We'll see.
I noticed a few people on this forum saying their yellowness issues improved with time. A lot of people say that. So, I suspect there is something to it. Whether it's glue is not known.
I think that those with this issue, as there is a 2 week return time, should wait a week. Try playing videos over night on the screen. See what happens. I'd be curious for others to report back on the outcome of these experiments. I'll report back in the morning myself.
Be careful with that lmao, you're going to get the pessimist going again. I noticed this on mine too and I've been checking it daily. My screen is brighter and better than day 1 after a week use. I could careless what the naysayers say it's what I observed.
