Yellow spots after digitizer swap

Hey!

After changing the digitizer on my Nexus 5 for the second time, i have yellow spots on the corners. I guess it's the glue. The first time it didn't happen.

What's the best way to get rid of yellow spots? Will i just have to wait a couple of days in the hope the glue is completely dry? Or will i have to keep a white background on maximum brightness for a long period of time, or show some UV light/sunlight directly to the screen for a couple of hours? Or will i have to open the screen again, but what would i need to be looking and doing then exactly?

When you put the phone in the freezer for 15 minutes the spots are almost gone, but they reappear after the display gets warmer. I don't think dryer would have any benefit here, or will it?

If you use white background, the spots are visible like burning-like, when you use pitch black background you see this "black eating" effect on the corners strongly that wasn't as noticeable before the screen swap. The display itself is OEM original, and the first swap was successful, didn't result in any yellow spots.

I read that it was a common thing for iPhone 4s back in the days as the glue wasn't dry enough from the assembly line, but after a couple of days the spots went away.

it looks like this:
