New phone screen. Why are my colors off?

So I dropped my phone and, because I have horrible luck, both the panel and the screen broke. So I took it to my local phone repair shop and they fixed it. Now looking at it closely I can see the colors look different. At first I thought it was just that it was new and my eyes were used to an old panel, but then I compared it to my computer monitor which has great color reproduction that I use for video editing. I know it's accurate. The color reproduction on the phone is definitely off.

That's not the only thing though. If there is a solid black on the screen and I swipe, it leaves this kind of trail. That's the only way I can describe it. It's annoying when a lot of icons have black in them, trust me.

Anyone know what part of the screen is the problem? If I know what part is the problem I can probably fix it myself.
