I Cracked my iphone 4, screen flickers not sure why?

I cracked my iphone about a month ago and i changed my housing about 2 weeks ago.unfortunately, i cracked it again. But this time, my screen flickers and changes colors.sometimes it fades to black, i'm not sure if its because its cracked or because it has water damage.

Thats happened to me before. I dropped my phone in the pool and it started doing that. Ihad to dry it out.

Hmm, this sounds really unusual. Did you ever drop it in water or did it happen after you cracked it? I would change the screens around, which is what I did when my screen started going crazy! I followed the iScreensFix.com repair methods, I'll leave the link for them below they are actually amazing! They got my phone up and running <3333
