Hi @jessiedeguzman
Seems like there's may be a problem with the screen.
You did mention that the phone was cracked, so did you mean the screen?
Heat expands, cold contracts so it may be that there's a faulty internal connection in the screen itself that when the phone is cold there's good electrical contact but when it warms up the connection is broken causing the problem to reappear.
It could also be a faulty screen flex cable connection on the systemboard as well.
You may have to temporarily replace the screen and check if the replacement works OK or not. If it does then the original screen will have to be replaced as it cannot be repaired.
Here's the ifixit [guide|154720] guide that may help.
