iPhone 4, Touch Screen doesn't work, charges slow?

[HipsterHD]

So I just bought an iPhone 4 off of a friend. He gave it a colorswap with a mirror so it looks awesome but he said somewhere down the line he had to replace the LCD connector to it. Here is a full run down of what happens.
Press the Home Button; screen turns on, unable to slide
Volume Down Button - Nothing
Volume Up Button - Nothing
Ringer Switch - Works
Power Button - screen turns on, unable to slide
And when I plug it into my computer the battery doesn't get a lightning bolt on it, but the power slowly increases.​

Seems to me that your friend didn't do that great of a job doing the swap. My suggestion... return the iPhone back to OEM specs using parts and the How-To from here... iPhone 4 AT&T Repair Manual - iFixit or iPhone 4 Verizon Repair Manual - iFixit.
