Repairing my Galaxy S4 - Don't buy cheap Chinese knock-off parts.

This is just a tip for people wanting to repair their cell phone, although this is pretty specific. The charging port went out on my phone, and I found really cheap board replacements on eBay. For a few bucks, I had it in a week, installed, and my cell phone charged fine again. However, reception went to ****. Fast forward another week, and I ordered a used board for $7 and my phone is finally back to normal with good reception. Keep this in mind when ordering parts!
