To start I am currently using this part but the quality v the quality of the original are black and white, the frame of the original is made from milled aluminum, the aftermarket is milled from plastic, I will say it was milled well, the parts fit where they needed to BUT for what this thing cost it shouldent be plastic.My pictures I have posted are in pairs to show the original v aftermarketThe first set is the heat sink, on the old one the heat sink is nice shinny copper and the new after market one it looks like it was refurbished , it's bent up and looks used, and covered in oxidation real poor quality on the after market part.The second set of pictures is of contact points between the frame and boards, there are part of the frame the board should be touching on aftermarket the simply milled inserts for small metal pieces, they also dont line up the best. Poor quality from the after market parts.The cover for the speaker was milled well on the bottom of the phone so the cover won't sit flush but at an angle. This causes problems for fitting it together flush and smooth. Poor quality on the after market parts.The volume button is also falling apart and comming out of the frame another very poor quality part on the aftermarket part.I paid $179/$180 for this part and it's fisher price quality putt in a cell phone. Poor quality parts and construction. With how bad all this stuff is I'm amazed it's actually work although I assume being out on a hot day it's going to over heat way faster than it normally would, I'm constantly concerned about losing the volume button so needed to buy a case to keep it enclosed.Bought this last because with the back glass the outside of the phone is basically new very easily.I found it probably would have been cheaper and better to buy the parts separately.
