The ear piece volume was greatly reduced. Had to use speaker phone for calls
Almost perfect. I put it all back together and the center of the display would not respond to touch. Took it apart again and found the piece of black tape in step 22 got into the socket of the digitizer plug (it must have gotten stuck to the tweezer when I restuck it down. Put it back together and it's fine. Ear piece volume perfect. Thanks
Take a few pictures as you go so you can zoom in to see more detail. Also use some sort of a magnifier to enlarge the work being done, I bought an inexpensive hood type that fits on my head. There are a few YouTube videos out there that complement the ifixit instructions. I hate when I'm forced to upgrade (I'm using the original OS too) THANKS ifixit!!!!
