The earpiece speaker was no longer working on this phone. I replaced the battery just because it was an old phone and more than likely it needed it.
The repair went well. I missed on screw on the main board and bent it a bit when i was trying to get it out. This iPhone 4 was quite a bit different than the guide. The screw that i missed was at the top but was covered by a sticker. All is well though I did not damage the phone in the process and everything works. Just need to give it to someone else to enjoy for a few more years.
I took the phone apart before i ordered the parts on this one. I read that this was one of the harder repairs and I seen why. Made sure I did not break anything during the tear down before i ordered.
