Where do I clean if I got finger oil on my parts?
I had my iPhone into a shop for repairing when my power button failed. After I got it back, I have very bad bluetooth reception and almost non-existent WiFi. I remember that the shop did not use gloves. I took it back there and they are denying all responsibility.
So I assume that there's probably some finger oil on various parts and I've seen all of the suggestions on here about cleaning "all contacts" with a degreaser or Windex. But I don't know what "all contacts" are. Can someone help me out and point them out?
This is a pretty common problem, and you're correct about the finger oil causing bluetooth to fail.
There are a couple places that you should clean the contacts before re-assembly. While many of connectors in the iPhone use plug-and-socket connections, many just use spring pressure contacts. These pressure contacts are those which you should clean off. Here are a few:
- Dock Connector Contacts
- Near the vibration motor (double check this one, it is likely the culprit)
- Grounding Pin
Use some isopropyl alcohol or some Windex on a Q-tip or microfiber cloth, and you should be golden.
Good luck, and let us know how it turns out.
