Oil ran into my phone and the micro is not working anymore

I’m assuming you have a Fairphone 3 (or Fairphone 3+).

Smartphones often suffer from water damage, there is a basic guide how to handle that here:

How to handle water damage

Since this happens again and again and there is a lot of useful info on the forum, but people usually read it too late I’ll gather it here in hope that you read it before this happens to you. This is a #wiki so feel free to add info by editing the post. First things first: Turn off and take apart If your phone comes in contact with water and there is even the slightest chance that some droplets or moisture entered it then turn off the phone immediately. The fastest, and only in…

Now in your case, oil might be a bit different. Anyway, you should disassemble your Fairphone as far as possible. Perhaps the oil allows you to better spot which parts are affected. Some tips as to what you can use (usually very pure alcohol) to clean are given in the above guide.

Water damage usually voids the phone’s warranty. But I still want to add that if you follow iFixit’s teardown, only steps 1 to 7 are within Fairphone’s warranty while opening the modules in themselves is beyond.
