are there any water seals associated with the pentalobe screws? I blew compressed air into my iphone 7 and two tiny square rubber gaskets (~3mm) popped out. They squares have a round hole in them. I can only figure they are part of the pentalobe screw water seals, but I’m not sure, and I don’t know how to put them back in the phone to restore the water seal. Can anyone offer a solution?

@ataterka The screws themselves have a tiny ring-shaped rubber gasket on them. The two rubber squares you found slip onto the screw bosses. I don’t think those are needed for water sealing, and they’re not even included on newer models.
