Chosen Solution

I have a fairly new iPhone 6S. About 1 month after buying the phone the power button stopped working. I already followed the iFixit guide to the point where I could unscrew the power button and check everything. I have not yet replaced the flex cable though, since the volume buttons and flash work perfectly. A second problem arises when calling: a lot of crackling noises to be heard through the earspeaker. When recording through voice memos the playback is fine through the earspeaker. Anyone got an idea? Is it possible the power button broke by itself only after 1 month of using, whilst volume and flash continue to work? Would the earspeaker problem be caused by the antennas or something? There’s no warranty anymore on the device.

I mean, the phones been out for a year and a half now. Yes, those things could be not working, while the other things could be working, on the same ribbon cable. Even though the cost of parts is very cheap, these are extensive repairs, and plenty of room for things to go wrong. Anyways, here’s some parts and guides.
