My phone got water-damaged so I took it to the local phone repairer and they said there’s water trapped between the two boards and apparently is it not repairable. Is this true or not? Should I sell my phone(Even though I’ll probably get like £50 for it). Thanks!

It may be repairable but most micro-soldering shops/techs will not “fix” a water damaged phone just for the sake of the phone as they are typically unstable long-term and warranty issues can quickly become a nightmare for both the owner and the shop. Most shops will only work on water damaged phones for data recovery purposes. That said, if you call around you may find someone willing to take a deeper look inside.

Apple will replace the device for you, but that is not cheap. If you went to 3rd party places, say goodbye to Apple. Water between the board layers is repairable, but not sure anywhere outside of China has that kind of skilled technicians for cheap.
