Hello!
My FP4 took a bath into the sea…
I opened it, washed it and dried it (for a week). The battery was defective (low voltage and oxidation) so I bought a new battery. Now there is a vibration when I turn the phone on, but the screen stays black.
I would like to know if there is a procedure to know if the motherboard is working and if I can order a new screen, or if I have to buy a whole new phone…
Hey,
I don’t think there’s any procedure to know if the motherboard is still working, but that said, since it does vibrate, it means that your motherboard isn’t completely dead. Maybe it’s just the screen or the connector.
What I would recommend is that you contact your local Fairphone angel to see if they have spare parts to test and if they could help clean the inside, since the salt (or other stuff) will stay there even after it’s dry.
I dismantle the phone entire in the next hour, but I clean it with clean water only 10 hours after.
I clean it with isopropyl alcohol several days after, and waited again a couple of days before turning it on with a new battery.
I don’t think the computer recognises the phone when connected via USB, but I will try again later this weekend.
