Fairphone 6 – Warranty denied due to “generalized oxidation”. Is this justified?

[Hmojito]

Hi everyone,

My Fairphone 6 touchscreen stopped working. After testing a replacement screen and ruling out software issues, I sent it in for repair.

The result: warranty denied due to “generalized oxidation” and a €262.06 repair quote to replace the motherboard.

The phone has never been exposed to water or other liquids.

I requested photographic evidence, but the pictures provided are not clear enough to identify any actual corrosion.

Fairphone’s repair partner explained that “generalized oxidation” is an internal diagnostic category used when traces are found on several components, even if the entire device is not affected.

Does anyone see clear evidence of corrosion in these photos? And would such corrosion justify replacing the motherboard for a touchscreen failure?

I’d appreciate your technical opinions and any similar experiences with Fairphone’s repair service.
