That sounds like an excuse and for the bottom module: its’ not 1000 components like @Leo_TheCrafter demonstrated in New Fairphone 2 Bottom Module with an appropriate case
The bottom module is one of the most failing parts, nearly all my cases in Berlin Fairphone Angel heaven circles around failing bottom modules. If it can’t be repaired or replaced, the phone becomes useless.
So Fairphone says, the 2 year old FP2s bottom module can’t be repaired.
Fairphone can’t replace it.
No 3rd party repair shop can repair it.
The Blueprints are closed source, so nobody can ever repair it.
So a failing bottom module (and the risk is high) means end of life.
