Did you use TPU for the prints? If you used PLA, that really was a bad idea. With TPU my drop tests (not on purpose) were successful and the phone without damage everytime (so far)
I get your problem, yes. I also tried printing a bumper for my work phone in PLA a couple times before I was able to print TPU and it always took like 2 weeks until it broke. Those materials don’t like being put under pressure permanently. I didn’t try PETG, could imagine it to be a little better, even though it won’t absorb any impact if dropped.

I used nylon carbon fiber.
That sounds durable, but not flexible. Am I right?
It’s durable, and is not inflexible but is quite brittle. I have also tried in pla and got similar results. It just never ended well.
