Why did Fairphone use an outdated SoC for the FP4 even though they knew Qualcomm would not support it longer?

Hello everyone, (I’m reposting on this topic because it seems that my topic is similar)

I would like to buy the fairphone 4, but I wonder if the processor is powerful enough in the long run?
Won’t the phone get really slow over time? Even for basic use?
I can’t imagine the fairphone 4 supporting an android 14 or 15 properly.

Personally, I would have preferred to pay a little more for the phone and have a more viable processor in the long term.

What do you think about the processor ?

Thanks in advance !
