Headphone connector can't hold on to Headphone Jack properly

Problem core:
It takes literally next to no force to unplug the earphone jack. When held by the cable, the weight of the phone itself is enough to uplug itself.

Just tested this with my (also non-400$) earbuds: when I plug them in and hold them by the cable, the plug easily carries the phone. So I strongly guess your FP2’s top module is the problem.
