Hello Javi,
I would wait for the FP3. I bought a FP2 in July 2016 and I’m rather disappointed about this phone. I’m experiencing many unexpected reboots and looking at the forums looks like others has the same issue and there is no clear solution.
The case is not also nor resistant at all. Mine is broken (around the headset jack) and I have a friend who had the same problem. I just bought a new one and it’s cost me 40 euros for few inches of plastic. That’s not very fair…
