Since my Zenfone2 is collecting dust in my drawer and I don't really plan to use it anymore:
I am willing to send it for free to any developer that is seriously interested in porting UT to it.
It is the 64GB, 4GB RAM version currently with LinageOS 15 or 16 (last official release, not sure) installed. Battery isn't the best anymore and the camera glass is a bit scratched.
To keep postage costs low I would prefer someone that lives in the EU.
