well i use nexus 6 and i disabled the android using netthunter but i upgrade to kali linux meaning the chroot is nethunter but every think else kali linux
nmap -p- -sU -sV -T4 takes around 2 minuters to 3 minuters for me to complete
to be honsty it better then laptop for me. that being said right i just was able to get user on fighter using nexus 6 only!! and about to get root!! i dont about oneplus tho. all i know is that i reconfigred every thing to my liking nexus it not even phone. it more like mini PC 
i can do every thing except burp + owszip etc.
meta exploit fully installed too but i try and stay away from metaexploits and use more python base exploits… any thing i can’t do on nexus i just do it at home.
