I am happy for all members & user who testing alien dalvik in one plus one device but it need many tweaks and find solution to fix bugs or glitch I try to install this from "alien dalvik nexus 4 " that post before I find that when I install something the screen closed or minimize that let me to restart device to be clear it is complex , I hope there some fix , I prefer to use Firefox and whatapp but that not happen for me when I using alien dalvik before maybe if I have time I try .
also bugs and glitch make me stop to using it.I love" sfdroid" that let me using many android app but the project is end for many reason and " anbox" is in early stage as alternative and it is coming to Ubuntu toutch also as I know some member of sfdroid team now working together with anbox team to bring anbox to sfos ,
.I hope opo device work will with alien dalvik without any problem

finally I have image backup with google play ready to use I try the new config for platform and see what happen than ...

Many thanks

Good lucks ....
