@linmob it's definitely not a failure - it's intended as a development device, and even then I've been using mine as my only phone for almost 2 years now.
I do find it frustrating that the Pine64 business model relies on all the software being developed for free by the community, and although the community has done a great job, I don't think that great stability or a solid user experience are going to be possible from people working just in their spare time.
