Today we've released handivi 0.4.17 version, which address the following problems, kindly reported so far: a) it doesn't run on my ZYX phone, b) is slow, c) the public timeline/friend updates isn't correctly refreshed, d) crashes, and finally e) it has bugs.

You've might notice some pattern there, and you're right, this new version is only bug squashing.

As you can see, some could not yet be squashed and more just "cut the line", but we're working on it, bear with us and report your problem, or just say hello@handivi.com
