The update deleted my shared contacts  it works well  but can take a while to connect an audio call  video seems to connect more quickly  also not able to delete sent texts. Gboard works great allows voice to text. Still needs work  and 'lists' email address not working. Keep it up  only 1 of 2 P2P comm suites I've found (the other is unreleased alpha). Love 'no trust' concept. Runs in background ALL the time  no issues with data consumption  as others stated. Running Ulefone Power Andy 5.1 (still) not updated to 64 bit yet.
