My experience with it so far On the usability side - Push notification works well so far - If the app is in the background, it will always show "Searching for data connection" , however, it connects once a message is received - Battery consumption is an issue if the app is kept running in background (could be related to the constant "searching for data connection") - A bit slow to start up and lags occasionally needed features - Group chat - Data sharing (image, sound, location...etc) - Message indicator for LPM
