What a nightmare using this upgraded version 2.8.8. Does not connect over wifi or data. Stay at connecting till you or phone dies. Some times if connected by mistake, you or other party can not hear you. Such a poor development team and QA team these guyz have. They even can not provide you the previous version on requesting. They say, "Sorry it is not available". They do not have storage to back up their own code it seems. I am returning the device. Lets see if they refund or they say "Sorry it is not available".
