@ernest Thanks for your answer. It does not look very serious from the list, but also i do not understand issue #63. What does actually "Calls and network mobile information does not work" mean? I also found that issue #71 is marked as a duplicate, so is it the case that it is fine except that you can't hear when it rings and you'll not be able to connect to mobile network?
Will i get all release candidate updates for this device by installing the 15.04/rc channel?
