I have a Xioami Note 3 Pro I got from PB Tech a few weeks ago (I see it's on special today saving about $70 from what I paid ouch lol). It seems pretty good, I seem to have something draining the battery as it only just lasts a day of moderate use, I'm pretty sure I should be getting more, but the major issue I'm having is that I'm missing calls. People will try and call me and it will ring for them a few times and then they'll get a busy signal, it doesn't even seem to go to voicemail for some reason. Some calls do go through but of course I'm missing calls I don't even know I'm missing. Sometimes I can try and make a call and it won't work but it usually does. I think it has something to do with the phone going to sleep or being connected to wifi. I've found numerous threads online including in the MIUI forums about this issue so it seems I'm far from alone on this one, but I can't find any solutions that seem like is universally accepted and their doesn't appear to be any official response from Xiaomi from what I could gather. Had any NZ uses had this issue? I'm on Skinny. Maybe @NikT might have a solution? It's pretty useless at this point as a phone if I can't receive calls randomly.
