I have the same problem. During the last week, all Meizu pro 6 phones that I know (my, my wife's phone, my friend's phone) reload every hour, sometimes more often. At all the system costs Flyme 6. Today I rolled back the system on Flyme 5 - the camera is frozen, the phone does not restart.

same here. weird, and extremely annoying ,frustrating. Meizu!!! come on!!!!!!!!!! Our phones have become useless 3/4 of the day like this. Does anyone from meizu (flyme) reads these?????

I had for a while the same problem and I found eventually the faulty app: Facebook. So I uninstalled Facebook and now my Meizu works very well without restarting every time. It  might be a software compatibility problem. Is it possible for you to have the same problem? I have a Pro 6, try and let me know;)
