I (Moto X 2014) got a different set of bugs on M. Mostly problems with basic functionality: - When I get called, half of the time I don't see the name of the person when they are in my address book. - Music controls (which were already very basic) usually stopped working a certain amount of time after the last restart. - Music randomly pauses when browsing the web at the same time (as in, I have to open up the music notification card and press 'Play' again). - E-Mail notifications have been flaky for some reason. - Active display music controls are worthless again. Google decided to add a 'favorite' button. Motorola just picks the first three buttons from the notification card. Now you can't go to the next track anymore. Security updates were also still at the 1 November 2015 level. After being stuck for half a year on a buggy 5.0 release before getting 5.1, I know this is going to take months to fix, if ever (Lenovo probably doesn't care about the 2014 anymore). I am now back to an iPhone after a Nexus 4, Moto X 2013, and Moto X 2014.
