Our readers in Quebec may want to temper their excitement for any upcoming Lollipop updates. According to this lengthy thread on Google's Android issue tracker, a number of French-speaking users are seeing system-breaking bugs. When setting an Android 5.0 device's language to Canadian French, it will periodically experience a SystemUI crash, usually when plugged in to charge or sync. The problem only seems to be affecting those who select "Français (Canada)," not "Français (France)."
So far users on the Nexus 5, Nexus 7 2013, and Nexus 9 are experiencing this problem, all running release builds of Lollipop.
