Same bug with contacts on Meizu pro 6s too. I used to type the first 2 letters of the contact to find the contact but now the search doesn’t work. It’s being posted in Meizu m2 thread too. Also this bug is draining the battery somehow. I use gsam battery monitor app and it’s always has the contacts related process on top. Tested this with dirty flash and after a full factory reset too. The problem persists. Also I have a problem with music app. S ome songs even if they starts from the beginning the timer underneath shows that it starts from tenth second , some at fifth second etc.
