I had the same problem with my Z1 I think it is due to memory leak in Andoid 5.0 and 5.0.2 Samsung and HTC owners have the same problem. I have solved the problem by moving all my apps (which can be moved) to the SD memory card. I live in Norway and everyone here has or had this problem, but for my part it is now resolved.

Have you tried disabling noise reduction under Settings > Call? If not, you can give it a try to see if it helps.

Does this happen when in safe mode as well? To turn the safe mode on, press and hold down the on/off key until the menu pops up. Here you press and hold down on the 'turn off' option until you get a question asking you about safe mode. Try running the phone in safe mode and see if the problems persist. If they do not, the issues you're experiencing is caused by 3rd party/installed software.
