What about measuring the power drawn by the device? And while at it also careful check the datasheets of the components if the tolerances of the hardware components are meet. I cannot comment on netifd since I don't know anything about it. But it could be that ConnMan and oFono together do more CPU work hence the device drains more power. I can tell you from experience if the CPU doesn't get enough power you see really random crashes and weird behaviors. Check the reports on Raspberry Pi and power supplies. Thanks, Daniel
