Title:
  Drops carrier on screen lock on Ubuntu Touch: Meizu MX4 Ubuntu Edition

Status in ofono package in Ubuntu:
  New

Bug description:
  I am using Meizu MX4 Ubuntu Edition Phone. OS 15.04 (r4)

  The carrier is lost when the screen gets locked after preset timing or
  after there is no activity on the phone. I have to restart the phone
  everytime to get a GSM carrier signal.

  It is for every connection type 2G/3G/4G.

  The carrier selection option is set to automatic and I cannot set it
  to manually either.

  Anyone else calling on the number gets intimation that the phone is
  switched off.

  The idea of having a Ubuntu phone is getting defeated here since the
  phone keeps dropping GSM carrier/signal on its own.

  Any help from the community is highly appreciated

  Operator is Reliance, Country India

  Regards
