Last weekend the telephone froze (after turning off hotspot). And I had
to hard-reset it using the power button.

Then the strange behaviour began:

On startup, only one sim card (without pin) was working.

Also I was unable to unlock the pin protected card (there was no dialog asking 
for the password).
Even wehen trying "Unlock" from the configuration didn't do any action.

The icons to start applications didn't work, but it was possible to scroll 
through them, only starting an application was not possible.
But from the slider on the left side it was possible to start an application.

Rebooting didn't solve the issue.

A workaround for the pin-locked SIM card was to disable the PIN and then
enable it again. That unlocked the SIM card, so that I am able to use it

Using df via ssh didn't show a full disk, maybe the file system was
corrupted during hard reboot.

This seems to be the case as not only the network indicator was broken
but also the application which asks for the SIM PIN and the launcher.

Probably we should have a look on how configuration files are written by
applications and how corrupted configuration data is handled. Broken
configurations should not leave the applications in an unusable state, I
would prefer that instead a user notification is sent and the
configuration is reset to the last known working state or to useful

Bug description:
  Sometime in the last few days my phone lost the ability to connect to
  wifi networks and the network indicator at the top has stopped

  Currently between "Bluetooth" and "Sound" I have a gear icon and the
  caption "indicator-network".  When I select it, the rest of the screen
  is blank.  There are no settings available and no way to connect to a
  wifi network.

  On the System Settings app, if I tap on the "Wi-Fi" icon, I can see
  "Previous networks".  But below that the page is just white, there is
  no way to select a wifi network.

  Rebooting the phone doesn't seem to fix the problem.

  Given that this is an MX4 and therefore the USB port doesn't work, and
  there's no SD card slot, there's vanishingly few ways to get data in
  and out of this phone now.  If there's a solution to the problem, it's
  going to have to involve something other than updating system

  Current system software is Ubuntu 15.05 (OTA-12).


  Per the comments the .config/connectivity-service/config.ini file
  seems to hold bad or outdated info and needs to be manually deleted
  and then recreated by the service.
