[Bug 1588349] Re: Checking for updates never finishes on 3G when no updates available

[Anupam]

** Description changed:

  If I'm using wi-fi and go to settings and then select updates, "Checking for updates..." screen appears with a spinner for a few seconds; if there is any update available it shows, otherwise informs about the unavailability of updates.
  But while using mobile data (3G/H) *if there is no update available*, it gets stuck on the "Checking for updates..." screen and the spinner keeps spinning. I waited as long as 10-15 minutes.
  Note: If there is an update available then the behaviour is normal, i.e. shows the available update(s) after a few seconds.
  I'm seeing this behaviour from the very beginning (OTA-6 days).
  
  Related to bug #1528886

+ UPDATE: It's gotten weirder after the introduction of the new update
+ panel in OTA-13. When there is an update available, it keeps on
+ "Checking for updates..." along with the list of available updates:
