Recently, Microsoft announced that the Windows 10 free upgrade program will end on July 29. After the deadline, Windows users have to pay $119 to get the software on their laptops/desktops. Speaking of mobile devices, Microsoft has started rolling out the Windows 10 Mobile Cumulative Update for May.

Upon downloading and installing the update, devices should show the following software version: 10.0.10586.318. The tech giant suggests Windows 10 Mobile users to check for the firmware update by navigating to Settings -> Update & security -> Phone update -> Check for updates.

The change log published by Microsoft shows the following fixes and improvements:

  • The Windows 10 Mobile Cumulative Update brings in improvements specific to device reliability, performance and stability.
  • A fix for the unprecedented “battery drain problem,” experienced when the Windows 10 handset’s display is off, has been added.
  • The “update system” has also gone through some changes to prevent Windows handsets from getting the following errors 0x800f081f and 0x80070570, when trying to get the firmware update.
  • A fix has been added to stop the Windows handset from showing incomplete set of app tiles on the Start screen, after going through the initial setup wizard.
  • Changes have also been made to improve the reliability of USB Type C connections.
  • Digital personal assistant Cortana has been improved in this cumulative update. The problems pertaining to music playback and issues surrounding Quiet Hours have been fixed.
  • Upon visiting certain websites using Microsoft Edge, some Windows phones either hang or restart. This issue has been fixed in this update.
  • The reliability of internet connection sharing (ICS) and tethering has been enhanced.
  • In some Windows 10 handsets, recorded videos went missing while attending incoming calls. This cumulative update fixes this problem.
  • The navigation bar overlay problem has been fixed.

Windows 10 Mobile users that purchased the device from carriers may have to wait a bit longer for the update to show up, GSM Arena noted.
