Upgrading a Lumia 640 LTE to Windows 10 Mobile

MTN South Africa is shipping the Microsoft Lumia 640 LTE with Windows Phone 8.1 Update 2 which is an okay Phone Operating System however the Lumia 640 is one of the phones that can be upgraded to Windows 10 Mobile now. If you don’t havea Lumia 640, the list of Lumia Phones that are eligible for the upgrade available here at the bottom of this page.

According to Microsoft, you should be able to update the phone by going to Settings > Update & security > Phone update and tapping Check for updates. However this did not work for me.

I found that by installing the Windows 10 Upgrade Adviser from the Windows Mobile Store, I could force the upgrade. After running the Adviser App, go back to Settings > Update & security > Phone update and tapping Check for updates. The phone then showed that the upgrade is available.

The update is about 600MB and takes about an hour to install on the phone. After the upgrade completes, the phones app’s also need to download updates. This is another 35+ app updates. While the app’s are downloading, the phone is slow.
