Windows 10 Mobile has finally arrived for many Windows Phone 8.1 devices, but quite a few smartphones have been left out. Even though not making Windows 10 Mobile available for 512MB handsets might be understandable, both Lumia 1020 and Lumia 1320 meet the hardware requirements for the update.



Unfortunately, Lumia 1020, Lumia 1320 and Lumia Icon have not received Windows 10 Mobile, and the chances are slim it will ever happen, according to Microsoft.
Currently, the list of the smartphones compatible with Windows 10 Mobile update contains 18 devices, but only a few are older than 2 years.
Microsoft has also confirmed that it will not release Windows 10 Mobile for a second wave of the devices, but it’s still considering the Lumia Icon for the update.
But that’s not the case for Lumia 1020 and Lumia 1320, as neither will receive the upgrade from Microsoft. In case you’re wondering what made Microsoft skip these rather powerful smartphones and not provide the long-awaited Windows 10 Mobile for either of them, here is a possible explanation.
Bad performance, low recommendations According to Microsoft’s Gabe Aul, the reason the Redmond-based company decided not to offer Windows 10 Mobile updates for Lumia 1020 and Lumia 1320 is the higher percentage of performance issues, as well as the lower percentage of votes of users likely to recommend the upgrade.
The percentage mentioned by Microsoft’s official is based on the user feedback the company received during preview builds testing.
Basically, Microsoft took advantage of the Windows Insider program and based its decision on the feedback it received from users. So the reason Lumia 1020 and Lumia 1320 owners won’t have Windows 10 Mobile on their devices is the fact that those who tested preview builds decided so.
Both Lumia 1020 and Lumia 1320 have been cut from the list of compatible devices due to bad performance and low recommendations with the Windows Insider program.
Naturally, that doesn’t mean that those who still own these old smartphones shouldn’t be upset. The bottom line is nothing can be done but switch to a newer device.
