Microsoft explained: Some old WP devices can not be upgraded for user experience

Computer store news: We still remember that Microsoft said that all Windows Phone 8.1 devices can get Windows 10 Mobile updates, but this is not the case, but Microsoft has Full reason. When Microsoft announced the Windows 10 Mobile update push, Microsoft's Michael Fortin also posted a bad news:

This list includes some Windows Phone 8.1 devices, excluding the current participation in the Windows 10 Mobile Insider program. Some devices running Windows 10 Mobile. Windows 10 delivers important new innovations, but for many older devices, it's impossible to get a successful upgrade without compromising the customer experience. Our goal is to provide Windows 10 upgrades for devices that continue to have a good customer experience.

In other words, some Windows Phone 8.1 devices from Nokia and Microsoft can run Windows 10 Mobile, but the experience is not good. The Lumia 530 can't even download updates if it's not cracked. The lumia 920 with 512 MB RAM (original 920, should be wrong, 512M Lumia model existing Lumia 630/530/720/625/620/520) and 630 Even running basic tasks cannot be guaranteed. For this reason, Microsoft will not push Windows 10 Mobile updates for these devices. Unlike Windows Phone 7, this time users can experience Windows 10 Mobile on their mobile phones, and there is little reason to complain about it.
