Update August 2016: Windows Phone 10 update was released around March 2016 but Xolo Win Q1000 hasn’t yet received the Windows 10 update, the Upgrade Advisor still shows the same message “device is eligible” but it’s just another of Microsoft’s goof ups, even checked the Phone Update option in Settings it shows the device is up to date, so it’s safe to conclude Xolo Win Q1000 will not be getting the Windows 10 upgrade.
Yes!!! It’s hard to believe that a phone which I bought for ₹5,999/- is eligible for the latest Windows 10 Upgrade. The Xolo Win Q1000 is actually Blu Win HD re-branded by Xolo. Blu Win HD was launched in 2014 and it’s eligible for the latest Windows 10 Upgrade. There was confirmation that Blu Win HD LTE version will be upgradeable to Windows 10 but there was no confirmation on Blu Win HD/Xolo Win Q1000 upgradeability but now it’s confirmed, when the upgrade will be available is not yet confirmed.
Update: It’s been months still haven’t received Windows 10 update and it’s highly unlikely that the update will ever arrive on this device.
