Microsoft's Lumia Cyan and Windows Phone 8.1 updates were scheduled to start rolling out to Lumia 720 users in India only in September 2014. However, they are already available to Lumia 720 smartphones in the country before the scheduled date.
According to a Nokia Power user report, Lumia Cyan has already started rolling out for owners of Lumia 720 Windows Phone users in India, along with Lumia 530 users in the country.
Also, various users of Lumia 720 via Twitter have reported to having installed both the Lumia Cyan and Windows Phone 8.1 upgrades.
With Lumia Cyan having reached Lumia 720 users in India, Microsoft seems to have released the upgrade earlier than its previously announced September rollout.
Both the Lumia Cyan and Windows Phone 8.1 upgrades had earlier reached countries like Australia, New Zealand (for all Lumia smartphones), Canada (for Lumia 625 users), apart from India (Lumia Cyan is expected to roll out this week in the country).
One enhancement that users generally look forward to in the Windows Phone 8.1 update is Microsoft's personal digital assistant Cortana; however certain Lumia users (in India) have reported on Twitter that the PDA is yet to make herself available in the country.
The Windows Phone 8.1 update also features Microsoft's Internet Explorer 11 web browser, a customisable lockscreen, pull down notification bar and an extra 'live tiles' column (optional) on the homescreen.
On the other hand, Lumia Cyan is a firmware upgrade and is applicable to Lumia smartphones only. This update brings camera and camera roll enhancements to Lumia smartphones.
With the Lumia Cyan update, owners of Lumia smartphones can save games and applications directly to a microSD card.
Lumia 720 users should observe the Lumia Cyan/Windows Phone 8.1 upgrades being available to them, via over-the-air (OTA) mechanism and can also check and install these updates manually.
Users can navigate to the Settings menu within their Lumia smartphones, to check and install the Lumia Cyan/Windows Phone 8.1 updates.
