If you are currently a Windows Phone 7.8 user and quite comfortable about it, this piece of information affects you. Accroding to reports, Microsoft has announced that it will stop support for Windows Phone 7.8 starting September 9.
Making it very clear that users on Windows Phone 7.8 will soon need to move on to newer pastures, Microsoft has revealed that Windows Phone 7.8 will only have an 18-month life cycle, meaning "mainstream support" will end for the OS on September 9, 2014.
"Microsoft will make updates available for the Operating System on your phone, including security updates, for a period of 18 months after the lifecycle start date," Microsoft states.
"Distribution of the updates may be controlled by the mobile operator or the phone manufacturer from which you purchased your phone. Update availability will also vary by country, region, and hardware capabilities."
So this means that phones that are on the older OS will continue functioning with no problems for the operation. However, unlike Android phones which get upgrades and updates from third-party developers, those who want to receive updates from Microsoft would have to make way for their older handsets for new ones.
As of now, Windows Phone 8.1 is set to receive a 36-month update period, until July 7, 2017.
