Could the Windows Phone soon be removed from the market? This is the question many people are asking after the sales of the Lumia fell by more than 50 percent in the last quarter of 2015.

PC World reported that Lumia smartphones cut its sales by more than half for last year's quarter compared to its earnings during the fourth quarter of 2014.

Microsoft reportedly announced last week that only 4.5 million Lumia phones were sold by the company for the last quarter of 2015, a 57 percent fall from the 10.5 million units sold during the same period in 2014.

The same report also mentioned that the phone revenue also dipped by 53 percent, equivalent to $1.2 billion.

But the worst is not over yet, as the company's chief financial officer Amy Hood noted that their revenue on phones is still expected to fall this quarter.

In addition, BGR said this is a sign that Microsoft cannot compete with other tech giants and smartphone makers like Apple.

It added that the company is now struggling in the market after being present for around nine years now.

Microsoft, as per the BGR report, has not been able to really make a name in the smartphone market, since it was not able to live up to the competition that Apple and Android smartphones had to offer.

"What matters now is that Microsoft's effort with Windows Phone has been nothing short of an abject failure," added the same report.

Agreeing to this, Beta News claimed that the Windows Phone did not become relevant enough for it to be called "truly alive."

It added that the sales of Microsoft's products did not pose a threat to the Apple line, which remained a leader in the market. The difference in the smartphone market is huge, even with tight competitors, as per Beta News, 

"It is extremely hard for any vendor to make it in this crowded market, and it is even harder -- if not impossible -- to make a splash with an operating system other than Android powering your devices," noted the same report.

The decline in sales was also attributed to the failed flagship releases and the length of the waiting period for another phone to be released.

But despite this decline in sales, Hood told Computer World that the fall in the Windows revenue can be considered "smaller" in terms of percentage than the PC industry.

"Our total original equipment manufacturers (OEM) business declined 5% this quarter, outperforming the overall PC market," Hood added.
