According to foreign media reports, Nokia cheap cell phones sales may become more worse. Microsoft will launch a new mobile operating system Windows Phone 8 in the fall, as a fully upgraded the system can not run on Nokia Lumia phones. Therefore, a new series of Lumia smartphone sales probably will be hard hit.

Nokia has been advised to join the Android camp before it is too late for the company, considering its constantly sinking market shares and acquisition rumors being reported lately. Bernstein Research’s Pierre Ferragu is reportedly claiming that if one excludes the portion including Nokia-Siemens Networks, the company’s balance sheet is “in a rather tight net cash position,” and its stock is overvalued.

Nokia has been losing its  phones market to other vendors for quite some time now. While the recent alleged merger rumors did help the company’s shares to go up by a few percent, its shares starting falling back soon after the rumors died. Nokia’s association with Microsoft for Windows Phone operating system is considered to be the main reason behind its dipping sales and shares. Moreover, Nokia’s lower-cost feature phones in the “Asha” line have also not done any good for the brand either.

Nokia's partnership with Microsoft has been anything but what either company was hoping for, even if recent signs are encouraging. The Finnish phone maker and the Windows Phone operating system found on many of its devices are struggling to make the smartphone the three-horse race Elop was talking about when unveiling the new strategy.

Nokia continues to rely heavily on its feature android os phones sales to keep finances in check, as evidenced by its most recent ad campaign for the S40-powered Nokia Asha 501. But the featurephone market, once a pillar of Nokia's dominance, is also starting to crumble. Even in the conservative Western European smartphone market, where Nokia's total shipments have dropped by 30% year-over-year.

Nokia is readying a Windows Phone-running version of its 808 PureView 41-megapixel monster. It's set to announce the Lumia 1020 at an event in New York on 11 July. But it's not the only one with a next-gen camera phone up its sleeve. Samsung has already unveiled the Galaxy S4 Zoom, and Sony's Xperia i1 Honami is rumoured to pack 20 megapixels.

Do you think Nokia should start using Android? Will it? And who do you think will have the best camera phone out this year? Let me know in the comments.
