Nokia confirms software bug in its recently launched Lumia 900 Windows Phone smartphone that prevented users from connecting with the network. The mobile giant is compensating user’s sentiments with a credit of $100 to all Lumia 900 owners even if some of them are not affected by the bug. The $100 will be automatically credited to AT&T customers’ bills and will be effective for any other potential buyers too who buys the phone by April 21, 2012. On a two-year data contract the cost of the phone was calculated to $100 on AT&T network. With this $100 credit by Nokia, the cost of the Lumia 900 hence becomes zero, which means free for early adopters. According to Nokia, the data bug is due to memory management issue and is only related to software, not the hardware part or to AT&T’s network. Fixing the problem at users end is easy. One can swap the phone at an AT&T store or can download an updated software through Zune on or around 16th April. Both AT&T and Nokia are putting the handset to a great hype with few huge marketing campaigns such as a series of TV commercials featuring Chris Parnell and promotion in Times Square. A report published on Ad Age, AT&T is spending $150 million on a Lumia 900 campaign with a theme “the smartphone beta test is over.” Unfortunately, the slogan betrays its meaning in the light of the phone’s launch bug. Well, Nokia managed to turn bad name down by granting credits to users and getting even more promotion thereafter for so far one of the best Windows Phones.
