(Telecompaper) Opera Software announced that the Opera Mobile Store will replace the Nokia Store as the default app store for Nokia feature phones, Symbian and Nokia X smartphones, following an agreement between Opera Software and Microsoft. Beginning in the first quarter of 2015, the Nokia Series 40, Series 60, Symbian, Asha and Nokia X devices will be automatically redirected to Opera Mobile Store. Thi sis the latest step in Microsoft's rebranding of the Nokia mobile phone business, ahead of the expiry of its licence to the Nokia name in 2016. The process of migrating customers to the Opera Mobile Store is expected to be completed in the first half of 2015, at which point the Nokia Store will be closed. Opera said this will make it the third-largest app store in terms of downloads. Its store already offers close to 300,000 apps and games and records millions of downloads each day. The store supports apps for more than 7,500 different devices, from feature phones to advanced smartphones. The announcement follows a separate agreement, announced in August 2014, which will see Opera become the default browser on Nokia-branded phones, including Series 30+, Series 40, Asha and Nokia X handsets.
