Here at Fueled, a design and development company based in New York and London, we are obsessed with everything that happens in mobile, be it rumors of iPhone hardware, delectable Android updates or new apps we love.

Every Friday, we’d like to help you “top up” your weekly knowledge of the mobile industry so you can keep your finger on the pulse.

Galaxy S5

Samsung showed off its latest Galaxy installment at the Mobile World Congress in Barcelona on Monday. The new Galaxy S5 boasts a 16-megapixel camera, a faster processor, and a fingerprint sensor. The downside? It's heavier and a bit thicker than expected, but it's still getting rave reviews. via WSJ

Nokia's 3 New Androids

Nokia introduced three new Android phones at the Mobile World Congress under its "Nokia X" brand and OS. This was a noted departure from Nokia's previous reliance on Microsoft's Windows Phone 8 operating system. Microsoft, apparently, is not pleased with the change with one Microsoft employee calling it "embarassing." via Business Insider

New Blackberry

Also in Barcelona this week, Blackberry unveiled a $200 smartphone in an attempt to win back customers in emerging markets. Many consumers in these markets are gravitating towards phones operating on Google's Android system. The device's name is Jakarta. via Business Insider

Gear Fit

Samsung also debuted on Monday in Barcelona its own fitness tracker, the Gear Fit. The band has an attractive 1.84 inch curved touch screen, a heart-rate sensor and pedometer. It can also sync with Samsung phones and has triple the battery life of the Galaxy Gear. It looks good, but it doesn't really do much. via NYT Bits

Sony's Smartband

Sony's latest creation is the Smartband, the first product powered by Sony's new Core fitness tracker. The band will be released worldwide next month. Sony showed off the bracelet at the Mobile World Congress but not as just a fitness accessory. With an accompanying app, the device will track your physical activity but will also keep track of songs you've listened to, places you've visited and friends you've seen. via The Verge
