The Mobile World Congress 2015 that took place in Barcelona, Spain has just come to an end and the biggest launches and stories are still going viral.

Undoubtedly, the most important launches were the two new smartphones from Samsung: their brand-new flagship, Samsung Galaxy S6 and their curved edged handheld device, the Samsung Galaxy S6 Edge.

The Samsung Galaxy S6 has a redesigned metal case, the first metal case for the Samsung Galaxy S series, an upgraded 577 pixels per inch QHD screen and it comes preloaded with the latest Android operating system, the Android 5.0 Lollipop. Cameras, the front and the back one, were improved in both models.

HTC also launched their new flagship smartphone, the HTC One M9. The new smartphone offers many improvements of the predecessor, the HTC One M8, such as a 20MP rear-facing camera perfect for selfies and an octa-core Snapdragon 810 chip.

Even though Sony also had some launches (the Xperia Z4 Tablet and the Xperia M2 Aqua), it disappointed a lot of people by not launching their eagerly-awaited Sony Xperia Z4. When asked about why the company didn’t release their new flagship smartphone, Pierre Perron, the company’s vice president for Western Europe, said that they didn’t want to rush out a new smartphone just for the sake of it.

Microsoft also did not bring their A-game to the table, as they launched a mid-range Nokia Lumia 640 and Lumia 640 XL.

Smartphones weren’t the only devices that caught people’s attention at the Mobile World Congress 2015. Intel unveiled its new Atom X7 SoC for tablets and 2 in 1s, which is going to power devices that run full versions of Android and Windows.

Qualcomm revealed their new next-generation Snapdragon 820 chip, its ultrasonic Snapdragon Sense ID 3D Fingerprint technology and LTE-U plans.

About the Fingerprint technology, Qualcomm says that it will outperform the scanners on iPhone 6 and the Galaxy S6 thanks to its sound-driven technology that can scan fingerprints through any metal (be it glass, metal or sapphire).

Huawei unveiled their Huawei Watch, the event’s biggest surprise and Fujitsu revealed the first smartphone iris scanner that will debut on devices at the end of 2015.
