Samsung Galaxy S7

Samsung traditionally unveils the latest of their flagship Android Galaxy S Series of smartphone here, and on February 21, the company is having a "Galaxy Unpacked" 2016 press event.  It is expected that the Galaxy S7 and the S7 Edge will be announced here according to Ars Technica.   

According to The Verge, we know that the Galaxy S7 Edge will have a 3,600 mAh battery, thanks to an FCC filing.  That is much larger compared to the 3,000 mAh battery on the Note 5.  It is also rumored that the S7 Edge could have a larger screen size than the regular S7, even though the 2015 versions of the S6 and the S6 Edge had a display that was equal in area. 

It is difficult to tell if the rumors about reducing the 16 Megapixel sensor for a 12 Megapixel sensor is true.  There is also a report that the S7 and S7 Edge could have some serious waterproofing, and it will support a microSD storage.  Other rumored features include its own version of Apple's 3D Touch screen, an eye-scanner, and USB Type C connector port.

HTC One M10

Unlike the other phones mentioned above, HTC doesn't have any confirmed phone that will arrive at MWC 2016, but the latest model is surely on the way.  Recent rumors of the device on Phone Arena has shown that the screen size could receive an upgrade.  Not only could it be 5.1 inches, but it could go as high as 5.2 inches, almost bringing it into phablet territory.  The resolution will be the same at 1440 x 2560 (QHD) resolution as well as Snapdragon SoC on the inside.  There could be some changes in store for the HTC One M10, like no stereo speakers, no HTC logo on the front, and a fingerprint scanner on the bottom of the phone's face.
