Samsung has launched some of the post popular Android handsets of all time, with its Galaxy S series — which includes the Galaxy S II and the Galaxy S III — selling more than 100 million units. But the devices certainly aren’t popular for their build quality.

All of Samsung’s devices are made of plastic, and although they look good, they don’t feel anywhere near as nice as competing handsets like the iPhone 5, the Nexus 4, and any of HTC’s high-end Android handsets — particularly the new HTC One — which use materials like glass and aluminum to provide a premium feel.

But Samsung isn’t about to change that for the upcoming Galaxy S IV. The Korean company has confirmed it will continue to use plastic, and it has its reasons for doing so.

A security flaw that allows users to bypass lock screen security and briefly access the home screen has been discovered on the Samsung Galaxy Note II. The hack was discovered by Galaxy Note II owner Terence Eden, who stumbled across it simply by playing around with his device.

We’re all eagerly anticipating Samsung’s Unpacked event on March 14 in New York City, when it will announce the Galaxy S IV, its flagship smartphone for 2013. But to ensure you’re suitably excited, the Korean company has published a cheesy new teaser video. Check it out below.

With the Galaxy S III and Galaxy Note II, Samsung introduced a ton of gimmicky features in an effort to impress us. Some of them just don’t work all that well, but others, such as Multi-Window, are pretty useful.

Another feature that’s become quite popular is called SmartStay, which uses the front facing camera to detect when a user is looking at the display. This allows it to keep the display on when their eyes are on the screen, and then turn it off when they look away, conserving previous battery life.

Unfortunately, Smart Stay is exclusive to Galaxy devices, but there are third-party alternatives you can use on your devices. Here’s how to set up one of them called SmartStay Ex.

BARCELONA, MOBILE WORLD CONGRESS — I’ve used both the original Galaxy Note and the Galaxy Note II for fairly lengthy periods, and although I’ve quickly gotten used to their super-sized displays, there was one thing that never failed to frustrate me. Samsung didn’t make the capacitive buttons beneath the display compatible with the S Pen, so when you’re working with the stylus, you have to move it out of the way and use your fingers to go back or access a menu.

Sure, it’s only a small flaw, but it’s still a frustrating one — as I’m sure anyone who’s ever owned a Galaxy Note will tell you. Thankfully, Samsung has fixed this with the new Galaxy Note 8.0.
