Hardware manufacturers are constantly trying to release feature packed but stylish smartphones to consumers, but designers often come up with some great concept ideas and today we have a Microsoft Surface and Facebook phones that are not reality impossible.

Today we have two more concept smartphone ideas for you that are not impossible to make a reality, as all it takes is time and the correct materials to make them viable and affordable enough for consumers. First up on Concept Phones we have the Microsoft Surface Phone that has been created by Antonio Celestino from Brazil.

The handset features two HD touchscreen displays with one on the front and the other on the back, and the handset has a rounded profile with fully integrated bumpers to prevent both screens touching the ground. The concept has a new take on multitasking as once you rotate the handset it will open up another task. Other specifications include eight megapixel cameras on the front and back, while the body is only 8mm thick.

Meanwhile Michal Bonikowski has created a great looking Facebook phone concept before and now as Concept Phones are reporting he has come up with something new. Using his old design but with some modifications Bonikowski imagined what the handset would look like if HTC had made it.

There is a dedicated Facebook button that doubles as a home button, and it looks to have a nice metallic back possibly of aluminium. There is also a camera with a built in flash with a nice looking earpiece area at the front. The handset design features a lot of metal that is a move away from the plastic handsets that seem the norm lately.

Specification wise the handset could feature a 4.5-inch HD display powered by a dual core Snapdragon S4 CPU clocked at 1.5 GHz, 8 or 16GB of storage, and a revolutionary Facebook cloud storage service that could offer 100GB considering the size of the site’s servers.
