Two years ago Motorola’s Android –in- WebTop -Operating system was kicked off the stage by ASUS’s PadFone as it was the world’s first phone that could fully power a tablet module by its own operating system. ASUS took a period of two years for materializing the idea of PadFone but finally it has come up with the one. ASUS started manufacturing the PadFones five months ago with the launch of PadFone but now they have launched PadFone infinity that is non- surprisingly the full HD update for both the phone and tablet module. This smartphone has a new 1.7 GHz- quad core Snapdragon 600 SoC alongwith a new aluminum brushed body. Alike many of the recent flagships, the PadFone comes with a 5-inch 1080 display and a quad core chip. A significant upgrade has been done in the screen from the earlier launched PadFones. PadFone infinity has a greater built-in battery of 2,400 mAh. The main camera installed in this smartphone uses the Sony 13- Megapixel IMX091 as a sensor and the focal length of lens is f/2.0. It has a 2 megapixel front facing camera for video calling as well. It has been designed in a whole new manner as it has been provided with an aerospace grade and twice anodized aluminum alloy construction. This smartphone has fully metallic body along with a vertical brush pattern across its back which is so much curved that when it is viewed either from the top or bottom the thickness varies from 8.9 mm in the middle to about 6mm at the edges. The gentle curve provided on the back of this smartphone does not allow the user to comfortably hold it but it is dead at the straight sides and due to it produces relatively sharp edges. The back has a straight brushed metal pattern that makes it a versatile phone with solid feel and clean look. At the top of this smartphone there is camera as usual and an LED light. The back side of this smartphone alone makes this device the best ever made by ASUS. In the front, there is the protruding and scratch resistant screen Corning screen lens covering almost the entire surface. The four sides of this smartphone have similar finish as 6the back be it titanium grey, hot pink or champagne gold. The loudspeaker of this smartphone is situated on the right hand side just above the power button and volume rocker. The top and bottom sides of this smartphone have well- disguised polycarbonate due to which proper reception is enabled through an all metal body. The top edge has been provided with a 3.5 mm headphone jack, whereas the microphone and micro- USB socket lies at the bottom. The only drawback of this smartphone is that it does not have a slot for memory card expansion, therefore you will have to choose between the 32 GB and 64 GB models quite carefully. The PadFone station of Infinity uses a docking retention system that involves separated silicon grips that hold onto two vertical sides of the phone.
