The Xperia Z1S is Sony’s first smartphone launch since it took over the company from its former partner, Ericson. Sony and T-Mobile almost got it right with the Z1S.

The phone is built with remarkable technology: a 20 M camera, a 5” screen with 441 pixels per inch (ppi) pixel density, and a quad core 2.2 GHZ Snapdragon 800 processor. Not forgetting, of course, that it is waterproof.

The Z1S, though gorgeous, is a late entrant to the 5” competition and its competitors may come better recommended because of a few design hiccups that the Sony smartphone has come with. The unveiling of the Samsung Galaxy S5, which is coming very soon does not make things better for the Z1S either.

AT 6 ounces and 5.67” x 2.91” x 0.33”, the Z1S looks very different from the Samsung Galaxy S4, LG G2, HTC 1 or the iPhone S5. It is a little bigger and heavier than the other 5” screen phones.

Most of the ports and jacks on the phone have are covered by a flap and there is always a quick reminder to keep the covers closed in order to secure its waterproofing every time you awaken the phone with open flaps.

The on/off button has cleverly been placed around the middle of the right perimeter which makes it easy to to awaken it when holding it, lifting it, or balancing it on your hand.

The volume button is also right below the on/off switch, making it easy to use during a call.

Unlike the Samsung Galaxy S4 waterproofing, the Z1S is only waterproof in fresh water. The camera closes after 20 seconds under water and the phone goes back to the latest open application.

The smartphone’s power cell can last 13 hours of talk time and power saving modes can lengthen this further.

The Sony Z1S is a unique 5” smartphone and its rear camera resolution is the second highest in the market. Although the camera takes poor indoor shots, the 5-inch screen and waterproof features are one of its best selling points.
