Sony has been stepping up its smartphone options beginning the year with Sony Xperia Z1s. The device features a 20MP camera. The device is exclusive to T-Mobile at the moment. Other features include waterproof capabilities, 5-inch 1080p and faster processor. For users looking for a fast phone for gaming or multimedia playback then Z1S can be a great choice. With the release ahead of Samsung's Galaxy S5 and Apple's iPhone 6, can Sony gain a good lead?

Tech giants, Samsung and Apple, will also release their flagship phones this year. While smartphone wars have revolved around Samsung's Galaxy Series and Apple's iPhone, players like Sony are starting to release comparable devices.

The Xperia Z1S weighs 5.71 ounces and measures 5.74 by 2.79 by 0.31 inches (HWD). It is heaver and bigger compared to its predecessor. Despite the size and weight, Sony manages to make it attractive. The device features glass front and back panels. It also comes with an IP58-rated waterproof coating supporting finger tracking when in water. Other features include a black plastic and smoked silver band surrounding the edges.

The left side sports the microSD memory card slot and a covered charger. There is a center-mounted docking port. The bottom edge features the mic and speakerphone. The right side, on the other hand, has the circular power button, covered SIM card slot, camera shutter and volume rocker. There is also a 3.5mm headphone jack.

Sony packs the Xperia Z1s with 5-inch, 1080p Triluminos display. This offers sharp resolution and pixel density of 441ppi. However, users should not expect the device to be as bright or vivid. It cannot compete against the AMOLED display of Samsung's Galaxy S4. HTC One is also brighter compared to the Z1. The device also features a noticeable bezel on top and at the bottom. There is also a thinner bezel on both sides of the display. This is the reason why people will find the handset unusually tall.

People will find it easy to type on the on-screen keyboard. Best keep the device in portrait mode to see how it feels.

The Xperia Z1s offers HSPA+42 and LTE support. Other features include 802.11a/b/g/n/ac Wi-Fi on the 2.4GHz and 5GHz bands, Bluetooth 4.0 and NFC.
