Key Difference: Nokia has recently announced its new flagship phone the Nokia Lumia 925. The phone comes with a 4.5-inch AMOLED capacitive touch screen which takes up a good amount of space on the front, with the speaker and sensors on the top. The 4.5-inch capacitive screen has the same PureMotion HD+, ClearBlack that is found in Lumia 920. The Blackberry Z10 is the latest smartphone that has been released in January 2013 by Research in Motion. The Z10 is a bar phone that is available with a 4.2 inch capacitive touch screen that has approximately 355 ppi pixel density, providing a clear and sharp display. If supports a 1.5 GHz Dual-core Krait, 2GB RAM with 16 GB internal storage capacity and expandable capacity up to 64 GB.

Nokia has recently announced its new flagship phone the Nokia Lumia 925. This phone is in lines with the other new Nokia Lumia 928, but differs from its cousin in many ways. The Nokia Lumia 925 was also known as “Catwalk” phone for a long time before it was officially announced. The company has maintained a similar design to its Lumia phones but has added a metal band. This is the first phone that will feature a mix of plastic and metal. However, the back is still made of polycarbonate plastic. The phone is made slim and light weight making it comfortable to hold. The phone’s frame is made of aluminum with only the back made of plastic. However, the back is non-removable so the battery is not easily accessible.

The device is available in black, white or grey, so don’t look for the bright colors that are expected of other Nokia phones. The phones comes with a 4.5-inch AMOLED capacitive touch screen which takes up a good amount of space on the front, with the speaker and sensors on the top and the three capacitive buttons (Home, Back and Menu) on the bottom. Similar to the other high-end Lumias, the top of the device holds audio jack, the microUSB port and the SIM slot. The left and the bottom side of the device is bare, while the right side has the volume rocker, the power button and the dedicated camera button making it a little too crowded.

The 4.5-inch capacitive screen has the same PureMotion HD+, ClearBlack that is found in Lumia 920. The ClearBlack technology plus the HD OLED screen offers sharp, clear images and also spectacular viewing in sunlight. The phones provides a good contrast and vibrant colors but the difference is not really that apparent when using day-to-day.

Under the hood, the phone is powered by Dual-core 1.5 GHz Krait Qualcomm MSM8960 Snapdragon, the same processor used in Lumia 920 and 928. The processor is fast and responsive, but lags when it comes to camera. The phone comes with Adreno 225 and 1 GB RAM, compared to the 2G found in its competitors. The phone comes with only 16 GB internal memory and does not offer users to extend it using an external card. The phone integrates the Windows Phone 8 OS, which works seamlessly. However, again similar to all other Windows Phones, the app stores lack many apps and still has yet to reach its potential.

The phone comes with an 8.7MP rear camera and a 1.3MP front camera. The camera comes with upgraded technology that uses a 1/3'' sensor size to take more high-res photos. The camera also comes with Nokia’s Smart Camera technology that allows taking 10 photos at once, which can then be altered to create the perfect photo. This is similar to the Zoe technology found on HTC One that takes mini videos along with photos. The company has also added an additional lens on the five-lens that allows taking much better photos.  Nokia also boasts about its low-light imaging technology that allows users to take excellent photos in low-lighting conditions. The imaging technology is quite superior and does take excellent images with less blur. However, the camera shutter is quite slow which requires the user to hold the phone with a steady hand to eliminate motion blur.

The company also has removed the built-in wireless feature to cut down on the weight, but has added it as an option by purchasing the wireless cover. The phone comes with a non-removable Li-Ion 2000 mAh battery that allows the phone to go longer periods of time without requiring charging. The phone also comes with a few nifty features that make it stand out. The new phone is slick, thin and has decent features. It could just be phone that turns the tide in favor of Nokia Windows Phone.

Blackberry Z10 is the latest smartphone that has been released in January 2013 by Research in Motion. The phone is powered by the company’s BB10 and is believed to be the company’s latest attempts to capture the smartphone market. The Z10 is a bar phone that is available with a 4.2 inch capacitive touch screen that has approximately 355 ppi pixel density, providing a clear and sharp display. The phone is also light in weight and perfect for one-hand operation. If supports a 1.5 GHz Dual-core Krait, 2GB RAM with 16 GB internal storage capacity and expandable capacity up to 64 GB. The Z10 has an 8MP auto-focus camera along with 2MP front-facing camera for video conferencing. The camera offers a new Time Shift mode that allows users to pinpoint and adjust individual elements of a picture.

The users can interact with the OS using gestures such as swipe, tap, pinch, and reverse pinch. The phone comes with a few new features such as Hub, Balance, Story Maker and Remember. The Hub is a screen that is available by swiping left after the first menu page and task switcher and it is creates a single point where the user can check all updates from SMS, e-mail to facebook notifications. It also offers the users to post messages, update twitter, facebook and any other services. BlackBerry Balance is a feature that allows people to separate their work life from their personal life. It allows easy access to creating two separate profiles, where work related and personal related profiles can be kept separate and maintained. Story Maker is an app that allows users to create a story by selecting photos and an audio clip to go along with it. The app will automatically create a video and will also include effects. The new keyboard on the Z10 has an adaptive feature that learns as the user types words and also suggests future words that can be used making typing e-mails and messages easier. Many reviews do state that one of the downfalls of the phone is the camera as well as lack of apps. The camera is not as sharp as it could be and the phone does not offer many apps in the BlackBerry World store.

The information for the detailed table about the two phones has been taken from the Nokia website, Blackberry website and GSMArena.com.
