The HTC Butterfly is a high-end phone by the HTC Corporation. The phone has been quite popular all over the world; however, most people don’t know exactly how popular the phone has actually been. This is mainly because not many people know that the HTC Butterfly and HTC Droid DNA is actually pretty much the same phone, with only a few differences. The differences are only there to make the phone more regional specific.

The HTC Butterfly is sold in four variants: Droid DNA in the United States on the Verizob Network; J Butterfly HTL21 in Japan on KDDI's au network; Butterfly X920d in Taiwan, South East Asia and India; and Butterfly X920e in China and Russia.

All the variants have most of the same features. They are all powered on a Quad-core 1.5 GHz Krait processor. The HTC Droid has the Quadcomm MDM615m, while the Butterfly variants have the Qualcomm APQ8064 chipset. They all have 2 GB of RAM and Adreno 320 graphics processor. They all have an 8 MP primary camera and a 2.1 MP secondary front facing camera. The display is a 5 inch Super LCD3 capacitive touchscreen with Corning Gorilla Glass 2. At the time of the launch the phone was the second phone in the market to feature a 1080p display. The phone has Android version 4.1, but is upgradable to Android 4.2.

The HTC Droid DNA differs from the other variants, in that it supports wireless charging, but lacks a MicroSD slot. The Droid DNA and the J Butterfly both support CDMA and LTE connections, as well as UMTS. However, only the Droid DNA comes with quad band UMTS radio. The X920d and X920e, on the other hand, do not even have LTE support. There are also some subtle differences regarding color accents, buttons and logo placement. However, these are minor and so not affect the phones.

The 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. It 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.
