Key difference: Sony Xperia P features a 4-inch TFT touch screen that allows up to 4-touch capabilities. The screen is scratch resistant and has a shatter proof coating. The touch screen provides approximately 275 ppi pixel density along with WhiteMagic technology, which adds an extra white pixel with the already present red, blue and green. The Nexus 4 is Google's fourth Nexus-branded Android smartphone. It was produced in collaboration with LG Electronics. The phone runs on the Android 4.2 (Jelly Bean) operating system, which was launched with the phone.

 Sony is a prominent technology company and is known best for its electronics such as phones, TVs, gaming systems, etc. The constant dynamic nature of technology ensures that we always have a better and more forward technology than the one we had a month ago. The price of this dynamic technology is also high, the constant updating of technology requires people have that much cash on hand. However, many companies such as Sony know that not many people have that much cash on hand for disposal, hence has launched mid-range phones such as Xperia P that allows the people to experience the best of both worlds: technology and affordable pricing. The Xperia P was launched in May 2012 and continues to be a major player in the market.

Sony Xperia P features a 4-inch TFT touch screen that allows up to 4-touch capabilities. The screen is scratch resistant and has a shatter proof coating, allowing the screen to endure minor scratches and everyday scuffs without sacrificing on the quality. The touch screen provides approximately 275 ppi pixel density, though not the best ppi compared to the heavy contenders but the quality of the screen is not sacrificed. This is mostly because of the company’s WhiteMagic technology, which adds an extra white pixel with the already present red, blue and green. The extra pixel generates a higher level of brightness that does not cloud the phone when using it under direct sunlight.

The phone is a little bulky in nature, but it is easy to become accustomed to when holding it for longer periods of time. The phone is also a little heavier compared to similar phones, but again not something that lets the user forget of the other great features of the phone. The phone is encased in a plastic chassis, which is quite smooth to hold but is also prone to many visible scratches and chips. The device has a clear plastic border on the front that also doubles as a cover up for the antenna. Above the plastic border reside buttons Home button, back button and Menu button. The power button, the volume rocker and the physical camera button is on the right side of the device, while the left sides hosts a variety of ports including the SIM card slot.

Under the hood, the device is powered by 1 GHz Dual-core processor and hosts the company’s Timescape UI. The user interface is quite smooth and does not glitch when shifting between the screens and the apps. The device runs on 1 GB RAM and comes with an internal storage capacity of 16 GB. Of the 16 GB, only 13 GB is available to the user and it is not expandable. The device houses an 8 MP Autofocus rear camera and a VGA (0.3 MP) front camera, which is a little bit of a letdown. The Exmor R technology ensures that the rear camera provides sharp, clear images, while the front camera does not live up to the same quality.  Though initially powered by Android v2.3, the device is now available with Android v4.0, which no status as of yet for v4.1 upgrades. The phone also comes with additional features such as Motion gaming, MobiSystems’ OfficeSuite 5, Wi-Fi hotspot, DLNA, USB On-the-go, Native USB tethering and NFC capabilities. The Xperia P houses a non-removable 1305 mAh battery, which provides a decent battery life and lasts almost a day. With the amount of features that are offered with the phone, the price tag is expected to be quite high; however, the price is quite affordable and will not make that much of a dent in the user’s pocket.

A number of these companies’ smartphones and tablets run on Android. Android is an open source software, which means that the code is freely available for modification and distribution by device manufacturers, wireless carriers and enthusiast developers. Among the number of various companies, Google has also launched its own line of smartphones based on Android, called the Google Nexus. Each device in the Nexus line is produced via collaboration between Google and a leading original equipment manufacturer (OEM) partner.

The Nexus devices in general have an advantage over other devices in that the Android in the Nexus devices is pure, i.e. the Android does not have any manufacturer or wireless carrier modifications to it, such as a custom graphical user interface. The Android also has an unlockable bootloader to allow further development and end-user modification, all of which is usually blocked on other Android smartphones.

The Nexus 4 is Google's fourth Nexus-branded Android smartphone. It was produced in collaboration with LG Electronics. The phone features a 1.5 GHz quad-core Snapdragon S4 Pro processor, 2 GB of RAM, 8 or 16 GB of internal storage, front facing 1.3 megapixel camera and an 8 megapixel rear camera and a micro-SIM card tray. The phone runs on the Android 4.2 (Jelly Bean) operating system, which was launched with the phone. The phone also features a new camera technology, called the Photo Sphere. This allows one to take 360 deg Panorama shots.
