NFC is a short-range high frequency wireless communication
technology that enables the exchange of data between devices over about a 10 cm
distance. Near field communication (NFC) is a set of standards for smartphones
and similar devices to establish radio communication with each other by
touching them together or bringing them into close proximity, usually no more
than a few centimeters. Present and anticipated applications include
contactless transactions, data exchange, and simplified setup of more complex
communications such as Wi-Fi. Communication is also possible between an NFC
device and an unpowered NFC chip, called a "tag”.
NFC is an upgrade of the existing proximity card standard
(RFID-radio frequency identification) that combines the interface of a
smartcard and a reader into a single device. It allows users to seamlessly
share content between digital devices, pay bills wirelessly or even use their
cellphone as an electronic traveling ticket on existing contactless
infrastructure already in use for public transportation.
The significant advantage of NFC over Bluetooth is the
shorter set-up time. Instead of performing manual configurations to identify
Bluetooth devices, the connection between two NFC devices is established at
once (under a 1/10 second).
Due to its shorter range, NFC provides a higher degree of
security than Bluetooth and makes NFC suitable for crowded areas where
correlating a signal with its transmitting physical device (and by extension,
its user) might otherwise prove impossible.
NFC can also work when one of the devices is not powered by
a battery (e.g. on a phone that may be turned off, a contactless smart credit
card, etc.).
Uses (Elaborated)
NFC builds
upon RFID systems by allowing two-way communication between endpoints, where
earlier systems such as contactless smart cards were one-way only. Since
unpowered NFC "tags" can also be read by NFC devices, it is also
capable of replacing earlier one-way applications.
Commerce
NFC devices
can be used in contactless payment systems, similar to those currently used in
credit cards and electronic ticket smartcards, and allow mobile payment to
replace or supplement these systems. For example, Google Wallet allows
consumers to store credit card and store loyalty card information in a virtual
wallet and then use an NFC-enabled device at terminals that also accept
MasterCard Pay Pass transactions. Germany, Austria, Finland, New Zealand, and
Italy have trialed NFC ticketing systems for public transport.
India is
implementing NFC based transactions in box offices for ticketing purposes.
The Galaxy Grand is mostly about having a big screen at an affordable price. The screen is not HD, it is not a high-resolution display, but instead to arrive at that price Samsung had to pick a WVGA, or 480 x 800-pixel panel. That works out to a pixel density of around 186ppi, which is far from retina and decisively mid-range, so you’d be able to see some jagged edges on icons. Under the hood, the Samsung Galaxy Grand runs on a 1.2GHz dual-core processor of unknown breed, and on the back there is a capable 8-megapixel camera. Good news is there is little shutter-lag and start-up is allegedly quick. The camera features backside illumination sensor (BIS) for better shots in low-light conditions, and it is capable of recording 1080p video. The Grand also has a front-facing, 2-megapixel camera for video calling. It all runs on Android 4.1.2 Jelly Bean, which should mean that performance is smooth lag-free with Project Butter.
Micromax is showing no sign of slowing down when it comes to the phablet onslaught, brought about by the Canvas 2 A110. The company has launched a high-end version dubbed the A116 Canvas HD, which raises the bar once again for mid-range Android, or simply smartphones in general. The A116 boasts of a higher definition screen and a more powerful quad-core CPU, something we’ve not seen in this price range till now. Its primary competition when it launches in the first week of February will be the Wicked Leak Wammy Sensation around the same price point and the just launched Samsung Galaxy Grand. Let’s breakdown the specification of the Canvas HD A116 and see how it stacks up against the competition.
Features/specs at a glance:
OS – Android 4.1 Jelly Bean The A116 will launch with 4.1 Jelly Bean right out of the box. This puts it ahead of the curb compared to other phones in this price range as well as well as some higher-end handsets. Jelly Bean brings with it Project Butter, which helps deliver a smooth UI experience as well as other enhancements like Google Now, a better camera interface etc.
Cellular network – Dual SIM GSM and 3G The Canvas HD A116 will retain the dual SIM functionality and will support GSM and 3G networks. You should be able to use both SIMs simultaneously as well, although what’s not very clear at this point is whether or not it will support quad-band or even dual-band 3G.
Display – 5-inch HD IPS Our major gripe with the Canvas 2 A110 has been addressed with the A116. Micromax has fitted the Canvas HD with a 720p IPS display, which brings the pixel count all the way up to 294ppi. This is the same pixel count as the first Galaxy Note. The Wammy Sensation has a slight edge over the A116 as it packs in the same resolution but on a smaller 4.7-inch display. The Galaxy Grand won’t be a very pretty sight since it only has a WVGA resolution at the same screen size. We’re not sure yet if the Canvas HD will have any scratch resistant glass fitted to it.
Form factor and weight – Will be a handful with nothing but a picture to go, we don’t have the official dimensions and weight of the A116, but we can safely assume it won’t be too far off from the dimensions of the A110. It does appear to be slightly thicker than the A110, but it’s quite hard to tell based on one picture alone.
Wi-Fi – 802.11 ‘n’ It’s business as usual over here. We have Wi-Fi 802.11 ‘n’ for connectivity. It’s not dual-band, but still good enough for everyday use.
SoC– MediaTek MT6589 (quad-core) - This is one area where Micromax has completely blown away the competition. The A116 features MediaTek’s MT6589 SoC, which contains a quadc-core ARM Cortex-A7 CPU and PowerVR Series5XT GPU. While the CPU uses the slightly older architecture from ARM, the SoC is built using the newer 28nm fabrication process, so it should do well in terms of power efficiency. Micromax hasn’t detailed all the multimedia capabilities of the A116, but digging a little deeper in to the chipsets capabilities, we find support for 1080p video recording. Whether or not Micromax chooses to use this is yet to be seen. Nevertheless, the four cores should easily help in gaming and even the general responsiveness of the UI. Another noteworthy feature is the inclusion of 1GB of RAM, which is on par with the Wammy Sensation and the Galaxy Grand.
Storage – 4GB onboard with room for expansion onboard storage is not much; thankfully, you have the option to expand it via a microSD card slot.
Primary Camera – 8MP sensor with LED flash The primary camera is an 8MP similar to the one used on the A110. Sadly, it’s not a BSI sensor like the one on the XOLO A800. We feel Micromax could have done a little better in this area. Still, we’ll have to wait and see how much of an improvement the camera on the A116 really is.
Front camera – VGA resolution The front facing camera is only VGA, so don’t expect a whole lot for video calls or even self-portraits.
Sensors – Accelerometer, proximityWe don’t have any details on the sensors in the A116, but it’s safe to assume that it will have a accelerometer and a proximity sensor. We hope that the Canvas also features an ambient light sensor and if we’re lucky, a gyro and a compass as well.
GPS – GLONASS and GPSMicromax has stuck with the good’ol GPS for the A116 as GLONASS is missing from the picture. We guess including that piece of hardware would have driven the cost up.
Battery – Li-Ion 2100mAh The battery size is the same as the one on the Galaxy Grand, however, the quad-core CPU in the A116 might take a toll at the end of the day. A larger battery would have been nice, but we’re guessing that would have automatically increased the weight or the dimensions of the phone.
MY conclusion:-No matter how much we try and nit-pick, there’s no denying the fact that the Canvas HD is currently the best Android smartphone, at least on paper. We don’t know if there will be any competition to the A116 by the time it actually hits retail, but it’s safe to assume that it’s going to be really tough to beat. Some of the strong points that work in its favour include an HD IPS display, quad-core CPU and Jelly Bean support. The only real area of concern right now is the battery life.
While it's great to see such a powerful handset at a reasonable price, the real question is, will people be ready to shell out more than Rs.10,000 for a Micromax? The company has undoubtedly produced some very good handsets in the past few months, but they’ve all been around the Rs.10,000. When you come to the 15K to 20K price range, things like aesthetics, quality of materials used, updates etc. tend to matter. Samsung has just launched the Galaxy Grand for an MRP of 21,500, so assuming the street price is around Rs.18,000, unless you’re on a very tight budget, a typical user would cough up the extra dough for a product from a more established company. If you had to pick between the A116 and the Galaxy Grand, which one would you go for?
Xperia tablet Z rumors started after the launch of Sony Xperia Z at CES 2013. Just two days before the launch of this tablet, we had posted about the existence of this tablet. Finally, Sony Japan officially announced the Xperia tablet Z which will go on sale in japan in the spring 2013. This tablet seems to be very good as far as the specifications are concerned. It is also water-proof and dust proof like the Xperia Z smartphone.

Android rooting is the process of allowing users of smartphones, tablets, and other devices running the Android mobile operating system to attain privileged control (known as "root access") within Android's subsystem. Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices, resulting in the ability to alter or replace system applications and settings, run specialized apps that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user. Rooting is similar to jailbreaking devices running the Apple iOS operating system. On Android, rooting can also facilitate the complete removal and replacement of the device's operating system, usually with a more recent release of its current operating system.
Rooting enables all the user-installed applications to run privileged commands that are typically unavailable to the devices in their stock configuration. Rooting is required for more advanced and potentially dangerous operations including modifying or deleting system files, removing carrier- or manufacturer-installed applications, and low-level access to the hardware itself (rebooting, controlling status lights, or recalibrating touch inputs.) A typical rooting installation also installs the Superuser application, which supervises applications that are granted root or superuser rights.
A secondary operation, unlocking the device's bootloader verification, is required to remove or replace the installed Operating System.
In contrast to iOS jailbreaking, rooting is not needed to run applications distributed outside of the Google Play Store, sometimes referred to as "sideloading". The Android OS supports this feature natively in two ways: through the "Unknown sources" option in the Settings menu and through the Android Debug Bridge
Process:
The process of rooting varies widely by device, but usually includes exploiting a security weakness in the firmware of the device, and then copying the su binary to a location in the current process's PATH (e.g. /system/xbin/su) and granting it executable permissions with the chmod command. A supervisor application like SuperUser or SuperSU can regulate and log elevated permission requests from other applications. Many guides, tutorials, and automatic processes exist for popular Android devices facilitating a fast and easy rooting process
. Why would you want to root your phone?
Rooting an Android smartphone comes with a number of major benefits. Most hardware manufacturers place major restrictions on their Android operating systems. For example, companies like Samsung
Rooting Android comes with hundreds of benefits. However, one of the most popular benefits is being able to access hundreds of new apps.
On a normal Android device, apps have to go through a rigorous certification process before they get listed on Google Play and other Android marketplaces. Certain apps are removed because they compete with apps already offered by the hardware manufacturer, while others are removed because the hardware manufacturer simply doesn’t like them.
To help you get the most out of your rooted Android device, here are the top 10 root apps currently available to users of rooted Android devices:
10) ShootMe – Screenshot app
Android has a lot of advantages over its main competitor, Apple’s iOS. However, unlike iOS, Android doesn’t give users the ability to take screenshots of their phones. Thanks to the ShootMe app available on rooted phones, that problem is a thing of the past. This app allows you to set up a trigger for when the phone should take a screenshot. For example, if you want to take a screenshot every time you shake your phone, you can easily set that up.
9) Titanium Backup – Automatic backup and recovery app
No electronic device is immune to failures. If you’re like most people, you keep some valuable information on your Android device. From phone numbers to pictures and everything in between, losing access to that data could be devastating. That’s why you need Titanium Backup, an app which allows rooted Android users to set automatic backup options. All apps and other data is saved, so if you screw up your phone while trying to install a custom ROM, you can easily restore it with the click of a button.
8) Metamorph – Customize every single aspect of your phone
After rooting an Android phone, one of the first things that many users do is customize their device. Thanks to the Metamorph app, phone customization is as easy as possible. Simply download the app, then browse through a selection of custom themes. If you want, you can even make your own theme. Using Metamorph, you can personalize your lock screen, menus, app screens, and all other aspects of your Android phone.
7) Adfree – Instant advertisement blocking
Sick of seeing advertisements on your phone? Aren’t we all! With the Adfree app, you’ll never have to see another advertisement again. The Adfree app works in a unique way: instead of actively scanning each app and webpage for advertisements (which slows down Android performance), Adfree simply blocks the IP addresses of common advertising agencies. This means that advertisements will refuse to pop up while using apps, browsing the internet, or performing any other types of tasks on your phone.
6) Busybox – Use Linux commands
Busybox might not appeal to the average Android user, but it will certainly appeal to tech geeks and Linux users. Busybox is an app that adds Linux commands to your Android device. To make the app as easy as possible to use, Busybox even lists the commands, making it easy to perform a wide variety of functions that are normally unavailable to users of non-rooted Android devices.
5) Wireless Tether – Wireless hotspot app
Share your Android phone’s data connection with any other wireless device using the Wireless Tether app. This is an ideal way to use your phone data on your laptop while you’re in an area with no internet connection, although tethering can be used for a wide variety of purposes. With the Wireless Tether app, tethering can be performed on any carrier and any Android phone. Since some companies like AT&T charge an additional $20 per month for tethering, this makes the Wireless Tether app an extremely valuable tool.
4) Tasker – Automatic task app
Tasker is a smart app that will automate all sorts of tasks on your phone. For example, you can set a task to run every day at 5pm, or perform plenty of other useful functions. Although Tasker is available from the Google Play store, it won’t have root access on non-rooted Android phones. When you give Tasker root access, expect to see some phenomenal results.
3) SSH Tunnel – Safeguard your internet usage
Instead of letting anyone see what you’re doing on the internet, the SSH Tunnel encrypts your internet connection using an SSH tunnel. When you access a public Wi-Fi network without an app like SSH Tunnel installed, anybody with basic technical skills can see what you’re doing over the internet, which is most definitely a bad thing.
2) SetCPU – Overclock and monitor your processor
The processor is at the heart of your Android phone’s operations. On a normal Android device, the user’s actions won’t affect how the CPU functions. However, thanks to the SetCPU app, that is no longer a problem. SetCPU allows users to customize the CPU to run at different frequencies according to what the user is currently doing. For example, you can instantly reduce the CPU’s clock speed when the screen is turned off, which saves an enormous amount of battery life. Ultimately, SetCPU allows you to save battery power, speed up your Android device, and monitor its temperature.
1) Superuser – The first app to install on a rooted Android device
A rooted Android device won’t be as useful if apps don’t have root access. To fix this problem, make sure you install Superuser soon after rooting your device. This will automatically force apps to ask permission to establish root privileges. Once the app has root privileges, it can perform a wider variety of useful tasks than ever before.
There are so many more apps available to rooted Android users than just the ones listed above! To fully experience the wide range of apps that are available, try out One Click Root for yourself today and start using your rooted Android phone in just minutes!
