Is the touch screen on your Android cell phone unresponsive or responding incorrectly? Do some parts of your phones screen respond while other parts do not? When trying to make a selection on your phone does it end up selecting something else instead? Looking for a way to try to fix this and prevent it from happening? Then you have come to the right place. This tutorial describes not only how to test the touch screen on an Android but also what can be done to try and fix it. Before we begin Before we really dive in to testing and troubleshooting your touch screen the first thing that you should do is power cycle your cell phone. Simply powering your phone off, counting to 10, and then turning your phone back on can often solve minor software glitches or software hiccups, especially if you haven’t powered your phone off for a while. If power cycling your phone does the trick then enjoy your working cell phone; if your phone continues to have problems then we are going to want to...

1)  Understand how mobile devices are used Companies must recognize that mobile devices represent a highly valued, real time, ‘always on’ means of connecting. Understanding how devices are being used and what data they can access are the fundamental first steps to improving mobile security. This helps to avoid over-securing devices or applying the same controls for a mobile device as you would for a laptop. 2)  Deepen your knowledge of mobile Embracing the opportunities of mobile simply requires knowledge and small changes rather than trans-formative innovation. Deepening your understanding of the benefits mobile has to offer stands to benefit your business. 3)  Exploit key features to the full Being aware of every aspect of mobile technology allows companies to exploit relevant features, such as the location function.  You can put limits on what people can access outside of the office via the location settings on your employee’s devices. You wouldn't permit p...

An application normally needs permission and should alert user that it needs permission to make phone call, when it is being installed. Researchers at Security firm CureSec has discovered a security flaw in the Android system that allows malicious applications to initiate unauthorized phone calls.   By exploiting this vulnerability, malicious apps can make phone calls to premium-rated numbers and terminate any outgoing calls.  It is also capable of sending Unstructured Supplementary Service Data (USSD) codes that can be used for enabling call forwarding, blocking your sim cards and so on. The security bug appears to be introduced in Android Jelly bean 4.1.1  and it exits in all latest versions through Android Kitkat 4.4.2. CureSec has also released a source code and proof-of-concept application to demonstrate the existence of vulnerability

Turn Android Emulator into a Pwnage Weapon Today, we’re going to look at a scenario where the Android Emulator can be re-purposed as an exploitation tool. Specifically, we will look at attacks that involve cloning an application and user data from a stolen Android phone onto a computer running the Android emulator. An attacker that does this will be able to use the application as if they were the user. They would also be able to return the phone to the user before the target becomes aware of the compromise. A natural defense to this sort of attack would be to have the application verify what device is running it before giving the user access. The application would only be allowed to run on a device registered with the user’s account. A natural defense against this kind of attack would be to have the application verify the device and to run only on a device registered with the user’s account. We will demonstrate a new tool that repurposes the Android emulator to give...

There are multiple versions of Android available in the market today, each with slight differences. See here, how they differ and why it should matter to you. At last count, over 7,00,000 Android devices were being activated everyday according to Andy Rubin, senior vice president of mobile at Google. Late last year, Gartner estimated that Android held 52.5% of the global smartphone market, significantly higher than the nearest competitors Symbian (16.9%) and iOS (15%). There are a couple of big reasons why Android is leading the charge. The wide choice of hardware at all price points, the number of apps and constant development make sure it stays at the top of its game. These are the current versions of Android you'll get if you buy a device today.   Custom Firmware   Should You Install It?   This is debatable. On one hand, many will be satisfied with using launchers to customise their device. Using a launcher (like Go Launcher) can completely change the look of the p...

Why Windows Phone is better than Android ?  Market share of    Android  phone is increasing at a rapid rate but there are some bottlenecks where Android lags behind as compared with    Windows Phone 7 Series  .  Having worked on these phones and having a strict watch at internet, i found Windows Phone 7 a  great  mobile platform.  Regardless of the numbers, WP7 is one of the favorite mobile platforms, outshining Android in almost every aspect. Don’t believe me? Well, allow me to try and change your mind. Have a look at some reasons why Windows Phone 7 is better than Android . Streamlined User Interface Android’s are different depending on the SKU of the handset. In other words, the UI you’ll be dealing with when using, say, a Motorola handset, will be radically different than one from Samsung or HTC . The ambiguity can be disconcerting. With WP7, you know what kind of interface you’re going to be working with...

RLP The Radio Link Protocol (RLP) is used to transmit data over the GSM PLMN. RLP  covers the functionality of Layer 2 of the ISO OSI Reference Model. It  has been tailored to the needs of digital radio transmissions and provides  an OSI data link service. It also spans from the MS (Mobile Station) to the  interworking function, which is located at the nearest MSC (Mobile  Switching Center) or even further. There are currently three versions of RLP: Version 0 is a Single-link basic version, Version 1 is a Single-Link extended version, And Version 2 is a Multi-link version. RLP frames are fixed in length. The frame can either be 240 or 576 bits.  The frame consists of a header, information field, and an FCS field. The format of the 240-bit frame is:   _____________________________________   | Header  |  Information    | FCS    |   |---------|-----------------|--------|   | 16 bit ...

Here is the second post of the series GPRS guide. The LLC (Logical Link Controller) defines the logical link control later protocol to be used for (packet) data transfer between the MS (Mobile Station) and a serving GPRS support node (SGSN). LLC goes from the MS to the SGSN and is intended to be used for both acknowledged and unacknowledged data transfers. LLC's defined frame formats are based on the ones defined for LAPD and RLP.Although, there are major differences between other protocols and LLC, in particular to frame delimitation methods and transparency mechanisms. These differences are necessary for independence from the radio path. Two methods of operation are supported by LLC. These are: - Unacknowledged peer-to-peer operation - Acknowledged peer-to-peer operation All LLC layer peer-to-peer exchanges are in frames of the following format:                    1 byte    ...
