Vulnerability in Android 5.x Can Cause Anyone to Bypass Lock Screen

On September 15, 2015 The Hacker News reported that a security researcher/hacker  John Gordon has found a bug in Android 5.0 and 5.1 (Build LMY48M) which allows anyone to bypass the password in lock screen of Android devices running Android 5.0 and 5.1 (Build LMY48M). This bug doesn't effect if you have chosen a lock pattern or PIN and also Google have released the patch for the vulnerability .

This is how it works as reported by The Hacker News

• Get the device and open the Emergency dialer screen.
• Type a long string of numbers or special characters in the input field and copy-n-paste a long string continuously till its limit exhausts.
• Now, copy that large string.
• Open up the camera app accessible without a lock.
• Drag the notification bar and push the settings icon, which will show a prompt for the password.
• Now, paste the earlier copied string continuously to the input field of the password, to create an even larger string.
• Come back to camera and divert yourself towards clicking pictures or increasing/decreasing the volume button with simultaneously tapping the password input field containing the large string in multiple places.

Download Free Android App Source Codes

If you are learning Android application development and want to download free source codes then Android Experiments is the best place for you to download source codes of some creative Android apps.
Android Experiments was launched on 12/08/2015 by Google where developers can submit their experimental apps and they can also download and make use of code already submitted.

Initially Android Experiments have 20 experimental apps, this is what they said about the initial 20 apps in their blog.

The 20 initial experiments show a broad range of creative work–from camera experiments to innovative Android Wear apps to hardware hacks to cutting edge OpenGL demos. All are built using platforms such as the Android SDK and NDK, Android Wear, the IOIO board, Cinder, Processing, OpenFrameworks and Unity. Each project creatively examines in small and big ways how we think of the devices we interact with every day.

Different methods to increase internal memory of android device

If you have brought your android phone recently then at some point of time you may want to increase its internal memory even if you have 4GB or more of internal memory.

So there are three type of methods to increase internal memory of your device which are:

1. The first method is you can use Link2sd type of apps which requires your device to be rooted and also you need to partition your SD card. By using this method some part of your SD card will be used as your internal memory to create symbolic links and save app's data, here is a full tutorial on using this method.

2. The second method is you can use Mount2sd app to handle mout2sd script which loads with device boot up. This method requires root access as well as your ROM should have init.d support with partitioned SD card, if you have stock ROM then probably your ROM lacks init.d support but don’t worry there are different methods to enable init.d support on stock ROM, here is a tutorial on using this method.

3. The third method is you can use different scripts to increase your internal memory like cronmod or any others, this method is same as mount2sd but the difference is mout2sd provides the app to handle the script. This method requires root access and init.d support with partitioned SD card, here is a full tutorial.

Here i have not covered other methods like using app2sd type apps because link2sd has almost all the feature of these kind of apps. My personal preference would be the second method mout2sd in which you will get maximum internal memory depending on your SD card's partition.
