If you own a Android device and have Android 4.2 (Jelly Bean) or up operating system you should try out the new lock screen widgets. These are not only helpful such as seeing the clock or reading a email without unlocking the phone but also very easy to install.
The installation procedure for Lock Screen widgets is pretty simple.
Put your phone to sleep and then click the power button to light up your lock screen. Next swipe from the left side of the display to the right side. As you do this a secondary screen appears with a big + sign. Tap the + sign to see the available lock screen widgets on your phone. Mind you you will have to open the phone using passcode to access the widgets list. In the widgets list, tap the widget you like and it will be added to your lock screen. You can have upto five lock screen widgets that is one widget per swipable screen.
In case you want to remove the widget tap it, hold it and drag it to the "remove" icon.
This feature has been added by Google in the Jelly Bean os but mind you if you keep your email and calender visible on the lock screen anybody can read the inbox and your contacts.
