Nexus Camera Widget is a free Android personalization app by Ideacabin that allows you to launch your camera quickly from your lock screen. With this widget, you can take pictures and record videos without the need to unlock your phone every time.

This widget emulates the default lock screen camera widget provided by Google to Nexus 4 or Galaxy Nexus, but with added features. You can now start recording videos right away from your lock screen and access Panorama and Photosphere options. Additionally, you can swipe left to view clicked pictures.

It is important to note that you need to tap on the widget to launch the camera. However, the widget launches the camera faster than any other widget in the market or even the stock camera widget. It is also recommended to maintain only one instance of this widget.

While you can swipe left to view clicked pictures, you will not be able to access previously existing pictures on your device. The developers are working on bringing greater functionality to this widget and updates will be frequent. They also welcome feedback and assure users that every feedback will be considered with utmost importance.

Overall, Nexus Camera Widget is a useful tool for those who want to capture moments quickly without the hassle of unlocking their phone.
