The Challenge_

The biggest and most complex part of this project was the mobile screen recording of the provided scenario. As the usual duration of a captured video is more than 30 minutes, it also brings challenges into the app. The first challenge was to avoid interruption that may happen during a long test(incoming call, closing application, etc.) The second challenge was tomake video uploading fast and smooth. The third challenge was to record the screen inside and outside of the application.
