1. Implement biometric security settings where user can choose a timer, while user will keep app in background for a specific amount of time, app will see if there is any time setup for time out. If it’s set, app will take user to an authentication lock screen where user can use his fingerprint for biometric authentication to unlock the app and resume using it.2. Saving PDF file for user’s manual in phone storage only once to save storage space and opening PDF file using fileviewer.3. Created UI for an Account settings screen based on mock provided by Design team.4. Created service history report with UIs screens and send data to server using POST requests to API.5.
