S-Finder is a production Android

S-Finder is a production Android application for mobile phone repair technicians and engineers. I contributed to the development of new features and improvements, including in-app PDF schematic viewing, messaging with seen/unseen status, paginated chat, push notifications, product listings, UI improvements, Android API upgrades, and bug fixes. The app provides access to circuit diagrams, PCB layouts, repair resources, and services for the mobile repair community.
