People who set up others' phones—used phone resellers, mobile phone store employees, senior digital assistant volunteers—spend an average of 40-60 minutes per case because data migration procedures vary by device model, OS version, and app. In particular, KakaoTalk backup, financial app re-authentication, and OTP transfer can lead to customer data loss if mistakes are made, resulting in claim costs of KRW 50,000-100,000 (approx. $37.50-$75) per case.
A web app that automatically generates a data migration checklist for each device/OS combination and records completion of each step with photos/screenshots to create an audit trail. (1) Enter the source and destination device models to automatically generate a tailored migration procedure, (2) check off each step and attach screenshots to defend against claims, and (3) pop up troubleshooting guides for frequently failing steps (KakaoTalk backup, OTP transfer, etc.).
