Android UI Demo for Mobile-Service APK

Android Device Service Demo APK – Xiaomi, Vivo & Oppo Description I am looking for an experienced Android developer to create a simple demo/testing APK for a mobile-device software-support business. The application will be used as a UI/workflow demonstration only. It must not perform real FRP bypass, security-lock removal, IMEI modification, or unauthorized device access. Main Requirements The APK should have a professional tool-style interface with: * Xiaomi * Vivo * Oppo * Device/service selection * Device model field * Service selection * Order/request button * Processing animation * Demo result/status * Success/failure status * Order/reference ID * Simple activity/history screen * About/support section Demo Workflow Example: Brand: Xiaomi Model: Redmi Note 13 Service: FRP Reset – Demo User clicks: START DEMO The application shows: Processing request… Then: Demo operation completed successfully. This is only a simulated result. No actual device security mechanism should be modified.
