Fix Android App Launch Issue

My Android handset suddenly refuses to open its main Phone / Dialer application. Tapping the icon does nothing—no crash report, no error pop-up, it simply never launches. Everything else on the device behaves normally, so I’m convinced it’s a software-level problem rather than hardware. I need someone who knows Android internals, ADB, logcat and common repair utilities who can: • Diagnose why the Phone app will not start, despite showing no explicit error. • Walk me through (or supply) the precise steps or scripts to clear corrupt data, reinstall or replace the APK, or patch any underlying system component that could be blocking it. • Verify the fix by ensuring calls can both be placed and received after the repair. I can provide: Android version details, storage status, recent updates installed, and remote access via screen-share or ADB if required. Acceptance criteria: the Phone application must open normally, stay stable for at least 24 hours of regular use, and be able to dial in/out without glitches. If you’ve handled stubborn “app not opening” cases on Android before, especially for core system apps, I’m ready to get started right away.
