I am an experienced React Native developer with over 5 years of hands-on expertise in building and debugging production-ready mobile applications for both Android and iOS. I have strong experience dealing with device-specific issues, especially Samsung devices, where behavior can differ from emulators or other phones. I understand your issue where calendar events work correctly on simulators but cannot be modified or deleted on a real Samsung Galaxy S25, which typically points to permission handling, gesture conflicts, date parsing, or OEM-specific optimizations. I can quickly reproduce the issue on a physical Samsung device, identify the root cause, and implement a clean, reliable fix without affecting existing functionality. I focus on fast turnaround, clear communication, and minimal disruption to your codebase. I have fixed many similar real-device-only bugs in calendar, scheduling, and event-based apps, and I am confident I can resolve this issue efficiently and get your app working perfectly on all supported devices.

Hello, client I can fix this issue quickly. Since the app works on simulators but not on your Samsung Galaxy S25, the problem is most likely related to device-specific behavior, such as Android version differences, touch handling, or compatibility with the calendar library on Samsung devices. I will debug directly on an S25, reproduce the bug, and find the exact cause. After identifying the issue, I will apply a clean fix, test it on the S25, and ensure the calendar events can be modified and deleted without any problems. I will also verify the same behavior across other real Android devices to avoid future issues. Thanks, Denis

I reviewed both videos (simulator vs physical device). This behavior typically indicates a platform-level interaction issue rather than a logic bug. Possible causes include: - Touch/gesture events being intercepted on real devices due to view layering, zIndex, or pointer events. - Android-specific modal or overlay rendering issues where the popup is mounted but hidden behind other components. - Gesture handler or pressable configuration differences between emulator and physical hardware. - ScrollView or calendar container swallowing touch events on real devices. - Press vs long-press behavior inconsistencies that are tolerated by simulators but not by actual devices. - State update timing differences on physical devices are causing the pop-up trigger to fail silently. My focus will be on resolving the root interaction issue without introducing breaking UI or logic changes, ensuring the edit/duplicate/delete pop-up behaves consistently across emulator and physical devices.
