Hi Andrey,
We have tested the application extensively with full effort across multiple devices, Android versions, and usage scenarios. On our side, the app is functioning smoothly and all implemented features are working as expected.
However, aside from your current device (OnePlus), we have not received any clear reproducible failure from other specific devices with verifiable details. Without at least one confirmed failing device scenario (model + OS + steps + evidence), it becomes technically impossible to debug the issue accurately.
Blinking screen at app start:
As explained earlier, this behavior is caused by the official Android Splash Screen policy on newer Android versions. The system briefly displays the app icon before the custom splash screen, which cannot be fully removed by third-party apps. We have already minimized it by matching background colors. This is standard Android behavior.

Scope — Requested Features Status
Below is the list of functionalities originally requested and their completion status:
Core Fixes
Full synchronization with messenger (media, locations, etc.) — Working
Image sending visibility across platforms — Fixed & Working
Video sending with preview on mobile — Fixed & Working
Audio/voice message recording issues — Fixed & Working
App icon update with new APK — Completed
Requested Upgrades
YouTube / external video link sharing with preview — Implemented
(Additionally, in-chat video playback functionality was integrated, not just thumbnail preview.)
Offline messaging capability — Implemented
Users can record/send messages while offline and they will be delivered once internet is available.
(Extended to all message types: text, voice, images, videos, location, links.)
Push notifications with sound and visual alerts — Implemented
Additional Improvements Delivered
Although not explicitly required, we also implemented several enhancements to improve reliability and user experience:
• Upgraded libraries and introduced future-ready architecture
• Offline cache display so content remains visible on poor or no connection
• Optimized chat loading and message sending performance
• Reduced unnecessary background processing
• Added upload progress indicators for video files
• Updated UI for a more modern and smoother look
• Improved stability to reduce potential crashes on supported environments
Our intention has always been to deliver a fully functional and stable application. At this stage, all requested features and fixes have been implemented and verified on our testing devices.
If you can provide a clearly reproducible issue on a specific device (model, Android version, steps, and preferably a screen recording), we will gladly investigate further. Otherwise, based on all available testing, the project requirements have been fulfilled from our side.
Kind regards,
Dave
