Match the symptom to the likely cause instead of repeatedly reinstalling the app.
Black screen with sound
This often points to video decoding or rendering. Restart the stream, rotate the device once, disable battery saver, and update Android system components. On TV devices, try the default display resolution rather than a forced mode.
Picture without sound
Check media volume, Bluetooth output and TV audio settings. Disconnect unused Bluetooth devices and reopen the stream. If only one source has no audio, the issue may be specific to that feed.
Endless loading spinner
Test the internet connection, switch between Wi-Fi and mobile data, and clear the app cache. Verify that date and time are set automatically; incorrect system time can break secure network connections.
Channel unavailable
Live channels can be temporarily offline, region-limited or under maintenance. Test another channel before changing device settings. If all channels fail on one network but work on another, review DNS, router filters or network restrictions.
Avoid destructive troubleshooting too early
Reinstalling is not the first answer for every playback error. Start with stream refresh, network testing, cache clearing and a device restart. A clean reinstall is useful only when the application files themselves appear damaged.
Test one change at a time
Restart, clear cache, switch networks or reinstall as separate tests rather than changing everything together. After each step, reproduce the same symptom and note the result. This identifies the real cause and prevents unnecessary resets of unrelated settings.
Create a compact technical report
Record the device model, Android or Fire OS version, Rongy TV version, network type, affected channel or screen, exact error text and the steps already tried. Mention whether another network or device works. Comparison-based details are far more useful than a general statement that the app is broken.
Frequently asked questions
Why do I hear audio but see a black screen?
The device may be having a video-decoding or rendering problem. Restart, update system components and test default display settings.
What does endless loading usually mean?
It can indicate an unstable connection, unavailable source, stale cache or incorrect device time.
Why does one channel fail while others work?
That usually suggests a source-specific problem rather than a full app failure.
