If your EPG program data is no longer showing on your Android device, try selecting a different download setting.
Go to Settings > General > EPG. The default setting is Download if no data on current date.
EPG data updates either by downloading or just be reloading previously downloaded data. Check whether your device notification message says EPG loaded or EPG downloaded.
You can force an EPG download by pressing the Down key instead of OK with the cursor on the Update button.
