Not a universal solution for Android, but maybe it could lead your thoughts toward something useful. I know that Kodi has a toggle in the settings to stop that from happening. It works by constantly playing an inaudible low-frequency noise. Kodi runs on pretty much any OS, including Android, but since it’s HTPC software, the UX is not optimal on a small touchscreen in my experience, though there are some skins and/or skin settings to optimise the UI for touch-based navigation.
If they don’t, you’ll have to use something like an external RTL-SDR dongle and a USB OTG adapter…
