How can I listen to 27.025 MHz on my Android phone?
Every Android phone has an FM Radio application. Go to Applications list and locate it. Once you locate the app, start it, then use +/- or </> to manually adjust the frequency. In case if there is no such kind of application installed on your phone, visit Play Store to install it.
You can use an app like droid FM Radio Lite: https://play.google.com/store/apps/details?id=com.larphoid.droidradio
