I’ve seen a few interesting videos on YouTube demonstrating using RTL SDR with an OTG adapter on an android phone or tablet getting pretty impressive results. Almost every video is more than 5 years old and the android radio apps they were using don’t appear to be available anymore. SDR++ was used in one of the videos but I couldn’t find it in the Google Play Store. Has anyone played around with this and get it to work properly? Any recommendations for a current available android SDR app that works well would be greatly appreciated
