There are a lot of different devices that run Android, with their own hardware configuration. This means sound loops may be handled differently from one device to another. If you hear sounds crackling or skipping periodically, or even if they stop at times, the audio loop correction mode set may not be ideal for your device. Luckily, you can fix these issues by changing the Loop correction mode in the app itself. To do this, open Relax Melodies, select Profile (More if you are on Amazon) and tap the gear icon to open Settings. Tap Loop correction mode and then select one from the available modes. You may have to try several modes before you find the right one for your device. Note that choosing Off will deactivate sound looping.
