Sometimes when downloading sound packs, the download can stop at a specific place or simply at 0%, in this case, one of the following ways can help: 

  1. If sound packs are not downloading, please make sure you have Wi-Fi enabled and enough free disk space on your device (about 20-30 Mb) - this solution must help often.
  2. Try to turn off the app (remove it from the background or stop it via device Settings) and run again.
  3. Try to reconnect to the internet or try another internet provider.
  4. Try to use the Clean Master app to remove the cache.
  5. Try to turn off and then turn on the device.
  6. Try to reinstall the app.
