Yes, you can. There are more than 7,000 native apps on Google Play that you can download directly to Cosmos 4K SE. For apps not available on Google Play, download the APK file and install them from a USB drive. Make sure the File Explorer app is installed on Cosmos 4K SENebula X1/Nebula X1 Pro so your USB drive is recognized.

If the above solutions cannot solve your issue, please contact Nebula Customer Support at support@seenebula.com for further assistance.
