The S4 runs Android 11 with 2GB RAM and 32GB built-in device storage. The manufacturer specifies a rated 1400mAh battery and native support for more than ten document formats. Exact file and app compatibility should be checked before ordering; the manufacturer has not provided a complete format list on its S4 overview.
