How to attach a USB external hard disk drive (HDD) to a Samsung Galaxy Tab 4 using the LAVA SimulCharge USB TL-002 adapter. The SimulCharge adapter uses USB On-The-Go (OTG) interfacing and lets you charge the tablet and power the hard drive at the same time. This functionality is also available on LAVA's STS-* product line providing multiple USB ports, LAN, PoE.

NOTE: FAT32 file system should be used, as Android does not support NTFS.
