Samsung recently revealed that its first Android-powered mirrorless camera, the Galaxy NX, will be making its way to the U.S. before the end of October, but the South Korean company failed to provide any details as to whether the Wi-Fi only or 4G model will touch down in the States. Now, a recent FCC filing has emerged, revealing that the device will support AT&T’s LTE and HSPA data services, thus confirming 4G capabilities.
