Over the weekend, a series of new Samsung devices labeled SM-G906x received FCC certification. Interestingly, the dimensions listed match the recently released Galaxy S5 flagship.

The SM-G906x variants certified include models for major U.S. carriers, hinting at a Galaxy S5 iteration customized for networks like AT&T, Verizon, and Sprint.
No other details are provided in the filings. But the identical size specs to the Galaxy S5 suggest these mystery SM-G906x devices will fit the same premium form factor.
Rumors indicate the SM-G906x will be the oft-leaked Galaxy S5 Prime/Plus, featuring the Snapdragon 805 processor and QHD display.
Of course, certification documents don’t reveal full specifications. But with dimensions matching the Galaxy S5, the SM-G906x appears destined for a similar premium tier.
Samsung has not officially confirmed the SM-G906x models or their capabilities. But more evidence points to a Galaxy S5 sibling sharing the same foundations but with enhancements under the hood.
The FCC filings represent another puzzle piece as Samsung prepares to expand the Galaxy S5 family. Consumers eager for the highest specs may not have to wait much longer for the Galaxy S5’s successor to arrive.
