Until now, we saw four versions of the unannounced Samsung SM-G900: SM-G900A (possibly made for AT&T), SM-G900F, SM-G900S and, SM-G900H (Spotted on Postel indonisa website), Now a new SM-G900L appeared on South Korea carrier LG U+ website.
According to http://devpartner.lguplus.co.kr, the Samsung SM-G900L features a 5.1-inch FHD(1920 x 1080) and runs Android 4.4 operating system.
Some rumors suggest the Galaxy S5 sport a QHD (2,560×1,440) 2K display, So do you still think the Samsung SM-G900 is the Samsung Galaxy S5, since the SM-G900L comes with a 5.1-inch FHD(1920 x 1080) display only.
Stay tuned for more information.
