The media outlet TechieRide claims to have found a certification from the Russian body ROSTEST that may concern the hotly-anticipated Samsung Galaxy S10. This report may corroborate earlier leaks that asserted the existence of several variants for this phone. The 'certification' refers to the model number SM-G975F, and 2 different elaborations of the same.
The first of these is the DS SM-G975F, which hints at dual-SIM capabilities for this variant. The other is SM-G975X, which could be a different SKU of some kind. It does somewhat reflect the rumors around the Samsung Galaxy S10 X, a super-spec'd version of the phone that could have as much as 12GB of RAM. Other leaks suggest that the S10 could also have variants with six cameras in total. In addition, the device may come in novel color options compared to the S9 line this time around, such as yellow or green.
Other leaks revolving around the subject of the S10 allege that it could have a ceramic back, a 3D TOF sensor, 5G (albeit for one variant only) and Samsung's new Infinity-O display. However, as its release date is most likely still far in the future, it will be some time before we can test the veracity of these leaks (this new one included).
