A phone with the model number SM-A107F has allegedly gone through certification at the US' FCC. As this number is close to that of the Samsung Galaxy A10, it appears that the device in question is a new variant of the same. Unlike the supposed original, the SM-A107F appears to have a fingerprint reader, as well as a 3900mAh battery.
