Last month, the Wi-Fi Alliance certified a Samsung device with model code SM-E556B/DS. The certifying authority did not disclose the name, but it was revealed that the device is the Galaxy F55 from Samsung. This information was confirmed by Bluetooth SIG, which has certified the SM-E556B_DS and listed it on its website as the Galaxy F55.
The Samsung Galaxy F55, as revealed by the certifying authority, will feature Bluetooth 5.2 connectivity, but other specifications have not been disclosed. Additionally, the SM-C5560 has been listed on the same page as the Galaxy M55, suggesting that the Galaxy F55 and Galaxy M55 may be the same phones intended for different markets.
Rumors about the Galaxy C55 and Galaxy M55 have been circulating, with the SM-C5560 reported to be the Galaxy C55 and the SM-M556E/DS as the Galaxy M55. Another device, the SM-M556B, was spotted on Geekbench last November with the Snapdragon 7 Gen 1 SoC and 8GB of RAM. More information is needed to clarify the details of these phones.
