Much of the connectivity foundation is shared: both phones support 5G, Bluetooth 5.3, NFC, USB Type-C, and the same core sensor suite — gyroscope, accelerometer, GPS, and compass. For everyday wireless tasks, either device holds up well. The A36 5G does pull ahead on cellular speeds, however, with a download ceiling of 2,900 Mbits/s versus 2,550 Mbits/s and upload of 1,600 Mbits/s versus 1,280 Mbits/s — a moderate but real advantage in throughput-heavy scenarios on compatible networks.
Two connectivity differences carry more day-to-day weight. First, the A36 5G adds Wi-Fi 6 (802.11ax) support on top of Wi-Fi 4 and 5, whereas the A17 5G tops out at Wi-Fi 5. Wi-Fi 6 delivers better performance in congested environments — think busy offices or apartments with many competing devices — along with improved efficiency and lower latency. Second, the A36 5G supports eSIM alongside physical dual-SIM configurations, offering flexibility for travellers or users who want to switch carriers without swapping physical cards. The A17 5G is physical dual-SIM only. The trade-off is that the A17 5G includes a microSD card slot for expandable storage, which the A36 5G drops entirely — a meaningful consideration for users who rely on cheap external storage rather than managing onboard capacity.
On balance, the Samsung Galaxy A36 5G has the connectivity edge, with Wi-Fi 6, higher cellular speeds, and eSIM flexibility all pointing in its favor. The A17 5G's expandable storage slot is a genuine counterpoint, but it is a narrow advantage that applies mainly to a specific type of user rather than offsetting the A36 5G's broader connectivity gains.
