Other point to consider si that when the smartphone has connectivity to WiFi and Cellular, it always uses WiFi. But you can connect to a fix server, considering all 4 factors mentioned above. and Germany, you can track how the Samsung Galaxy S23 performs on our next release of Ookla Market Reports. After promising launches that have seen the Samsung Galaxy S23 models pull ever-so-slightly ahead in the U.S. In the case of 3G, I don't know how you could could establish a connection to the access point like a Gateway GPRS Support Node in UMTS. The Speedtest® Android app can help benchmark your device’s 5G performance. In this case you will have to deal with all the mentioned factors. If it doesn't work you could try a fix server, for example. That would eliminate other the last three factors. Having said that, I'll go with some suggestions:įirst thing I would try, only with a WiFi, is trying to establish a connection to the access point, to por 443. But this last ACK doesn't add significant time to the return of connect because it's just sent by the client. Of course you have to deal with all factors that affect speed.Īnother point to consider is that if you use connect in a TCP socket, you have to understand that there is actually a three-way handshake: client sends a SYNC, server sends SYN/ACK, client sends ACK. I would create a TCP socket and call connect and then determine the time it took since connect was called. You could use InetAddress::isReachable with a timeout various times until you find out the limit timeout. So you might try to establish a TCP connection to some server. However, Java does not provide the means to send an ICMP message. Ping is implemented with ICMP Echo Request. Usually you execute a ping to test reachability and a taste of RTT.
