Yesterday, we were notified of some issues with the Nexus S 4G’s data radios. Many users at Sprint’s support forums reported a lack of data connectivity and very weak or slow signals. Sprint acknowledged that an anomaly was indeed going on and that they’d be looking into the issue. But just how bad is this issue?

The folks at GizmoFusion decided to put two of Sprint’s 4G phones – the Nexus S 4G and the EVO 4G – side-by-side with 4G enabled. The test is simple – run the SpeedTest.net app. Their findings? The EVO 4G beat the Nexus S 4G by a long shot. In the video, the EVO 4G averaged a downstream speed of 8.4 megabits while the Nexus S 4G could only muster up a measly 2.4 megabits.

GizmoFusion says the 2x-6x difference in speed was consistent throughout several tests. To have two different phones in the same exact coverage area produce two hugely different results is undeniable evidence that something is definitely up with the Nexus S 4G.
