Re: [android-developers] Sprint 4G(WIMAX) tcp connection problem
We only see this issue on Boost phones on WIMAX actually. Pure Sprint phones work fine. The minimal required period is a crazy value like 3~5 seconds. Hope this info can help. Our guess is that maybe Boost rents other company's WIMAX network, so they would like to try their best to clean up idle connections. Thanks. Cheers.

Re: [android-developers] Sprint 4G(WIMAX) tcp connection problem
It's galaxy S2. I believe the GCM works on this phone. I am wondering what GCM does to keep his socket alive. It would not seed keep alive packets in short period like several seconds, this would burn out battery very quickly. My guess is that the carrier can recognize the GCM tcp connection and only keep it alive. Cheers.
