Hey folks, got a odd issue here with a Samsung Rugby phone. We have deployed 3 rugby smart phones to our techs in the field since they seem to be pretty bullet proof devices. My issue is that when connecting the phone to our exchange server all work fine. The issue is that after a few days the email seems to come in and go out at its own leisure causing large time periods of email to be delayed arriving to the device. All setting are set to push mail and it seems to work just fine over the WiFi (as soon as the devices connects to WiFi all email functions fine) and will work intermittently over the 4G connection. We have two other Rugby Smarts set up the exact same way and neither of these other two have this issue. I have updated the phone to the latest OTA update as well. I also use my own Android (EVO 4G LTE) to get exchange mail and it functions fine as well. Anybody else seeing this same issue?
