I bought the Samsung Stratosphere about a week ago. To tell you the truth I am not a big fan so far. It really likes to use wifi, which is fine with me, but I have a lot of problems with things syncing while it is on wifi. We have a wifi network at work and none of my personal accounts(Hotmail, yahoo) will snyc while I am on it. I go to the account and hit refresh and get a server error. I turn off wifi and it syncs right up. I don't have as many problems at home on wifi, but sometime I will have where nothing will snyc(apps or mail) on wifi and I have to restart the phone. Is anyone else experiencing the same issues? Is this just a limitation to the phone on wifi? If I run on 4g, I don't seem to have any issues. I just like the wifi to save data and battery life.
