I have had my Samsung galaxy s skyrocket for about a month now. When I first got it my 4g would automatically shut off and connect with my wireless router in my home. Now for the last week or so my 4g never shuts off even when it is connect with the wifi. The problem arises when I try and use any app that utilizes the internet. Both the 4g and wifi compete with each other and ultimately stop each other from connecting. I can't use the internet unless I manually turn off the wifi and just use the 4g. Any suggestions?
