GSDer - it's flipping almost instantaneously. When I "connect" to my Wi-Fi, it stays for a few and then as soon as I use my message, email, facebook, etc., it flips over to 4G. My husband's notebook uses our home Wi-Fi connection and he's not having a problem with that OR his S3 either. My phone did an update on Monday (? I think it was) of this week and since then, I've noticed some screwy things going on; i.e., it downloaded a couple of apps I've never heard of, Flip Board, etc., and those I can't uninstall. I'm wondering now if this is related to that. I'm planning on going to my local Verizon store tomorrow when they open and have a tech look at it/explain to me what is happening. Thanks for the suggestions, I appreciate it.
