The update on July 15th has stopped everything from working, I can't connect to WiFi, my other devices connect fine to my WiFi service, all emails and apps now say can't connect to server, my battery life is horrible, completely dies within 2 hours with 100% charge. Is anyone else having this issue, or know how to fix it. I've had trouble with the galaxy from the first day and I'm thinking maybe another brand would be better after this.
