I have just arrived in the UK for 6 weeks with my lovely Samsung SII (Sprint). I have noticed an unknown icon in the notification bar - it's a circle with a line through it, and when I pull the notification bar down, I see "searching for service". This is towards the top of the screen, but the actual circle with the line through it does not show up when I pull the notification bar, it still stays at the top on the right. As a result, my battery has gone from 100% to 75% in FIFTEEN minutes - obviously whatever it's doing is totally draining the battery. I have disabled the 3g Data box under MOBILE NETWORKS (network settings) - that doesn't do anything. I tried changing from sprint to automatic back to sprint (in roaming mode) - that does nothing (icon still there). The only time it will disappear is if I put on airplane mode - then it goes away but then I can't use wifi to send and receive emails - so that defeats the purpose. I have attached screenshots of both screens. Anybody know what this icon is? Anyone know how I can stop my phone from constantly searching for service while I'm in the UK, without putting it into airplane mode? THANK YOU
