I think this may have started since the last system update, but my galaxy SII now auto-connects to any WiFi network in range. This is incredibly frustrating because it drains the battery like crazy. The other night, for instance, I had a fully charged battery before I went to bed (I had the WiFi off), but the next morning the WiFi had turned on automatically and my battery was at around 50%. Very frustrating. I read in another forum post that "forgetting" networks will stop the phone from auto-connecting, but that's not an option for me because the security keys for the networks I use sometimes are long and impossible to remember. How can I STOP the phone from automatically turning on the WiFi?
