sometimes i look at my phone and turn the screen on to find that it's still on 3g when i am at home. once the screen is on, then it turns wifi on. it happens quite a bit actually.
does the phone only switch to wifi when it's not in sleep mode?
update. as it turns out, that place had another wifi called dlink, which is exactly the same as my home wifi. therefore, the phone tried to connect to that, failed cause of password, so it will not connect to my home wifi again. if i change the ssid of my home wifi, it will auto connect
