When the internet is changed from Wifi to no Wifi, it always takes a long time to switch back to 3g internet. If I restart the phone, the 3g internet can work properly. Is it a known issue or is it because of some settings? Please advise. Thanks in advance. Background information: I don't know if it is related or not. I am using "APNdroid" to control the on/off of 3G internet and "WeFi Connect" to control on/off of Wifi internet. I didn't do much on the setting of the phone, 3G internet and Wifi internet just set to be "on" by default.
