I would imagine that it would differ from phone to phone, but probably nothing. If you mean how much does it cost to make a google+ account, that nothing, though you need an iâ¦nvite to the site and a google account. 4 people found this useful.
There is a phone number you can call that will help you determine whether or not your phone is tapped. Call : 202-543-9994. You will hear a long tone , listen carefully to this tone . If it is a long steady monotone then your phone is not tapped.
In a phone, proximity sensor is used to turn off the touch screen, while making a call with phone positioned close to the ear. You can test this by making a call and placing hand/object close to the speaker at the top, screen will turn off. This is done to avoid accidental touch while making a call.
