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 both the cases, your phone is held near some object (like your ear or the wall of your pocket). In such cases, the proximity will generate a message to your phones processor telling it to switch off your screen. Android and IOS have an API for proximity sensor. So, you can also use it in your custom program. May be say a flash light that switches of if you put your phone in the pocket.
