6 smartphone spy features that could save your life one day

You probably know that you can use the volume buttons on your smartphone to take pictures. What you probably haven't heard of is that you can do the same with the buttons on your headphones. They should be classic wired headphones with physical buttons, and this only works with iOS.

Some applications allow you to do something similar. You can adjust both video and audio, so the smartphone will notify you if there are any movements or noises near the camera.

There are applications that are installed on the phone and computer that you want to monitor. You can control your desktop remotely or just watch what's going on there. How incredible.

Whether you're doing magic tricks to your 5 year old niece or you're in trouble, you'll be interested in the Wave Control app. It allows you to unlock your device or answer calls without touching your smartphone. Just wave your hand and do the magic. An Android version is also available.

Sometimes you don't want your IP address to be tracked from the websites you visit. Apps like hidemyass will give you a free VPN so you can surf the web and feel more secure. It's like having a mailbox on the Internet - an address that no one can trace. You can even select the country where you want your new IP address to be located. Hide like a real spy.

Just activate the alarm mode on your smartphone with the simple Don't Touch My Phone - Anti Theft Alarm app and don't be afraid to leave it unattended. If someone tries to take your phone and read your messages, the alarm will immediately go off. You can even record your own alert to scare this curious guy.
