Android Thoughts: Hidden Messages, Walkie-Talkie Communications, and Video Calling On Your Android Phone With These Apps

"It’s called StegDroid, and it sends a hidden message along with an audio recording to anyone else using the app. It might sound like a harmless voicemail, but contained is a message that is for your eyes only."

"What do you get when you put voicemail, phone calls, and text messages into an Android App blender? You get HeyTell for Android, which will turn your smartphone into a Walkie Talkie!"

Android phones can truly cover all your communication needs. Here are some apps to help you out. First, if you ever have the need to send secure messages and want them to look like they're not of a sensitive nature now you can. StegDroid will let you record an Ogg Vorbis audio file and hide your message inside it. Just have the person on the other end open the Ogg file using StegDroid and they'll be able to decode your message.

Any ex-Nextel people out there? Do you use those 2 or 5 mile range walkie-talkies to stay in touch with family in other vehicles on a long trip? Take a look at HeyTell. It's an app that gives you instant walkie-talkie communications with another HeyTell user.

Last but not least is Tango. Tango is a free video calling app. It's simple to set up and you can even use it for Android to iPhone calling. Oh yeah, it doesn't require WiFi;)
