Chances are that if you have a smartphone or a tablet, there's stuff on it that you wouldn't like every single person around you to have access to - text messages, images, video, apps, you name it. Sure, you can hide your private images
or lock down certain apps using software made for that purpose, but such a solution isn't always enough to keep prying eyes away. What if you want to see who has been secretly messing with your Android device without telling you? Well, in that case, there's a few apps that can come in handy. These three Android applications will let you know when your smartphone or tablet is being used and will help you catch the culprit red-handed. Check them out below!
Anti Theft Alarm is a simple security app we'd recommend using as long as you're near your smartphone or tablet - near enough to hear the siren that will go off the very instant your device is picked up. Here's how to use it:
Anti Theft Alarm
Anti Theft Alarm
Get Anti Theft Alarm from the Google Play store. The application is free, without any functionality limitations, and supported by advertisements.
Launch the app and adjust its settings to your needs. Make sure you set the sensitivity threshold to a usable level - sensitivity may vary between devices so give it a test prior to using the application.
Choose a PIN or pattern that will stop the alarm once it is triggered. If none is specified, the alarm can be turned off with the press of a button.
We'd also recommend setting a siren delay after the alarm is triggered. That gives you a few seconds to input the PIN or password without sounding off the alarm.
Press "Activate Alarm" and leave your Android smartphone or tablet on a surface where it won't be affected by any vibrations. Sooner or later, the culprit will trigger the alarm and have no way of stopping it.
This app does not lock your device in any way. Instead, it monitors the user's activity and logs everything they type (except passwords). Clip Ninja is meant to be an advanced clipboard manager and not a spy application, but it will probably do just fine for figuring out what a smartphone or tablet has been used for without its owner's knowledge. Here's what you need to know about the app:
Clipboard Ninja logs everything you type except passwords.
A logged string of text is timestamped so you know exactly when it was typed.
You can filter logged text by application. For example, you can view only Google searches, only IMs sent through a given client, or only the outgoing text messages even if they have been deleted from your outbox.
The database of logged text can be protected with a pattern so that prying eyes can't see it.
This app will take a photo of whoever turns on the screen on your Android smartphone or tablet (assuming it has a front-facing camera, of course). Photos will also be captured each time someone enters a wrong lock screen password or pattern, thus exposing the identity of the one who stole your device, or was just going through your stuff. But that's not all GotYa! can do:
GotYa! can send the location of your device to your email address, along with the photo of whoever tried to use it.
You can trigger certain actions by sending a specific text message to your missing smartphone.
Captured photos are stored on the device inside a folder that isn't so easy to find. However, you can easily view them from the app itself, along with the time when they were taken.
You can prevent others from changing the app's settings with a password. You can also pick the events, which trigger the front-facing camera to capture a photo.
