A phone tapped with a keylogger is a bomb waiting to go off since the keylogger secretly records (and emails) every username and password you type in. Keyloggers aren’t foolproof though. There are a few signs that may give clues that it isn’t just your eyes seeing the screen.


1.) Unexplained Data Spikes – Are there any unusual spikes in the size of data being stored on the device? A lot of spyware programs pack data under the hood when you’re not looking so it can be sent out later in bulk. Efficient spy payload you might call it. My Data Manager is good at monitoring this but the best spyware apps will evade detection since the footprint is becoming ever
smaller and the size of devices ever bigger.

2.) Unusual Phone Activity – Things like turning itself off or your lock the screen suddenly flashes on when you’re not using it.

3.) Line Noise – If you’re in the Philippines and making calls, line stability is often terrible in provincial areas like Davao or Dumaguete. That means tons of noise. If you’re in a first-world nation, a constant stream of ‘clicks’ and ‘beeps’
can signal that someone, somewhere, is listening.

4.) Encrypted Emails – This can happen with poorly designed spyware, where you receive odd messages that make no sense and are filled with strange symbols. Spy applications are known to be buggy little critters and not even keyloggers used by the FBI to capture keystrokes of mafia members are perfect.

5.) Odd Files in Directories – It’s often easy to see spyware’s been installed on your device by just looking into a few subdirectories on your Android or iPhone. Often I find if I do a Google search for the name of the file, someone somewhere has likewise found this exact same file. Better still is that they’ve opened a forum thread asking for help. Most of the time the file turns out to be
quite old. This saves me the trouble of using expensive forensic software like

Paraben’s Device Seizure or UFED Physical Analyzer
