Before we proceed on the ways on how to detect keylogger on Android, let’s first discuss what keylogger really is.

Generally, a keylogger is an application or a portion of an application that’s designed in recording whatever a target system is keying or typing on their keyboard. This target system might be an Android phone, an iOS device, or even a computer.

Furthermore, an Android keylogger is also defined as a piece of software, which might be installed secretly on a smartphone. This allows you to monitor an Android device remotely, as well as view almost all data stored on it.


Since keyloggers record all keystrokes that are made, looking at the record of the application may show the necessary or private information of a person. This includes text videos, photos, social media activity, browsing history, applications, emails, call logs and text messages.

In order for you to prevent someone from hacking your Android device, you should familiarize yourself with the different signs, as well as the ways of detecting keyloggers on Android phones.

Phone turns on and off suddenly

Is your phone turning on & off so suddenly, and for no ostensible reason? Probably, some code or software like a keylogger has interfered with your phone and has affected its operating system. In case this happens, your smartphone might do some abnormal things, just like turning on & off suddenly.


However, there is no need for you to go crazy with this sign, as some old smartphones do this sometimes. Nonetheless, keep a close eye for some other clues when you see this kind of odd behavior going on.

Receiving strange text messages

Are you getting some strange text messages on your phone? Perhaps ones with a lot of numbers and letters, which look like a code. Perhaps, just a random talk from various unknown numbers – they might be anything.
