How to remove a hacker from your Android phone 

In short, here are the solutions to fix your hacked Android device – Solution 5 being optional and only to be taken in the most extreme cases:

Solution 1. Delete suspicious apps

Solution 2. Trash fishy files 

Solution 3. Remove administrator access

Solution 4. Clear your device’s cache

Solution 5. (Optional) Carry out a factory reset 

Delete suspicious apps

A hacker is unlikely to be monitoring your phone live. However, he or she may have left behind some malware to do it for them. Such apps often come with names that include the words “spy,” “monitor,” and other obvious stuff. Here’s how you can check for them:

  1. Go to Settings (by swiping down on the main screen and tapping the appropriate button).

Don’t know whether the app you found is suspicious or not? Google the name! If it’s really an incompetently-named spy app, just uninstall it. 

Trash fishy files 

An alternative is to go through your file sections and directories to look for something suspicious. Here’s how it’s done: 

  1. Find My Files or an equivalent app on your device.

  1. Choose Android.

Again, if you notice anything suspicious, Google the name and delete any offending portfolios and files. 

Remove administrator access

You can also check what apps have administrator access to your phone – there shouldn’t be many. 

  1. Go to Settings (probably via the main screen swipe-down menu).

With administrator access removed from suspicious apps, they can do a lot less damage. At the same time, you might have found some suspicious apps – time to delete them!

Clear your device’s cache

Who knows what hacker horrors – or annoying ads – might lurk in your device’s cache? Wiping them out could solve a problem or two for you. Here’s how the process goes:

  1. Turn off your phone. 
  2. With your phone turned off, hold the Power button and Volume up (though depending on the model, you might need to use the Volume down or Volume up + Home) button to engage Recovery mode.
  3. If the Google logo or Android mascot appears, wait for the No Command message to show up and then hold the Power button and press Volume up once.
  4. Using the Volume controls, navigate to the recovery mode menu and find Wipe cache partition. Select it by using the Power button and confirm that you want to wipe it.
  5. Restart your phone! 

This is a harmless procedure, and it might help. On older phones, it might even clear up some important space! 

Carry out a factory reset

The nuclear option in the “how to fix a hacked Android phone” repertoire is the factory reset, which will wipe your phone, restoring it to the settings it had when it was new. This is not the first step to take, as it deletes everything you have on the phone. Only do this if you believe that the other methods didn’t work. Here’s how you do a factory reset on Android:

  1. Make sure the phone is well-charged or hooked to the charger.
  2. Enter the Settings menu. You can often do this by swiping down on the main screen and selecting the appropriate icon.

  1. Tap Reset.

Note: the process can be a bit different depending on your phone manufacturer. If you can’t follow the steps outlined here, research your phone model!

Your phone’s operating system will now be as good as new! It’s a shame it doesn’t physically renew your phone at the same time…
