How to remove a hacker from your Android phone 

In short, here are the solutions to fix your hacked Android device – solution 5 is 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, they may have left behind some malware to do it for them. Such apps often come with names that include words like “spy,” “monitor,” and other obvious stuff. Here’s how to fix a hacked phone and remove unknown apps by checking for them in real time:

  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 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. Access internal storage (phone or SD).

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

Remove administrator access

Another method to show you how to fix a hacked Android phone is to remove administrator access to your device. 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).

  1. Scroll down to Lock screen and security.

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 free up data usage and solve a problem or two. 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 the 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 the 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 significant 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. So, when asking yourself, “is my phone hacked,” make sure you’ve exhausted all other options before going through with a full reset. Here’s how you’ll carry one out 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. Navigate to General management.

Note: the process can vary 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.
