10 Codes to Check if a Phone is Hacked (2023)

Smartphones have become integral to our lives. From work to entertainment to communicating with our loved ones, they are a necessary evil to stay connected. Your phone is a prime target for hackers because of the personal information it stores.

Hackers can spy on you and gain access to your most confidential information by tapping your mobile phone; that’s why the security of your cell phone is paramount. Fortunately, you can detect if hackers are targeting your phone.

How To Tell If Your Phone Is Hacked

Have you seen anything suspicious on your phone? Then you need to examine if your phone is hacked. If you notice multiple issues, you should assume your phone has been breached.

Here are points that you should check:

Noticeable Decrease in Battery Life: If you notice that your phone battery dies quickly despite not doing anything out of the ordinary, it could mean that your phone has been hacked. Your phone battery dying even when you are not using it is a definite cause for concern.

Mysterious Pop-Ups: A red flag is constantly seeing strange pop-ups on your phone despite using an adblocker. It indicates malware on your phone, which is trying to steal your information. This pop-up is known as phishing.

Sluggish Performance: Your phone suddenly moving significantly slower or frequently crashing is a sign that someone could be stealing your login credentials. At that time, Malware apps working in the background slow down your phone or cause it to automatically reboot.

High Data Usage: One of the signs that you have malware on your phone is a sudden increase in the amount of data your phone uses. The increase in data usage could be due to apps monitoring your activities and uploading your data to a server.

Outgoing Calls or Texts You Didn’t Send: When hackers tap your phone, they can directly send messages or calls to your contacts. If your loved ones are receiving messages you didn’t send, your phone may be hacked, and your accounts could be compromised.

Unusual Activity on Any Account Linked to Your Mobile Device: Noticing strange activity on any of your accounts could mean that you’re facing a serious issue. The hackers have access to your phone and accounts, meaning you’re in danger of identity theft.

Helpful Codes to Find Out that Your Phone is Hacked

Code *#06# for IMEI Check:

IMEI is an abbreviation that means International Mobile Equipment Identity. It’s a 15-digit number that’s unique to your phone. It doesn’t provide any information about if your phone has been hacked, but that doesn’t mean it’s not useful.

Your IMEI number is a code that helps you to check where your phone is. Essentially, it helps you track your phone. All you need to find your IMEI number is to dial the code *#06#. If your phone’s battery is removable, you may be able to find it there.
