One of the first signs of a hacked smartphone is unusual behaviour. If your smartphone starts opening random apps or showing notifications, or if you notice apps you haven’t installed, your device may be at risk. 

Although some apps may install automatically after system updates, it is always wise to verify the authenticity of the apps through the Google Play Store or Apple App Store.

Unexpected rapid battery drain can also be a sign of a security breach. If your phone’s battery drains faster than usual, it’s important to investigate further.

6. Unexplained Pop-Ups or Ads

Have you ever been bombarded with unexpected pop-ups and ads while innocently browsing your smartphone? If those unwanted intrusions start to feel like those party bumps that just won’t go away, it could be a sign that your phone has been hacked. 

Hackers often use these pop-ups and ads to add malware to your device or trick you into clicking on malicious links. 

So if your smartphone is starting to look like a virtual carnival of unwanted distractions, it might be time to have a look at it…
