1. Pop-up Ads
If you are getting a lot of pop-up ads and a lot of unnecessary apps from third parties, then it is more likely that you have installed a malware/spyware app that displays this type of popup on the screen. In such cases, do not click on that content because it is extremely harmful.
2. Automatically send a call or message to someone
When you check your call log or SMS, you might see phones from people you might not have started and SMS to people you probably don’t know or haven’t started . If so then your phone is most likely hacked.
3. Extremely slow performance
If your phone has been hacked, the system performance may get affected and due to this, the phone may act sluggish and the performance will slow down by a huge margin. And, some apps may open automatically.
4. Excessive data usage
If your phone has been hacked, some spyware uses a high amount of mobile data or Wi-Fi, which you can easily navigate to the phone’s settings. In such a situation, you should check which app is consuming more data in your smartphone and remove it.
5. Fast Battery Drain
While modern-day smartphones can easily last a day most of the time, this can vary depending on the usage. But, if you are experiencing rapid battery drain, then definitely check which app is consuming the most battery and check it.
