Just as a disease is assumed by looking at some symptoms in the body, it can be assumed that a virus has infected it by looking at some symptoms in the mobile phone. Common symptoms of a virus or malware infection include-
The phone may run out of charge quickly
Battery draining is when the phone’s battery charge ends quickly. If the battery starts draining like this repeatedly then it can be initially assumed that something unwanted has entered the phone. In this case, the charge will end quickly within a few moments of charging the phone. One can also notify with a phone notification.
Unfamiliar app found
Not installed on the phone but such apps are appearing, should be alert quickly. Many times these apps are saved as APK files by going to the phone’s file manager. They gradually start collecting all the personal information. If you see such apps, you should quickly delete them from your phone.
Mobile data will incur additional charges
If for some reason the phone’s data consumption starts to be high, then it should be understood that something undesirable is happening in the phone. Usually a malware or a virus deletes various data of the phone. For this, the amount of mobile internet consumption should be checked from time to time. If it seems to be more than normal, you need to take immediate action.
If the performance of the phone decreases rapidly
As the phone ages, the performance decreases consistently. It’s normal. This can also happen when downloading heavy apps or memory is almost full. But without these reasons, if the performance decreases faster than usual or suddenly the performance drops too much in the new phone then it can be assumed. In that case everything should be checked on the phone.
Changing settings
Sometimes smartphone settings can change by itself. Basically, hackers change the settings of the phone to gain access to important information. If you see something like that, be careful. Also be careful if the phone overheats.
Unnecessary permissions
Be careful if phone apps ask for unnecessary permissions. Because many apps ask for permission out of necessity. They get access to multiple personal information including smartphone camera, location, contact, camera. Because they are used by hackers as their hacking tools.
