Smartphone battery problems
Smartphone temperature is known to rise especially if you play hard games or open a lot of apps at the same time.
Although such practices should not be enough to cause any harm to your smartphone, but it can be a sign that it has been hacked, because most of the malware that gets installed basically runs in the background to steal information, eavesdrop, or record calls.
You should also monitor the applications that you use on a regular basis and how they affect the smartphone battery, especially applications that require Internet connection.
Monitoring your Internet service bills helps you detect spyware. Apps usually use huge amounts of internet data especially if you are not connected to a free wireless network. So you should know roughly how much internet data you use every month.
And if the service bill has increased significantly, you need to know exactly why this happened, as there may be applications that consume internet data in your phone.
Unwanted ads on your smartphone
It is necessary to know what is on your smartphone, especially the applications that run in the background, as the appearance of applications that you did not install previously means that they often contain malware.
These applications can also be used to collect data and broadcast pop-up ads in order to encourage victims to click on the links they contain.
If you find that your smartphone is getting a lot of spam messages or phone calls coming from strange and unfamiliar numbers, then something is wrong.
Likewise, if a family member or friend mentions to you that you are sending them strange text messages or emails, it means that your phone has probably been hacked and that your infected phone is trying to install malware on your friends or family members’ phones.
