Any electronic device that is connected to the internet can be hacked, no matter what. As soon as people get to know this they become really paranoid. Not every person has an important personal or official data on their computers that no one else should get access to. But when it comes to phones, almost everyone has something to keep safe and secure. And most of the Android phones stay connected to the internet at all times. It does not have to be highly skilled hacker who remotely gains access to your phone. It could just be a jealous colleague or your spouse who physically installed a spyware on your phone when you were not around. Thus, you should always be careful about this. There are a few things you can check to know if your Android is hacked. Some of them are mentioned below.
While using a free app you must have seen ads that tell you about other apps or something like that. These ads are said to be pop-ups. If you see them only while using some specific free apps, then there is not a problem. But is they come out of nowhere when you are doing some offline work or so, and then you need to be worried. It means that an adware is installed on your phone. This is not very harmful, but is really annoying. It will often obstruct your work as you might have experienced.
Any type of adware or spyware that could be installed on your phone will obviously sent some data back to its source. Adware will send things like your browsing history and spyware will send records of your calls, messages, location, etc. Sending this data will affect your usage obviously. So, go over to settings and then to data usage on your phone. There you will see how much data is used by which of the apps you have installed. Generally you will see names like Play Store or Twitter on the top, or whichever app you use the most. But if you have a malware on your phone, then there will be an unknown name. You can search that name on the internet to know more.
There are many malware apps that work in the background and also do not use much data. But you can still trace them by monitoring the battery usage. These apps run in the background at all times, even when there is no other app running. This means that they would use more battery than any other app. So, you can check the battery usage entries for this.
