Phone Hacked

There is no one way.  Each exploit has its own set of details.  Some are very good at hiding their existance.  So the best advice is to make an assumption. 

It's pretty unlikely that your phone is hacked if you only downloaded apps from the Apple or Google stores.  If you have only installed apps from those stores you are probably OK.

On the other hand, if there are symptoms, such as lots of ads popping up, unexplained charges on your phone bill or credit card, or a sudden slow down, then you might assume that it has been infected with malware.

Fortunately, most malware won't survive a factory reset.  Follow the procedures for your phone to preserve your data and perform a reset.  Then, you will KNOW that your phone is free of malware (for a while.)

OK, let’s roll….and Hey!...Lets be careful out there.
