Re: how to know my phone has hacked
It's quite difficult to know for sure if your phone has been hacked. Any good spy app will hide deep and even an expert could have problems to detect it.
There are some symptoms that could indicate that your phone has been hacked. The battery is being dried more quickly, your phone gets hot when not in use, it's sending strange texts, etc. But those can be signs of something else as well.
Also, to have an spy app running in your phone someone had to use it for a little time to download the app and set things up.
A factory reset would eliminate that problem. Let us know if you want to go that way and we can help you with the process.
