My title pretty much sums it up. Hahaha

Welcome to Android Central! We don't allow discussions on how to spy on others' phones. As for someone else snooping on your phone, how do you know that for sure?

[James Frampton]

it is pretty obvious. I get signed out of my email. all of my files go missing. my screen flashes as I have dev options open. my Bluetooth will come on by itself.

That sounds more like the phone malfunctioning than someone spying on you. Which phone do you have? Does this happen in Safe Mode as well? Why do you have Developer Options on, and what Developer Options have you activated?

Yep having dev options enabled can cause most of those issues, and depending on what you have turned on in dev options can cause even more issues. I stopped using dev options after issues like yours. They were fun to play with short term, but caused too many problems long term.
