Yes. If someone has installed a spy or monitoring application on your phone, they will be able to see all text messages you’ve sent and received. If this is being done without your knowledge, we recommend:
- You talk to the person who’s spying on you (if you know who it is).
- Try to find the app/software on your device and delete it.
- Reset your phone to factory settings (only use as a last resort).
- Get a new cell phone.
