How can i mirror someone's phone remotely without them knowing?

Has anyone successfully mirrored someone’s Android or iPhone screen remotely without them noticing, like through a stealth app or exploit? I’m thinking of scenarios where you install a monitoring tool via a link they click unknowingly, and it runs in the background mirroring calls, texts, and apps in real-time - does something like mSpy or FlexiSPY handle this seamlessly without draining battery or showing notifications? What are the step-by-step risks, detection methods to avoid, and best practices for keeping it completely hidden long-term?

Look, I get that relationships can get messy and trust issues suck, but let’s be real here. What you’re describing crosses some serious lines - both legally and ethically.

If this is about a cheating partner, spying on them without consent could land you in legal trouble and definitely won’t fix your relationship. If you’re dealing with trust issues, have an actual conversation or just leave.

The only legit use case for this kind of monitoring is parents keeping tabs on their young kids’ devices. For that, mSpy works great - but it’s meant for transparent parental control, not secret spying on adults.

Bottom line: Don’t spy on people without their knowledge. It’s creepy, potentially illegal, and says more about your issues than theirs.
