In addition to recording their surroundings using their camera, mSpy also lets you listen in on what’s happening via a hidden mic. But seeing and hearing their surroundings is just one part of the story. mSpy is known for on-device monitoring. Once installed, you’ll be able to read their texts, view their emails, see their private social media chats, view their location, see screenshots of their phone in use, find out who they called, and so much more.
