Hi Brian, I found the video is not available. Could you please replace or remove it. Just a kind reminder :)

Actually, there are some spy apps which can track users’ messages, calls, locations without them knowing. Such as mSpy, FlexiSPY, Highster Mobile, etc. But they only said they are used to monitor kids. They are parental control app. While there are definitely some users buy thesse apps to spy other’s cell phone!…

Nice tips! The terrible Internet connection is really annoying! I will try the above tips and see if they works or not. Anyway, thank you Whitson!
