How to hide my Android WiFi hotspot from being detected? I have a Samsung Galaxy Young phone and a 3G connection. I use my phone as a wireless modem, but I don't want other devices to find my WiFi hotspot when they search for WiFi.
How can I stop other devices from seeing my hotspot?
Don't waste your time trying to hide your hot spot - you can't really.

What you CAN do however is to require a password to allow a connection TO your hot spot.

In some cases, not sure here as I do not have your device, it is possible to lock the hot spot and only allow connections from one (or more, if there are others who also need to connect) specified MAC addresses only.
