I had forgotten my password to login to my Galaxy S8+. Running out of attempts i google unlock fixes for my device. I saw that Samsung has software called find my mobile. Yet I can't seem to enable it on my Galaxy S8+ or my TabS2. Luckily I was able to figure out my Passcode on my last attempt. Is find my mobile by Samsung a feature you turn off or do I need to locate it in a different area from where Samsung says it should be?
