I used the device locator software from the app store at Google to help locate my phone and now I can't get into it because I locked it with a pin on purpose to see if it would work and when I restarted my Samsung S5 to check on pin, the software would not recognize the pin I chose. Now, I am locked out of my own phone. I used my Samsung tablet S4 to check the locator software and my Samsung S5 phone is not even showing up on the device locator software, but a device that I don't have, which is an S2 is showing up and it will not locate it. It says can't reach it and I don't even own an S2 device. Please help.
