Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
What password, to what account or device that is, do you need to reset?
I may be able to instruct you how to get it reset.
I have no power over your Google account myself.
Has the S7 always belonged to you?
Is the problem, simply put, that you cannot unlock it, log in to it, etc. ?
You can reset the device, but in that case you will be prompted for the original password ***** the Google account of the original owner.
Would that do you any good, do you think?
