My grandfather took his own life last April, and since then me and my family have been trying to get into his tablet for one last piece of his life to keep. It is a pattern lock, and I was wondering if anyone knew tricks to discover the pattern or unlock it without deleting data from the tablet. I am not sure of the exact model, but I will attach photos of the front and back in case that helps anybody. Thank you in advance!
