Using biometric features and options in my Galaxy S5
I am just new here and just recently bought Galaxy S5. I am thinking of embedding a useful software with this phone that will require to use my finger print before it unlock. Can you help me with this? Can you provide me what are the best software that can be downloaded from the internet which is much better and with extensible features? Can you provide me instructions on how to add fingerprint in it so that my children can access it also? Can you provide me instructions on how to install it?
