I well can navigate my phone except call log, pictures, messages and sound recordings. i have even removed my pattern to see if it could disarm all passwords. Not to know my email and password could as well mean I have a phone that is not mine. It has once happened to me. an apk file was developed by a blog site, 101techstreet.blogspot.com, which I used and it worked but on visiting the site again, the file has been removed in claims that it violates Google's Terms of Service. And i have search and surfed to no avail. Please I will appreciate all possible help.
