I have a picture of a girl drinking tea showing up in my photo gallery that I did not take. I cannot share it in any manner. Third time it's shown up and I delete everytime. I have an S7 edge. Very creepy. Advice? Is my phone hacked? No idea where it comes from. No details when I look at details on the photo, just a time stamp. Why does this keep occurring? I have looked for secret apps and scanned my phone with McAfee. Help!
