I've tried to search and most posts come up as old. Also some apps might not be legit. What I'm looking for is an app or process to hide pics. Couple of things going on. I use my phone at work to take pics of different things to show coworkers. I also may screenshot silly things or take pics of silly things I see around town. I wouldn't want coworkers to see those. I've also started seeing a younger girl who thinks sharing pics is great. I play along. But still don't want others to accidentally see them. What's the best way to work around this?
