It's not that good.. A locked app or photo is visible for 2 sec nd then locked.. i.e. When you lock an app then later you want to open it.. It blinks open for 2 sec. Before you put the password.. If anyone have my phone nd click on my gallery.. It blinks visible then shut down allowing that person to have a quick glance on my privacy. Fix it.. Till then I have to uninstall it.
