Let’s face it, at home, there might not be a huge risk to leaving your phone unlocked. Yes, a sibling could snoop into your phone and take a look at those risque pictures you have saved or see who you have been texting, but that might not be the absolute worst security breach to deal with. Luckily, Android Lollipop adds a trusted device feature that allows you to automatically disable your lock screen if you are on a trusted wifi network or connected to a trusted Bluetooth device. Fortunately, if you don’t have lollipop, there is still a way to achieve this. If you are feeling adventtorous, you could also use Tasker.
