I often dealt with things like it more when I used a SIII, S4, and Note 3. Back then, these phones had amazing (well, to me at least) lock screen effects, water for the SIII, light for the S4, and so on. If you used a secure lock, those effects got disabled and it was just bland. So I often just used 'swipe' for unlock at the time. Unfortunately, having discovered that I somehow 'sent' random gibberish to contacts, to having 4 apps open on their own, to hearing my pocket going 'bwop bwop bwop' (back when they used nature touch sounds) as I moved around, I started using more secure lock screens. Today, those iconic effects are no longer done so you don't benefit any way from not using secure lock, visually or otherwise.
Unfortunately, if you use a standard candybar form factor phone today, you can still pocket-interact with music widgets on the lockscreen, pocket-launch camera, or enable torch and drain most of your battery before you catch it.
