I, personally, don't use a secure lockscreen on my personal phone but do on my work phone. So it's up to you to decide that haha I've been bashed by many for not using a secure lockscreen, and I get the point, but to me the ease of unlocking faster is better than fiddling with passwords or fingerprints because my phone requires me to swipe the finger to unlock. If my phone had the iPhone-like tap fingerprint reader that the S6 is getting, then I'd probably DO use a secure lockscreen on all my phones.
