This might be a stupid question, but if you wanted to just view the lockscreen without unlocking (say to glance at notifications quickly), how would you do that? Use the power button instead of home?
Hmm, yeah. That or press the home button super quick and lift your finger off (on the S6 at least, not sure how it's going to work on the phones that will unlock with the fingerprint reader, but the reader isn't actually a button). Even then, sometimes the S6 reads so fast that just a tap is enough to unlock.
