I've noticed this too.
My problem with springflash went a little more crazy last night though.
I tried activating it my usual way with the lock switch and it started spazzing out! locking, unlocking, locking, unlocking,locking, unlocking! and no sign of a flash😕
But im also starting to get suspicious of it crashing my phone to a lock state!. What happens is, the screen dims and i'm unable to swipe to unlock or answer any calls/text😕 the only way I had any luck in getting the phone to respond again was by.. believe it or not, activating springflash!
I'm going to uninstall and see how things go for the next few days..
