Is it normal for my Galaxy S5 to always bring up a prompt to "check battery cover" when powering up/rebooting? I recently got a Galaxy S5 and I'm new to the android platform so apologies in advance if this is an obvious question. 

I've noticed that my phone brings up a prompt during startup (after a full poweroff) stating to check my battery cover.  It looks like this: 



Does this mean that the phone senses the cover being loose?  Or is this just a generic message that comes up every time I boot?
Generic message after reboot. It will show everytime and I think you cannot turn it off.
