Probably not. You can't change it on pretty much every phone I have seen so I don't think so. Sorry!!!
you can't, I'm sorry
Yes you can but it's not as polished as the iPhone's lock or an Android phone's lock screen. And if you meant does this phone have a "lock screen" when you put it to sleep like the iPhone, no it doesn't
Press and hold the lock button
