It's difficult to say for sure whether or not the cracked glass screen on your Commando will be covered by warranty. Personally, I would say yes based on my own experience with smartphone repairs, but then again, it would be up to the repair or service center to determine what to do with your phone when you decide to bring it in.

It's not unusual for people to drop their phones nowadays, so just bring it in for repairs and tell them what happened if they ask you to. I'm sure they will know what to do with your phone in order to help you.
