FIXED IT! Okay, not totally. I couldn't get rid of the emergency call button, but by downloading sqllite editor I was able to edit the emergency contact and change the number to NOT 911. I set mine to 12345 so when pressed it just "cannot complete the call as dialed". No more pocket 911 calls. Here's what I did.
Root the phone
Download SQLite Editor (costs money, but you really only need it for 5 minutes, you could always REFUND it when you're done, but $5 is a small price to pay for this fix, and you never know when you might need to edit another database.....)
Open SQLite Editor and navigate to data --> data --> com.android.providers.contacts --> databases -->contacts2.db --> emergency
Select the only entry and click edit (pencil icon)
Change the number to whatever you want. I don't advise an actual working number because then you'll be pocket calling them instead, but whatever floats your boat. Hope this helps!
