You know you're gonna have a fun time trying to figure out configuration settings when the user manual for your phone start off with this:

Congratulations on your purchase of the product. Please read the manual carefully to ensure your phone work in best status.

 Security and Notes:

◆     Don’t use it in chemical plant、gas station or near the exploder place.

I have to say, I was really disheartened when I read that. I was really looking forward to using my phone near the exploder place! I guess I'll have to find some equipment that IS safe to use in the exploder place.
