Chinese phone. JB 4.2.2 and it is rooted. I tried it again, when I press "Sync time" I got response "No root access. Do you want to set up time manually?"

I tried both, GPS - NTP, and GPS is great. As I said, after using it, Igo finds sat's almost instantly.

Before you install STSP, it says that it "prevent phone from sleeping", so the battery will be empty much faster.
