[ZTE Axon 7 Questions & Answers] j77moduss:
Phone Signal (2g/3g/4g) + Wifi

1. Intelli3G (X) : Switch to 2g when phone off, turn off data when Wifi connected

2. PNF Root: Changes the pulse interval of the Cellphone and the Wifi

3. Auto Pilot: If phone signal drops bellow a certain value then the phone goes into airplane mode and checks every xminutes for good signal, instead of pinning all the time

4. Gestor de red wifi: Uses gsm towers to localize the wifi hot spots for the network you connect to. If you are in an area where you do not have a network it will disconnect Wifi. Good option if you forget, like me, to turn off the Wifi when I leave home
