[Q] what app can do screen off auto turn to 2G,screen on turn back to 4G?

---

I want to save battery life ....

I do not know about the app but there is one problem. Sometimes I download large files and i do not want to keep my screen awake all the time. But if it switches the connection to 2g from 3g (or vica versa) it disconnects for one second and the download fails.. So that could be a problem for downloading large files.

if can set the timer,that problem can fix

Juice defender can do that I think. Haven't tried it myself I don't use that app anymore, but I believe there was an option in it to toggle between 3g and 2g. However, you have to have root access and a kernal/rom that supports it. Stock kernals don't support allowing you to switch between 2g to 3g without doing it manually yourself through the settings, so you probably need to find a custom one that does.

You'll need a mod ROM to get full use of Tasker for battery improvement. Stock ROM doesn't allow 2G/3G switching.

I understand that CM10 allows this.
Someone should confirm, as I've stuck to rooted stock rom in SIII and plan to keep the same on Note II.
