4G/3G switch app that actually works??

[terryh215]

Does anyone know of a app that I can switch back and forth between 4G and 3G on my Galaxy SIII so it doesn't drain my battery? I use to use Phone Info but it doesn't work anymore since the Jelly Bean update.

Phone info is the only one I know of.

I use to use that but when I updated to Jelly Bean it messed up. Now I can't find it in the Google Play store now

On a similar note, is there any way to force 4g only?

The speed on 1 "bar" of 4g is faster than 3 "bars" of 3g for me.
