Success - Turn 4G off and keep it off!

[tiede]

The best way to turn off 4G witout a restart, and still have it off even after a phone call/txt message involves downloading and app from the PlayStore called "Restart connections"
Then open the shortcut **583385## and select CDMA only mode.
Once you've done that, open the "restart connections" app and it'll cycle through your connections and land you at 3G.
4G will remain off from then on.

NOTES: This process is less succesful the other way around. (it may work 10% of the time, but most likely will fail if you are trying to jump back from 3G to 4GLTE mode).
You may have to open the "Restart Connections" app a couple of times to get it to actually reboot your connections, depending on the 4G state.
If it still can't go through after about 3 or 4 tries, you can manually close the 4G connection using the LTE Functionality Test Shortcut, and then retry restarting all the connections using "Restart Connections"

I suspect some faulty code from Samsung may be why it's required to go through hoops at times to restart all the connections, and requiring an actual reboot to jump back on 4G 90% of the time is only reinforcing that huntch of mine...

I don't care about a reboot, I just want the shortcut I had back on my homescreen that took me directly to the same menu that **583385## takes me to.

Install LauncherPro, and use LP's shortcut maker to find and add the app on your homescreen as a shortcut.
Your default launcher doesn't even have to be LP, it's just that LP's shortcut mini-app picks that hidden menu while Anycut doesn't.

everytime i do **583385## and turn off LTE ( did 2 times) it would not work after that. i could not receive or send calls or messages.

i have to do hard reset and start from scratch.

so i just use anycut

on the phones keypad dial: **583385##
You will then see the option to enable only CDMA.

after doing this it will say the action will take effect after the phones next reboot. Reboot the phone and it will now use 1X forever until you go back in there and turn LTE back on.

To turn 4G back on you are going to want to select Enable Global Mode. This will allow LTE and CDMA. If you select Enable LTE only it will turn on 4G but turn off CDMA meaning no phone calls.

Are you recommending this because 4G drains the battery so fast?

- his is the only reason I wanted a 4g off app. Though as it turns out I have 5 spots in the surrounding cities that actually give me a good 4g signal and I have learned to live without it.

Please forgive my noobness, but isn't 4g super fast? Why would you want to disable it?

Because it kills the battery very fast and at times it can even make your phone overheat, so to save battery ppl only turn it on when its needed and off when its not being used.
