My phone updated this morning, and I now can't disable 4G service. Where I live, I barely get 4G and it kills my battery. I had it disabled before this update. Now, if I try apps like 4G toggler, it doesn't work. If I open 4G toggler, it just takes me to my phone settings which can't be modified. If I try to type in the *#*#4636#*#* as soon as I type in the last *, the rest of the number disappears. Any way around this yet?
