how to close the 4G？！
Yesterday i found that my 822 kept changing from 3G to 4G,or 4G to 3G,which cost power much.
So, how to close it?
does anyone know how?

thanks but my 822 is in the “LTE and CDMA mode”，there is not a“Highest connection speed” selection below....

No CDMA mode?

there are 3 modes, globle mode, LTE and CMDA mode, LTE GSM and UMTS mode, however, my 822 can not work normally in the LTE GSM and UMTS mode.
