Hello, I need some help. I have the d802 model of the LG G2 and I have a problem: in order to use 4G I have always to go on the phone app and type the code *#*#4636#*#* then a menu opens and I have to go Phone information and then Set preferred network type and finally select LTE/WCDMA/GSM. But he problem is that this setting always reset when I restart the phone or even randomly (It always go back to WCDMA preferred), so I can't use 4G anymore.
Ps: Even while LTE/WCDMA/GSM is selected I'm not able to select 4G at Settings > Tethering & networks > Mobile networks > Network mode, but it still works
Ps 2: I'm using pure stock 4.4.2 KitKat ROM
Ps 3: I did hard reset the device
Ps 4: My mobile service is Claro, from Brazil
