i am not able to use wifi hotspot in my lg g4 phone its an AT&T mobile, its showing as turning on and i am getting a pop up window as to enable the hotspot but i am not able to find any icon on phone and when i go back from hotspot window its showing as turn off mode for wifi hotspot please help me to resolve the same.
I assume it's a unlocked mobile from AT&T so that won't be an issue.. I wonder if this is the first time use with a Optus sim (again assuming you can make and receive calls) you may need to double check the APN settings and/or power cycle (as in turn off ect) the phone to get the carrier settings to stick?
Its an unlocked phone, i am using DU sim card of UAE network, everthing is working well and good but when i try to turn on wifi hotspot its turning on but not able to find any wifi clients moreover when i try to turn on bluetooth thettering i am getting an error as "unfortunately, the process com.android.settings has stopped.
So are you even connected to the Optus network or in AU? Maybe the sim/DU carrier settings don't allow tethering? Might be best to pop over to the DU community forum? http://www.du.ae/ourcommunity
I am also having the same problem in UAE. I have LG G4 H810(AT&T) using with Du Sim in UAE. Everything seems working fine except Mobile Hotspot. Showing Error : "Authentication was unsuccessful. - There is a temporary network problem that prevents the enablement of the mobile hotspot function. Please retry later".
