Something really strange happening to my L920 since I came back from Cambodia. When I switch back my carrier to Maxis upon reaching Malaysia, my phone cannot received call, cannot send SMS and no data connection when on Maxis 3G (H or H+) band. Hmm... strange huh?!...
When I forced the phone to downgrade to Maxis 2G (EDGE) band, all seems to be fine and my phone can call, can send SMS and data connection.
Just to confirm my suspicious above, I go to area which have Maxis 4G (LTE) band, data is not a problem but as soon as I want to make a phone call it will be "Call Dropped" as the phone when you make phone calls at 4G (LTE) area the phone will utilize the 3G band (H). So this confirms that my phone for whatever reason just failed to work on Maxis 3G band!?
At first I suspect is the SIM card, but when I swap the SIM to another phone, no problem at all. I also put in another Maxis SIM card into my L920 the same scenario happens (the only thing I yet to try is to put in another Telco SIM card into my phone which I dun have lol). Then I decided to wipe out my L920 and the same problem still happening zzzz... I even called out Maxis to see anything wrong with my account since I roam in Cambodia with SMART Telco and nothing was found to be unusual... sigh*** I also setup a new APN manually but to no avail with the same issue... sigh***
OK managed to get a DiGi SIM card and worst it that it won't even get connected to DiGi Telco and says no connection. When I put my own Maxis SIM card into a L630, it works flawlessly...
I suspect if my 3G antenna is fried or something? not sure if this is even possible? Anyone had encounter such scenario before? I left it for few days and the issue doesn't seems to go away funny. Seems like I need to visit Nokia Care Centre (parking at AMCORP is superbly expensive!!!)...
i can assure your device's motherboard problem. i did encounter this issue after 2nd week i bought my 920 years ago. and end up sent to NC for warranty replacment. its time to upgarde L930!
