None of the MMI codes I punch into my dial pad work. I keep getting the error "connection problems or invalid MMI code"
Code Function
*#0*# Access diagnostics
*#011#Network details and serving cell information
*#0228#Battery status
*#0283#Loopback Test menu
*#0808#USB Setting
*#1234#Software version/ Model details
*#2663#Firmware details(Advanced)
*#7353#Quick test menu
*#9090#Advanced debugging tools
*#9900#SysDump
*#2683662#Service mode(Advanced)
*#34971539#Camera firmware details
I want to be able to utilise all of the above.
Samsung haven't been overly helpful on this matter and they keep fobbing me off to my phone network saying this is an issue on their side, but I disagree. These codes are coded into the device by Samsung, not my phone network.
I have attempted everything online, to no avail
