Hi, all.
How get to the Engineering mode, not diagnostic. Not Testing *#*#4636#*#*
I ask about the engineering mode with customizable phone (including sound).
EngineerMode is available at MediaTek phones. The eMax mini contains a Qualcomm processor, no EngineerMode. Theoretically you can change the hardware settings with the QPST Service Programming app.
For those who can interest : in UMI Rome it's not possible to enter in engineering mode dialing strings. You can enter there only through Mobileuncle tools or MTK engineering mode.
Thanks for the code, whether you know it can also check on the display. Samsung has the test code * # 01 # * and there you can see everything to know if the phone does not have any hidden surprises. thanks for the help
