I'm unable to make calls because of not registered on network problem (my phone is G925I)
When checking *#06#, it gives me my correct IMEI code
But when testing *#0011#, I got IMEI Status: NG
What does NG mean and if it is a problem, how to repair it
if you have also this problem there is a good news for you because you can find your's answer
Imei: NG = The cert file signature has not been written successfully
All team more, please
