I have a problem with my Umidigi C Note. When I insert a SIM-Card that is locked with a PIN, I can enter the PIN-Code but I can't confirm it. The button to confirm the entered PIN is missing. I tried it with several SIM-Card and I can't unlock a single one of them. I can only use a SIM-Card when I remove the SIM PIN before. Does anyone else have this problem or can show me a way to unlock the SIM-Card?
Hi,
We are sorry for your inconvenience. It's a known bug and will be fixed in the next update in a few days. Until that, I suggest you to put your SIM card into another phone, and remove the pin-lock protection.
Thank you for your understanding.
