Strange issue. Problem with sensors.

I have a problem with my wife's phone.

From the beginning:

- new LCD

- new "big flex"

Problem:

>>The sim card has been inserted:

- sensors do not work (proximity, accelerometer, gyroscope)

>>Sim card removed:

- everything works.

I tried to change the firmware, but it did not help.

Any ideas?

At the weekend I will open the phone. Looking for clues.

Did anyone have a similar problem?

Regards

Lukas
