I opened my new S21 Ultra in a low light room yesterday.
I find a hole on the top of the Phone that i thought was for open the simcard (same place as on my old S9)
I put the tool inside the hole and tryed to open what i thought was the sim card tray.
What is this 2holes on the top for?
How can i test is something now is broken?
I called another phone and put the S21 10cm from a Radio (with the top forward radio) and no music was going from the S21. If i rotate the S21so the botton pointing to the radio, music heard in the other phone.
If i standing near the radio talking in the S21, just a little music heard in the other phone, stop talking and all is quiet.
So i think all is OK.
Hope you understand my English 😉
