New Nokia Secret Code

First, this code will only work for Nokia bluetooth equipped phones.

For the trick, when on standby mode press *#9990# and something will work silently on the background. I believe on Symbian phones it will display a “Bluetooth test mode”. For Series 40 it displays nothing, and will result in a bug – whenever you try to turn of the bluetooth it will refuse to.

We really don’t know it’s purpose but I believe it has something to do with the bluetooth configuration.

Thanks to Francis for the tip

Hope this helps 😉

  1. Tried this with my 6233, and the code seemed to make my bluetooth transmitter always “on” (persistent). Trying to turn it off from the BT menu does not do the trick. You must turn-off the phone, turn it on again and then deactivate BT from the menu. =)
