android device id confusion

Question

If I dial * # * # 8 2 5 5 # * # * ,

Answer 1

I think all the information provided above is well enough to understand the codes.

Yet I think you are still "not able to see the result of the ##8255## dial" (plz excuse if I went wrong somewhere in understanding this)

I assume the reason behind this is one of the latest bug fix against USSD code made in Android. (you may read more about this and check if your device is on the list. its all over the web)

Finally, if you just want to get the android ID straightaway i suggest you to use this app-
