My 1520 make a strange sound from the speaker at any time the keybord appear or dissapear, is that normal? Never had this on lumia 925, 920 or 720... The sound is strange like distorted sound... Any help here?
Are you sure it's not a keyboard "closing" sound?
I was spit-balling. I thought it might have been a new feature on the 1520. I have a 928 and I don't have the sound. Could it be that you're hearing the button push of the back arrow?
I don't close the keyboard by back button instead I touch anywhere above the keyboard and it disappear...
