Lumia 1020 high pitch cracking noise when dialing ?

[simi_id]

Hello,

I have a Lumia 1020 and I saw if the master volume is around 25 from a maximum of 30, when I dial a number in dialing pad, there is a cracking sound in bottom speaker.
Is this normal ? I mean other users experience this as well or is a particular issue on my phone ?

Thanks

I haven't heard the crackling sound on my 1020 while dialling. However, since yesterday I do notice a general distortion and static during calls. I am not sure if it's the same thing that you are talking about though.
