Z1 compact strange swish sound

[razvan]

Hello,

I bought one Z1 Compact for my wife in December 2014

It's a great phone except one little annoying sound issue which seems i cannot solve it

I noticed from the begginig that from time to time i hear a strange swish sound like when you try to find a radio station and there is no signal at all

This happenes when audio is not used. Most frequest is when using Facebook app during scroll amond videos (videos are not played !!!!)

I tried system repair but nothing changed

Phone has last firmware update 14.4.A.0.157

Has anyone have the same issue? Is it a firmware bug or hardware? Should i send to service center?

Regards,

Razvan

In that case I would advice you to send your phone in to an authorized service center for further investigation. For more information contact your local support.
