Dutch ROM upgrade Noise problem when dialing

[Guest tim_tim304]

I have upgraded my SPV recently with the new (DUTCH) ROM 4.2.3.3.

This ROM compares to the latest UK version with WMP10.

I have the following issues with it:

1. when dialing a contact, just before I hear the normal operator sound, I hear a loud 'klik'.

2. When using my phone to find a contact, after I left it on my desk for 10 minutes, the SPVC500 reacts very slow.

I tried upgrading the SPV with UK ROM version, but the problem still is there.

Anyone experiencing the same problems?
