Ok - here is the status - not quite surprising:

I moved closer to the cell. I got associated to the cell with much better quality. Then the channel switch was initiated by the software - without luck - logs attached:

Any idea why the channel sync fails several times and even the fallback switch to the serving cell at the end?

I have doubts that it is an antenna/RX-issue. If i use the motorola with original firmware, i have no issues and can immediately start a phone-call.

Thank you in advance

Stefan
