i would recommend you report the issue to ALU, **please**. I’m sure they’ll patch you up 🙂
Being in the system, I can tell you that fault report is really effective to improve a product. The fault is stored in a worldwide database and included in dev plans.
It doesn’t mean the fault is going to be fixed right away, but for sure it will be taken into account for future patches.
For AMR though, I’m pretty sure the problem is already fixed (it was a 3GPP problem)
