I did not run any longtime tests (or special tests for modem stability),
but in my normal tests I could not observe this problem.
Neither did I get any reports about this problem from other users.

I remember the problem had something todo/could be influcenced by the
AT_OPSYS command, which can be switched from the Android Settings GUI
[1], if somebody wants to run some tests.

Another quirk which was introduced to better support our modem is a
workaround for the broken AT+VTS command in the firmware.

Best,
  Lukas
