LG 4xHD p880 - dialer problem. Possible to smooth miui ? Please answer.

[lg4xhd]

Heloo.

I have question about miui port for this smartphone.

If I go to "dialer settings>>>Caller ID". Application Phone has stopped (crashed). The same situation is on dialer setting>>>call waiting.

In this moment (FC error) My network (GSM) connection has breake and restart.

Log from crash here:

My second question is:

It is possible to optimize this ROM for smoothing ?
I have small free ram on this rom.

It is possible to optimize this rom and repair phone bugs ?

It is ver very nice rom. Best for me (functionality and look).
Best Regards.
