bluetooth error get my crazy

Hello all,

First i want to tell you that my z1C had a very bad month.

i own it for almost 2 years, and it never had water problems, until 2 weeks , i took picture in the pool, then the lcd phone got water in it. 2 weeks in rice bag and the phone work but the lcd still has little "clouds" signs.
i don't know if it worth to be repaired, i afraid about rust.

But it's not my big problem (yep) , i power on the Bluetooth then the phone get crazy with blinking message error "unfortunately the process com.android.bluetooth has stopped".
i really don't want to reset the phone....

i already empty the cach and dalvik cach.
