Battery Low Android 4.2.1 Cant Upgrade Camera sdcard1 issues

Ive been trying to upgrade the camera app on my phone on and off for about 3 month now. I have a Haipai 9389 with the KING rom.

Problem is i simply CANNOT get video to record to sdcard1 (my external 16gb), nevermind the constant having to copy pics across! I cant believe its such a pita! Since the phone came out with an sdcard0 every darn app seems to decide this has to be the write path.

Im pulling my hair out, ive tried the cwm / dalvik/cache wipe zip install - overwriting the gallery apk file with no luck whatsoever.

If anyone can PLEASE help id really appreciate it..

I have full root access . etc..
