[Q] Camera Problem after update - Galaxy S II Q&A, Help & Troubleshooting

Hello masters of XDA
first of all i swear i have tried to look up other threads about my problem and i found some but with no result and why i wanna post a new thread is to explain my problem FULLY since im not sure that i have the exact same problem
Anyhow .. i have been using my I9100 for about 2 years on the same room which is Hyperdroid Andromida 7 which is a Gingerbread 2.3.7 i believe ... and recently i came to the dicision that i should update since new apps no longer work , and here is what i did :
Nandroid Backup along with SD and Internal backup to PC .. then a FULL wipe of the phone and the SD installed .. and after flashing a new kernel i installed the Resurruction Remix Kitkat 5.0 ROM which is 4.4 i believe
everything seemed cool even though i didnt get the chance to check much after i noticed that the camera wasnt working properly .. there was a lot FC and lagging on both FRONT and BACK
so i tried reflashing and redoing the whole wiping of cach and Delvick and such as .. no hope .. tried a new room that is based on stock JB .. i got better results but there was still lagging that i NEVER experianced in my gingerbread room..
so after i gave up hope with that i tried restoring everything as it was using the nandroid restore .. the results were better than the modified Stock JB but still not the same as before this whole thing ..
if anyone can guide me towards ANY kind of a solution i would be gratefull .. even if it means replacing the Cam i would do it even though i hardly think its a hardware issue

Only stock rom.. Or stock based custom rom gives good camera performance..
From gb to kk . is alot of difference.. In terms of stability.. Lol...
Best is to use a stock 4.1.2 custom rom...

thing is i never faced such thing in any other phones that i flash with custom roms .. and as i said even after i did a nandroid restore after this whole thing to the custom gingerbread that i had .. the cam didnt go back to how it used to be and there is still some kind of lagging
My hypothesis is that after the nandroid restore that i did from the which was going from Custom Stock JB to the Custom Stock Gingerbread .. something related to working of the camera has been left and wasnt effected by nandroid restore and appearently can only be changed when i flash a new room
( i hope i make sense )
so what do you think i should do to restore my cam to fully working condition ? or what should i try ?

Wipe data
Wipe cache

Wipe dalvik
Wipe preload(if present)
And the restore ur nandroid backup

Tried clearing camera app data???
Also try some camera mod to see if it helps
If nothing works... flash stock rom via odin

If flashing gb stock rom doesnt works... Try flashing a camera mod or use some other camera app like focal(wont work wid gb) or camera360 to cross verify
