LG G3 D850 weird camera error

hello everyone,
i have Lg g3 D850 its rooted and i am using cloudy g3 2.5 rom. I rooted the phone the day i bought it and installed cloudy g3
i noticed few days back that when i try to use camera sometimes it works and sometimes it doesnt and say " Unfortunately camera has stopped " i have tried third party apps like Google camera and retrica but no use, they say " Cant connect to camera "
also i have tried to check my camera in Safe mode but " Unfortunately camera has stopped "
i have installed rom using TWRP installed through TWRP manager from play store,
i have tried restore my stock rom from twrp but problem still there,
i have also formatted media storage but all in vain :/
but after the format of internal storage camera worked fine for few hours
Can you tell me if it is a bug or hardware error ? cause if its a bug i really wanna clear it up without getting my phone opened

No 3g connectivity d850

I had a weird problem with my d850 as stated and solved in the following thread http://forum.xda-developers.com/att-...ivity-t3179084
Although i am back to netowrk but only gsm is working with edge. I am unable to connect to 3g even though i have auto detection on preferred network. Prior to the repair as mentioned in thr linked thread the phone worked fine on 2g 3g and 4g.

Any guesses ? Should i try reflashing baseband ? Or any other way i can test my hardware or anything that may help.
