Xperia L:Error camera not availble

[syte]

After using my  Xperia  c2105  for  three  months  the  camera stopped woking. i  got this  error.... "Unfortunately ,  the  camera has  stopped  working". I  checked for a solution online and  the following  dint work

1.  clearing  data   on  the camera  after opening apps

2. factory resetting the phone

i decided to do a software update  for the  phone  after which i get the following  error "ERRO Camera not  available"

could  anyone  suggest a solution to this error  . Thanks  in advance

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Have you tried to open the camera while the phone is booted into safe mode?

But if you experience the same behaviour in safe mode, I suggest that you visit nearest service center to have your phone examined by a technician. You can contact your local support team for further information about nearest service center and/or how to proceed with this in the best possible way:
