My blue one life x2 camera not working right after the update

Whoever owes blu one life x2 cell phone might still remember the system update issue. I have to reset my phone and wiped out all the data. The phone is working but I just found out the weird thing about the camera. When you take the pictures, the light just spread and stretch to long rectangle shape. Hard to explain. But it's fine when you do selffi. Anyone has same issue and how you fix it. Thank you so much. I think it's caused by system update.
