Alcatel Idol 2 OT-6037Y flash bleed?

Hi, i have Idol 2 and my phone is taking very bad photos when using flashlight. It hase unchangeable battery so i think i cant open its case, or i dont know how.
Flash bleed-passes thru plastic part to camera lense.
Is it fixable?
See some photos taken with flash at night.




sorry for bad english and please admin move this threat to proper subforum...
