Is anyone having camera issues with their BB Q5?

Hi all
I love the blackberry Q5 , and appreciate the bb10 OS. Got bored of IOS and don't like the android phones...

I was happy with it until the camera stopped working three days ago.

I blocked all third party apps, drained the battery, security wiped twice, shut down and restarted the phone dozens of times, downloaded two camera apps,wiped the sd card... But none of this worked.

I still get the can't change flash mode message or can't access then camera one.

Odd thing, I tried snapchat and would get then front camera working.
The handset is no longer under warranty .

I'm wondering why BlackBerry is ignoring the issue, noticed many similar problems with loads of other users that had even changed the camera module.
Any suggestions? I'm worried to change for other Q5 or Q10 as the malfunction seems quite recurrent...

Help anyone?
Thanks!

When you say you changed the camera module you mean you physically had to change the camera out of the phone? I honestly havent seen that many issues like you describe which is why BB is "ignoring" the issue as you put it?
