After tacking a few pictures, camera in my Meizu MX4 Ubuntu Edition
locks up, i.e. Camera App displays black screen, and if I try to
restart it, it says that this app does not have permission to
access camera. Rebooting the device helps, but only for a few more
snaps.
It seems to happen randomly, sometimes only after a second photo,
and sometimes after 10th or so. It seems to be linked to locking
the device when the camera is on, or maybe switching to other apps,
or a combination of these behaviours, but I'm not sure.
I can reproduce this behaviour with some effort, so I took a look
at dmesg output on the phone, but I'm not sure I see antyhing
incriminating. The log seems to be the same for "healthy" photo and
for "broken" one, both containing a fair number of error messages
[mt-i2c]ERROR,454: id=0,addr: 54, transfer error
[mt-i2c]ERROR,460: I2C_ACKERR
[CAM_CAL] I2C send read address failed!!
[CAM_CAL]I2C read liteon e2prom failed!!
The only thing I have is that I see a lot more mt-i2c errors after
bugged photo:

What other diagnostic can I gather before submitting a bug?

Hi,
are these failed pics by any chance HDR? See

Hi Max,
please subscribe to that bug, even add a comment but certainly mark it
as affecting you as well. It seems to have gone on the back burner
but it is VERY frustrating when it happens.
