I also have this bug on MX4 with OTA13. However, I must notice that I2C_ACKERR errors also present in "good" case for me during the taking of photo. The difference between good and bad cases are that these errors appear in large quantity after the photo is taken.
I also would like to point out copious errors "inv_mpu: error in header parsing=8d00" (which could be seen in the original syslog for this bug), which also happen for me. They appear as a nearly endless spam in log when I try to focus camera on something, it seems. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to camera-app in Ubuntu. https://bugs.launchpad.net/bugs/1537774 Title: Viewfinder frozen and all buttons disabled after taking HDR picture Status in Canonical System Image: Confirmed Status in camera-app package in Ubuntu: Confirmed Bug description: Reported by royden in https://bugs.launchpad.net/ubuntu/+source /camera-app/+bug/1475895/comments/6 "Testing the fix released for Bug #1519766 (and likely #1478693) I can reliably freeze the camera-app (v. 3.0.0.616) on rc-proposed Arale r227 by taking HDR images. Freeze happens around the 3rd or 4th shot of the same subject as reported in Bug #1519766. HDR shots of shaded lamp in semi-dark room (taking up 3/4 of view) trigger freeze on 4/5th shot. HDR shots of lamp on small table at distance in semi-dark room do not reliably trigger freeze. Normal shots do not trigger freeze, with or without zoom AFAIKS. Freeze comprises either the viewfinder holding the image of the attempted capture and app being no longer responsive and needing to be closed. Re-opening produces "Cannot access camera" error message screen, with access permission or some other error as cause. Reboot needed to regain camera function. Other freeze seen was a return of the viewfinder to a dark screen, and the same error message screen appearing."
