Picture shown != picture taken. Breaks flash light pictures.

[Rüdiger Kupper]

MEIZU MX4 running official release 15.04(r4)

Main problem:
When you take a picture in the camera app, the app makes a shutter sound and freezes the display for a second. Then you see this picture slide to the right (presumably "into the gallery"). This would be a really nice piece of well done user feedback -- if it wasn't lying to the user. The picture you will find in the gallery is NOT the one you have seen sliding to the right. Instead, the picture actually taken is produced some milliseconds later!
You can easily show this by taking a picture of a running stop watch. I first noticed it when taking pictures of a jumping person: The "feedback picture" always showed a person in the air. It was very disappointing finding my gallery full of persons already back on the ground, when I looked at it later.

Follow up problem:
The flash light is obviously synchronized to the preview picture, not the picture really taken. This completely breaks flash light pictures.

Steps to reproduce:
1. Open camera app
2. Set flash to on or auto
3. Enter a dark room
4. Take a picture
5. Observe that the "feedback picture" that slides to the right shows a properly lit photograph.
6. Go to the gallery and observe that the picture actually taken shows complete darkness.

I.e.: Flashlight pictures are broken. You cannot take flashlight pictures with the Ubuntu phone in the current state of the app.
This seems to me like a rather severe problem?

Confirmed. Actual photo seems ca. 500 ms later than the one shown as frozen.
Easy to test by taking a photo of the screen on http://www.timeanddate.com/stopwatch/.

Problems still present in OTA 8.5 (both, the wrong-picture-shown-issue and the dark-flash-issue).
The flashlight-issue has meanwhile been reported several times, on the MEIZU (bug #1518964) and on the Nexus 4 (bug #1322121, bug #1368063).

That's how pictures taken in the dark with the MEIZU MX4 look like. The flash light was on ehile the camera focussed, then turned off. The flash fired again when the picture was taken, but obviously at the wrong moment.

Same issue with bq e4.5

The real issue is that the image is not captured from the camera's source the moment you take the picture. Instead the camera shutter sound is played along with some other behind the scenes stuff. Capturing should be the very first thing done to reduce the latency between pressing the capture button and actually capturing the image.
