Nokia 808 Pureview camera issues: ISO and shutter ...

Question

Hello,
From time to time I have experienced some issues with the 808. I am not really concerned with the hang and reboots but it is irritating when the camera does not work as you expect it to
1) Random hang and reboots: Can' really reproduce on demand but have seen it happen when you are using the camera and an SMS comes. I have seen more often when I am getting loads of messages on Whatsapp at once when camera is also on. The notifications keep popping up at the top and the entire phone goes for a toss. The screen might just go blank and only option is to reboot. Also at times the screen goes blank and you see the scrolling dots at the bottom just like when the phone boots.
It may be a whatsapp issue but I have also seen the phone hang reboot when not using whatsapp
2) Dark pictures when adjusting ISO:
->Pictures(1 & 2) of the cat were taken at SAME ISO settings. You can clearly see how one picture is bright like you would expect but the second pic is totally dark. Why this difference with the same exact settings?
NOTE: If you check the properties of these 2 images, the ISO is the same but the Exposure time on the bright picture is 2.9 seconds wheras the dark one is 1/3 seconds.
->The second set of picture(3 & 4) was taken outside in daylight. The bright picture is taken at ISo-50. It came out as expected. Then I increased it to ISO-800. As you can see the picture is completely dark in broad daylight.
Note: Image properties of the bright picture shows exposure 1/143 seconds and the dark picture shows 1/2146 seconds ??? Now thats a very fast shutter speed
-> SLOW automatic shutter speed: As mentioned in http://discussions.nokia.com/t5/Nseries-and-Symbian-Smartphones/Several-severe-Issues-with-the-Nokia...
Pictures of objects in motion are always blurry. Also I assure you my hand isn't shaky. Even i think the auto shutter speed is very low because almost every moving object i click is blurred. Dont expect it from this camera. 
Check out picture number 5. It was taken in Creative mode with everything set to AUTO. There is sufficient light however you can see the face on the right is blurred. As you can see, a perfectly good moment could not be captured perfectly because of this blur. The head wasnt too fast to cause such a level of blur. Its almost impossible to take sharp live action shots because of this.
-> Shutter sound lag: Again from:http://discussions.nokia.com/t5/Nseries-and-Symbian-Smartphones/Several-severe-Issues-with-the-Nokia...
When clicking with low ISO settings, the shutter takes more that 2-3 seconds but the shutter sound comes as soon as you click. Because of the sound the subject things that picture has been clicked and moves causing blurred pics. Can you make the sound come only AFTER the picture has been completely clicked.?

Answer 1

I am only to be able to help you on the pictures part.
1 and 2. I do notice that the picture 1 is brighter compared to the picture 2. It is hard to say that the sky was focused on the picture 2 as the sky is blurred, which means the cat is right in focus. But, you can make them brighter by increasing the exposure value and the ISO. Another possibility is you're focusing on the sky but it is out of focus.
For number 3 and 4, try it again, just to make sure. It shouldn't work like that.
For picture 5, try increase the exposure value as this may decrease the shutter lag. Another way to frezze the moving objects is by using the Xenon flash.
Hope this helps.
If I have helped you in any way, give me a kudos!
