How do you restart? What happens if you click home button?

Sorry I forgot to check this.
Clicking on Home button will return to Homescreen and everything works.

So the steps are:

1. Launch Camera
2. Click on the left-bottom corner of camera menu bar to switch to Gallery view
3. Click on the left-bottom corner of camera menu bar to switch to Camera
4. Repeat 2,3 for several times ( > 5 times)
   => [issue] A page only showing wallpaper of Homescreen appears. User cannot swipe or do other operations. Clicking on Home button can return to homescreen and everything works.

Behavior in V1.3 is worse. A black screen shows up and no operation can be performed.
Please see attached log. The test starts at 11-25 15:28:14.449

I think camera or gallery or cardview apps need add some guard code for this issue. 
It's 100% reproduce rate.

Comment 8

[Preeti Raghunath(:Preeti)]

koi+ as the behavior is very bad.

Comment 9

[(inactive after 6/18) Alive Kuo [:alive]]

Reproduced on 1.2, looking.

Comment 10

[James Zhang (Spreadtrum)]

I think it's cardview or system issue. It has been fixed on latest version, can't be reproduced now.
