  this was a fresh flash of the image, i opened a bunch of apps, took a
  picture with camera app, dimissed the "photo roll" tutorial page, took
  another photo, brought some other app forward so camera app was not
- focused. Phone got hot, so i ran top and noticed camera never reduced.

+ focused. Phone got hot, so i ran top and noticed camera never reduced
+ (actually it's camera-service). Opening spread and quiting app was the
+ only way to get stop camera-app hogging cpu. I only got this the first

  Also I noticed the camera app was not "black" in the spread but showed a
  last image (tbh, unsure if it was on photoroll...but i thot i went back
  to viewfinder mode)
  
  I also notice, from playing around that camera cpu is ~50% just on
  photoroll...not doing anything, just let the phone idle on photoviewer
  and the cpu use remains pretty high (user could easily drain their
  battery)
