title: Samsung Galaxy S5; Changing ISO-speed settings with camera API
body: <p>I'm trying to set the ISO for the Samsung Galaxy S5 using the Camera API. 
  The parameters which includes the ISO tag in the Camera Parameters (retreived using camera.getParameters.flatten();) are:</p>
  
  <ul>
  <li>exif_iso=0;</li>
  <li>iso=auto;</li>
  <li>iso-values=auto,ISO_HJR,100,200,400,800,1600;</li>
  </ul>
  
  <p>I quess that the exif_iso parameter has something to do with the Meta file, so i don't need that. The iso setting is what i need, and i can choose all the values stated under iso-values. If i set one of these parameters, the parameters are accepted (no exception is getting thrown). If i use a parameters which isn't stated under the values, an exception is thrown. So the value of iso are set!</p>
  
  <p>But... the strange thing is that when you take a picture, the iso setting seems to be ignored. Settings like white balance and resolution work like a charm, but i can't get the iso to change. On another phone (galaxy S2) the iso setting does work.</p>
  
  <p>In the official camera app from samsung, the iso value is editable, so somewhere in the api it should be possible! I have tried some camera apps from the play store (including open camera 1.20) but the same thing; you can change the value but it gets ignored.</p>
  
  <p>Has anyone any idea why the value is ignored? is there maybe another parameter which enables or disables this kind of settings?</p>
  
  <p>Thanks a lot :)</p>
  
  <p><strong><em>Update:</em></strong>
  I'am a little bit further. It seems to be caused by OpenCV which i also use in my app. Specifically the class CameraBridgeViewBase seems to cause the iso setting problem. Even i disable the view before taking the picture, the iso settings are getting ignored. I've build a little camera app without the use of OpenCV and the iso is set just like it should. </p>
  
  <p>If an app with CameraBridgeViewBase been running (even if you clear the memory after that) my camera test app iso settings are ignored again. I also tried the app 'open camera', the iso settings are simply ignored again. If i start the official samsung camera app, it seems like it resets the whole camera; My camera test app and 'open camera' iso setting work again after that. </p>
  
  <p>The weird thing of all is that this problem doesn't occur at all on my Samsung Galaxy S2. It only occurs on the Samsung Galaxy S5...</p>
