FXP14x: Unfortunately, Instagram has stopped [SOLVED]

Okay, I had to touch something somewhere and since a few days ago switching to the camera tab in Instagram crashes the whole thing.

I was quite confident it has something with the face-facing camera broken in FXP but as a fix was promised for FXP148 I stayed on the patient side.

I thundered 148 this morning and while the camera flash is fixed there, the rest keeps as broken as my English.

Here's the important part of logcat:

Apparently the things crashes right after trying to open camera 1.
Unlike the rest of the civilized world, the computing area starts numbering with zero, so there's no doubt Instagram is trying to use the second (implying less important) camera - the face-facing one we already know is broken!

Cause found, how about the fix?

I suppose I could just clean the app's settings, but that's a too crude a measure for a 21st century gentleman.

A bit of searching reveals the file

/data/data/com.instagram.android/shared_prefs/com.instagram.android_preferences.xml 

sports a very interesting line:

<string name="pref_camera_id_key">1</string>

Flip the 1 to a zero:

<string name="pref_camera_id_key">0</string>

and viola!

 

 ... eh, voilà!

This fixed it.
