Some photo editors seem to make an app freeze when cropping a picture taken by camera with allowEdit=true.
My mobile phone shows two photo editor apps to crop pictures, Crop photo and Crop picture. Actually Crop photo works perfect. But if the Crop picture is chosen, it prompts to set range to crop the picture then save it but the editor app stop responding and it ends up making the entire Cordova app unresponsive. Adding that, the Cordova app cannot be reopened regardless of an attempt to kill the hanged process, unless device is rebooted.
But strangely the app can crop pictures without any problem when the pictures are retrieved from photo albums (so it's when sourceType is set to PHOTOLIBRARY or SAVEDPHOTOALBUM) and the cropped picture is finely sent to Cordova app.
Unfortunately I have not identified the reason of this due to limited time at this moment but raise this issue.
