I have changed the following function to keep the exif data when using 
File_URI, please use or make change as you see fit, any other suggestion or 
improvement is most welcome too:

 

- (NSData*)processImage:(UIImage*)image info:(NSDictionary*)info 
options:(CDVPictureOptions*)options
{
    NSData* data = nil;

    switch (options.encodingType) {
    case EncodingTypePNG:
    data = UIImagePNGRepresentation(image);
    break;
    case EncodingTypeJPEG:
    {
    if ((options.allowsEditing == NO) && (options.targetSize.width <= 
0) && (options.targetSize.height <= 0) && (options.correctOrientation == NO) && 
(([options.quality integerValue] == 100) || (options.sourceType != 
UIImagePickerControllerSourceTypeCamera))){
    // use image unedited as requested , don't resize
    data = UIImageJPEGRepresentation(image, 1.0);
    } else {
    data = UIImageJPEGRepresentation(image, [options.quality 
floatValue] / 100.0f);
    }

    //if (options.usesGeolocation) {
 NSURL *assetURL = [info 
objectForKey:UIImagePickerControllerReferenceURL];
 
    //NSDictionary *metadata =[info 
objectForKey:UIImagePickerControllerMediaMetadata];
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    dispatch_semaphore_t sema = dispatch_semaphore_create(0);
    dispatch_queue_t queue = 
dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0);

    dispatch_async(queue, ^{[library assetForURL:assetURL

    resultBlock:^(ALAsset *asset)  {

    NSDictionary *controllerMetadata = 
asset.defaultRepresentation.metadata;
   
    //NSLog(@"metadatacontrol %@", controllerMetadata);
    
    //NSDictionary* controllerMetadata = [info 
objectForKey:@"UIImagePickerControllerMediaMetadata"];
    if (controllerMetadata) {
    self.data = data;
    self.metadata = [[NSMutableDictionary alloc] init];
    NSMutableDictionary *metadataAsMutable = 
[controllerMetadata mutableCopy];
    //NSMutableDictionary* EXIFDictionary = 
[[metadataAsMutable 
objectForKey:(NSString*)kCGImagePropertyExifDictionary]mutableCopy];
    NSMutableDictionary *EXIFDictionary = 
[[metadataAsMutable objectForKey:(NSString 
*)kCGImagePropertyExifDictionary]mutableCopy];
    NSMutableDictionary *GPSDictionary = 
[[metadataAsMutable objectForKey:(NSString 
*)kCGImagePropertyGPSDictionary]mutableCopy];
    NSMutableDictionary *RAWDictionary =

    if(!EXIFDictionary)
    EXIFDictionary = [[NSMutableDictionary dictionary]

    GPSDictionary = [[NSMutableDictionary dictionary]

    if(!RAWDictionary)
    RAWDictionary = [[NSMutableDictionary dictionary]

    //Add the modified Data back into the image’s metadata
    [self.metadata setObject:EXIFDictionary 
forKey:(NSString *)kCGImagePropertyExifDictionary];
    [self.metadata setObject:GPSDictionary forKey:(NSString 
*)kCGImagePropertyGPSDictionary];
    [self.metadata setObject:RAWDictionary forKey:(NSString 
*)kCGImagePropertyRawDictionary];

    //NSLog(@"enter gpsdictionary %@", GPSDictionary);
    //NSLog(@"enter exifdictionary %@", EXIFDictionary);
    //NSLog(@"enter rawdictionary %@", RAWDictionary);

    //NSLog(@"enter self.metadata %@", self.metadata);
    if (self.metadata) {
    //this will be the data CGImageDestinationRef will 
write into
    NSMutableData *newImageData = [NSMutableData data];

    CGImageSourceRef sourceImage = 
CGImageSourceCreateWithData((__bridge CFDataRef)self.data, NULL);
    CFStringRef sourceType =
