                    isNeedCamera: true,
                    maxNumberFiles: 10,

           let mediafilepicker = new Mediafilepicker();
            mediafilepicker.openImagePicker(options);

            mediafilepicker.on("getFiles", function (res) {
                let results = res.object.get('results');
                console.log(results);
                ...

Additional context
I've tried to reproduce this on the mobile phone and the number was increased by 3!

I have the same issue, it duplicates every file.

I have the same issue, it duplicates every file.

The duplicated files have the same filename. Just solve it with own codes.

 let results = await new Promise<any[]>((resolve, reject) => {
                this.mediafilepicker.on("getFiles", function (res) {
                    let results = res.object.get('results');
                    resolve(results);
            })

results = _.map(_.groupBy(results, r => r.file), v => v[0]);

Will this code fix the files count? By the way- this bug was the last straw for me. After that I've migrated to Xamarin. There are much less cryptic bugs in there
