jQuery masked input plugin not working on smartphone

Question

Hi, I have been using the masked input plugin for jQuery for a long time.

http://digitalbush.com/projects/masked-input-plugin/

I never had any issues with the plugin until yesterday I got a support ticket regarding the plugin behaving erratically on the Driod phone.

e.g. When the user tries to enter the phone number (123)345-9646 in the phone number on the demo tab, it comes out (321)345-4696 or something like that.

I do not own a smartphone therefore I cannot really test.

I'm not sure what my best approach is solving this problem. Are there known issues for this plugin on a smartphone?

Thanks
