I am using the digitalbush masked input jQuery plugin. It is working fine in web browsers and the iPhone browser perfectly, but it is not working for Android mobile devices.
The library used in the question is no longer being maintained. I switched my application to jQuery Mask Input as it works great, has a very similar base init call to the former library making for an extremely easy transition and, at the time of this post, jQuery Mask Input is regularly maintained at GitHub.
My issue was with the phone number masker moving the cursor back to the second position when 3 or 4 digits were entered. The cursor continued to act odd after that point. The problem was noticed using jQuery Masked Input v1.4.1 (old library) in android tablets using Chrome post major version 51.
