I have the same issues. The image custom field of taxonomy cause the problem.
After I added the image field, It got this javascript error when try to insert the image to the post

“Uncaught RangeError: Maximum call stack size exceeded.”

I removed the image field, then it works,

You can use this class to detect tablet https://code.google.com/p/php-mobile-detect/

include_once 'Mobile_Detect.php';

$detect = new Mobile_Detect;
 if ($options !== false && !empty($options['mobile_theme']) && !$detect->isTablet()) {

I cannot delete if the type is “Xydac Tabs”.

FYI, I tried to delete a “Xydac Tabs” field. After I change the field to other type, I can delete it.
