It is not working, but there’s a patch. Hopefully the author sees this too to make it official…
I had to make these modifications to the code:
mobile-smart.php, line 858:
old: $is_mobile = $this->DetectMobileQuick() || $this->DetectIpad();
new: $is_mobile = $this->DetectMobileQuick() || $this->DetectIpad() || $this->DetectAndroidTablet();
And update the lib/mdetect.php file with the latest version:
