We rely quite heavily on the Mobile targeting feature on Short.io but we realised that bigger devices are getting ignored, specifically the Apple iPads (mini seems to be unaffected) and Android tablets.

Below are the headers we tested.

Apple:

(Not working) iPad air user agent:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.2 Safari/605.1.15

(Working) iPad mini user agent:

Mozilla/5.0 (iPad; CPU )S 18_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.1 Mobile/15E148 Safari/605.1.15

iPhone user agent:

(Working) Mozilla/5.0 (iPhone; CPU )S 18_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.1 Mobile/15E148 Safari/605.1.15

Android:

(Working) Galaxy tab a9+ chrome browser

(Not working) Galaxy tab a9+ Samsung browser

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) SamsungBrowser /27.0 Chrome/125.0.0.0 Safari/537.36

(Working) S24 Ultra

Mozilla/5.0 (Linux; Android 10; K) AppleWebKit / 537.36 (KHTML, like Gecko) Chrome/134. 0.0.0 Mobile Safari/537.36

(Working) Lenovo tab M8

(Working) S24. Ultra Samsung Browser

Mozilla/5.0 (Linux; Android 10; K) AppleWebKit /537.36 (KHTML, like Gecko) SamsungBrowser /27. 0 Chrome /125. 0.0.0 Mobile Safari/ 537.36

(Working) Pixel 9 pro

Mozilla/5.0 (Linux; Android 10; K) AppleWebKit /537.36 (KHTML, like Gecko) Chrome /135.0.0.0 Mobile Safari/537.36

It seems like Android devices with browser header "Linux x86_64" and Apple mobile devices with header " Intel Mac OS X 10_15_7" are not being redirected by the mobile targeting.
