Known limitations

• Mobile Detect script was designed to detect mobile devices. Implicitly other devices are considered to be desktop.
• User-Agent and HTTP headers sniffing is a non reliable method of detecting a mobile device.
• If the mobile browser is set on Desktop mode, the Mobile Detect script has no way of knowing that the device is mobile.
• Some touchscreen devices (eg. Microsoft Surface) are tough to detect as mobile since they can be used in a laptop mode. See: #32, #461, #667
• Some mobile devices (eg. IPadOS, Google Pixel Slate). See: #795, #788
• Detecting the device brand (eg. Apple, Samsung, HTC) is not 100% reliable.
• We don't monitor the quality of the 3rd party tools based on Mobile Detect script. We cannot guarantee that they are using the class properly or if they provide the latest version.
• Version 2.x is made to be PHP 5.3 compatible because of the backward compatibility changes of PHP.
• There are hundreds of devices launched every month, we cannot keep a 100% up to date detection rate.
