There is a huge variety of Android devices and we can only test on a small subset. FoCal is an intensive application and we recommend using newer mid- to high-end Android devices with at least 4GB of RAM.
NOTE: The free version of FoCal Mobile deliberately offers the ability to connect to a camera, Verify Setup and run AF System Check, so you should ensure that these all run reliably before purchasing a subscription.
