gotchas #
low quality results #
In case low quality results were recognized; try to optimize the original photo in a couple of ways:

resize the photo - if the source photo is too large, nothing senseful would be recognized, hence resize it to a smaller photo would be a trick.
grayscaling the photo - there are cases when the image is very colorful and makes the recognition much more difficult, try grayscaling it.

PS. For more information on image guidelines, please refer to https://developers.google.com/ml-kit/vision/text-recognition/android#input-image-guidelines
running on Android #
For the first time running the plugin, the corresponding Machine Learning models would be downloaded from Google Play Services. Hence make sure:

the target phone should have Google Play Services app installed (which should be there by default).
have enough storage space for the ML models - roughly a few 10Mbs.
reachable to the internet for the downloads.

PS. Since download would take some time, corresponding UI screens should be shown to inform the users to wait for a reasonable moment.
ML-Kit version #
The ML-Kit version involved is 0.63.0.
