The results depend a lot on the language, the brightness, the quality of the scanned sheet and also the camera used.
It is always advisable to check the correctness of the recognition and compare it with the original document scanned.
Google Keep seems to be the most convenient app for digitizing printed documents, while Office Lens works better than others in digitizing handwritten notes.
