Usability Of Mobile Applications

I found on excellent paper that reviewed the literature on usability studies of mobile applications:

Usability of Mobile Applications: A Systematic Literature Study
By Paweł Weichbroth and others
https://ieeexplore.ieee.org/abstract/document/9042272

The papers includes a good discussion on the definition of usability. It also includes usability attributes identified for mobile applications (a whopping 75!) The most frequent attributes (the attributes that showed up the most in papers/the literature) are efficiency, satisfaction, and effectiveness. I was surprised that errors did not score higher. A reduction of errors is a significant benefit of a usable application/system.
