I have been developing my app for years and I am trying to be as OS-independent and browser-independent as possible.
To detect the availability of the feature, I am chechking if the constructor is available, or if some property of an object is available. I never try to whitelist or blacklist any specific OS or a browser. I have never made any part of the code behave differently for some OS or some browser. But I have reported dozens of bugs to browser developers, most of them were fixed.
Photopea runs quite well on phones and tablets. If your microwave oven passes WillItWork, it will work on it too :)
