I published a computationally intensive app for Android 2.1+ that has been very well received.
But there have been some negative reviews and comments pertaining to performance. These are from people who want to use the app, but can't because they say it's running way too slowly.
It works smoothly on my Sprint Evo 4G (Android 2.2). Moreover, from the many positive comments, I can see that many people do not have performance issues running this app on their devices.
Let's assume there are no programming issues and the code is maximally efficient. I am considering blocking the app from Android 2.1, and making it accessible only for 2.2 and above.
Have other people encountered this situation? Are there really some 2.1 phones out there that are very slow, say, using the speed of the Evo as a benchmark?
