Though the smartphone market is relatively mature (some might even say stagnant), there's been a notable lack of progress on accessibility. The simple fact is that not everyone can easily manipulate a smartphone or tablet's touchscreen, and there aren't a lot of cheap or free ways to make it easier. That's no doubt why, even in a low-profile beta, Google's voice command navigation app Voice Access climbed to more than a million downloads on the Play Store over the past two years. The app was also exceedingly popular on APK Mirror, where the original release was downloaded 1.5 million times.
