I feel it is possible that smaller cell phones will be the only popular devices with a small touchscreen like 3 to 4 inch screen which can be use for playing games. Nintendo and Sony probably will no longer make smaller screen size gaming devices since the Switch and Nintendo 2DS and 3DS XL with a larger screen seems more popular.
There are many thousands to millions of people worldwide who buy 4 inch screen size Google Android smartphones and flip phones with a smaller screen because these phones cost $50 or less, and the buyers prefer a smaller phone. Users can use small phones for playing simpler games like Hangman, Chess, Checkers, Tetris, snakes, and older title games like Angry Birds, Flappy Birds, and Fruit Ninja which can run on slower and more affordable phones.
