Most Android software is designed to run on smartphone screens. Google Play has been modified so tablet users can more easily locate apps that are optimized for larger displays. This is part Google’s efforts to get developers to create tablet software.
In addition, tablet users now see that the Top Paid, Top Free, Top Grossing, Top New Paid, Top New Free, and Trending lists on the Play Store include only tablet software by default. They’re still able to switch to lists with all types of apps mixed together if they wish.
The derth of software that is optimized for large displays has been hurting sales of full-size Android tablets. Because the smartphone versions of apps look better on 7-inch tablets, smaller Android tablets have been selling in much greater numbers.
