I can't open any apps that I install.

[Ocean Chan]

If I go into the play store and search for any app, go to a random app and click install, it will load and say installing as if it was installing the app. When it finishes, there is only one button, the uninstall button. I have no idea where the open button is, and I can't find the app anywhere. My phone is a ZTE. I've tried restarting my phone, and I turned on the install from unknown sources. Still nothing. Please help.

There's no "open" button, you find the app in the app drawer (the icon with the 6 dots at the bottom of the screen) and tap it. If you want it on the home screen, long-press it and you'll see your home screen - then just drag it there. (Android makes a shortcut on the home screen.)
