Will deleted apps be restored when I reset factory data? I need to reset my phone to get it back to what it was like when I first bought it. If I reset it to factory settings, will the apps I've deleted be restored as well?
If not how do I find and restore those apps?
Inbuilt apps that you deleted/disabled will be restored. Any apps that you installed from Google Play and weren't pre-installed on your phone wont't be restored.

You will have to redownload those apps again which you want to use again. Also give this a read and the linked question inside.
