I deleted google maps on my phone and now cannot download it.

Open the App Library and you will find Google Maps. You probably didn’t delete it, you just removed it from your Home screen. Drag it back from the app library to the Home screen.

I the App Store you won’t see an icon for it in the corner. You will see your personal avatar icon. Tap on your personal icon. Tap on the word Purchased, then My Purchases if there is more than one choice. This will list all of the apps that you have ever downloaded. If the Google Maps app has a cloud tap on it to download it. If it has an Open button it is already somewhere on your phone.

You can also find it using Search: Swipe left to right on the first page of the Home screen to open the Search screen, enter Google Maps and its icon will appear at the top. If it is in a folder the folder name will show to the right of the icon. If it isn’t on your phone it will still appear, and you can tap on it to open it in the App Store.

Open the App Store, tap on your icon in the upper right corner, than tap Purchased, find it and download it.
