Q: I have uninstalled an app but after some time when i want to download the same app from app store it starts but suddenly stoped at the middle of the downloading process

Hi there azharhossain,

It sounds like you are able to start the installation process but it seems to get stuck on an iOS device. I would first delete the app if it is sitting on your Home Screen incomplete and unresponsive to downloading:

Delete an app

1. Press and hold the app until it jiggles.
2. Tap the  in the upper-left corner to delete.

You might be asked to confirm that you want to delete the app. If you see a pop-up that says, "Deleting [app name] will also delete all of its data," tap Delete.

From: Delete music, movies, apps, and other content from your iPhone, iPad, or iPod touch

Then quit the App Store and the Settings apps:

Force an app to close in iOS

1. Press the Home button two times quickly. You'll see small previews of your recently used apps.
2. Swipe left to find the app you want to close.
3. Swipe up on the app's preview to close it.

 
When you have done that restart the device and test the issue again:

iOS: Turning off and on (restarting) and resetting
