I have purchased an iPhone from a friend, recently. I have a big problem on how to change the apple ID when updating apps into my apple ID. I have already changed the Apple ID in the settings>Store, but still the Apple ID has not changed in updating apps. I also tried removing the apps from the old apple id and reinstall the app again using my current apple ID. But still, when I try to update the already reinstalled apps, the old apple ID still pops up and not my current. I hope someone can help me because I am tired of reinstalling all the apps everytime an app updates.
