in built apps update Every minute my phone seizes and "unfortunately, measure has stopped" pops up. It makes my phone slow. Under application manager in settings, the app is there but I can't update it.
You can only update an application from the Application Manager if the application has an update in the Google Play Store. If there is no update, it will not be available in the Application Manager.

Try to delete and reinstall the app. If the issue continues even after that, send a bug report to the app's creator and find an alternative if the issue cannot be resolved by the creator.
