Once you done the steps listed in the link above, the old download notification should no longer appear in the notification list. Unfortunately, an insider has told me through the email that she can't find the Downloads app through the app drawer when she wants to clear the download histories. After some further investigation, apparently this app is disabled after update to the Android 4.3 and it should be enabled again to bring them back into the app drawer.
How to fix missing apps in Android 4.3?
A confusing part to enable disabled apps in Android 4.3 is the difference between the old and the new application manager to list the disabled apps. If previously you can find the disabled app is listed in the very bottom of the All screen in application manager, now all the disabled apps will be listed under Turned off screen. Well, here's the steps to enable disabled apps in Android 4.3:
- Go to Settings.
- Tap More.
- Tap Application manager.
- Swipe the screen to the left until you find Turned off screen. You can find all of the disabled apps in here.
- In this case, tap Downloads.
- Tap Turned on button to enable the apps.
- Restart the phone.
Once the phone is turned on, now you should see the Downloads app in the app drawer and let you clear the download histories from there. For the record, you can also use the steps above to enable another disabled app or to bring back the missing apps after updating the phone to the Android 4.3. So, hope this helps :)
