Incorrect settings can potentially cause an app to go rogue. If the Twitter app becomes wobbly or unstable after you made certain changes to your iPhone settings, it's most likely due to those modifications. You can try reverting the modifications to the prior configuration to rule this out. If that isn't feasible, you may simply reset all of your iPhone's settings to restore the original options and values. Here's how you do it:

1. From the Home screen, choose Settings.
2. Select General.
3. Reset may be found by scrolling down and tapping it.
4. Select Reset all of the settings to the defaults.
5. If asked, enter your device's passcode.
6. To confirm the settings reset, tap the selection.
