Every time I click on the 'Messaging' app it goes all black and then says 'Messaging has stopped'. It has been doing this since for 2 days straight so I can't access my messages. I haven't been receiving messages either. From searching on the internet people said to clear cache, but when I go to the app in settings it doesn't allow me to do this. The only option is to clear data, disable or force stop. It's only this one app, the rest seem to be fine. Should i reboot the phone altogether or just delete data?
