Specifically my question's closure. It's not about mobile phones at all, it's just that I didn't know it was being closed at the time so I had no chance to "defend" it.
The close reason is key. Editing for clarity and focus is the major option to look at.
Edit the question to be relevant to the accepted topics for Super User. If it's about mobiles, eReaders or other electronic devices, but are not connected to the desktop or laptop, it's not on.
If it was closed as subjective and argumentative, either trim the fat and boil it down to a specific problem that needs fixing or give it up.
Edit in plenty of details and narrow the question scope to less than a grab bag of thoughts plucked from the clouds.
Comments are helpful, but the question content is the most vital aspect.
