hey guys wassup.I got a small problem here.I noticed this a few days ago.

While playing gta i was trying to reverse and The Square button is for reversing rite, so i noticed that my square is button is kinda loose.Like for example if i press the triangle or O or X button when you leave ur fingers of them a small noise kinda comes out of it but when i press my square button down its like kinda loose.I dont know how to explain it but,its not loose as in shaky or sumting but it feels weird from the other buttons.Gta is the only game i own and i hardly use the square button
So if i give to shop and ask them to get it repaired, and if they send it to sony then they r obviously gonna upgrade my firware.Ermm whut to do.Also if u play games like bleach or street fighter u kinda gonna do like fast moves so ur obviously gonna put sum pressure on the buttons,so if one buttons gets spoilt is it possible to replace it.
