I've observed that after using my Moto X 2013 for two years, the Volume and Power buttons are not as tight as they used to be ( or as I've felt about them). They have a bit of a loose feel to them.

I wanna know if is it a common thing in all smartphones that their power and volume buttons become somewhat loose after an year or two if they're used extensively??

Can those repair/service centers fix them back to their original tightness??

Yep, it's quite normal. Repair center will fix it for you for just few bucks. You could do it by yourself as well (in the case you have some basic technical skills). It should be quite easy. Anyhow do it on your own risk. I didn't say it to you.
