If I don't use a case / bumper/ screen protector (especially case and bumper) will my IPhone have a higher chance of going wrong? For example, whenever I put down the phone on table, I won't put the phone very down very slowly and very carefully (of course, I won't do it very violently too), will frequent "collision " of the unprotected IPhone will give strong "vibration" or "collision" to the internal electronic components, making it easier to go wrong or malfunctional?
Thank you
