How loud is your spacebar?
I have had my BlackBerry Key2 LE for half a year then at some point I thought the spacebar had developed a popping sound with more effort being required to push compared to the rest of the other keys.
I sent it in for warranty; and they sent the phone back without doing anything saying that the keyboard has passed the quality check. I am not sure if I am going crazy or the repair center was slacking on checking the keyboard.
For your Key2 LE, do you find that the spacebar is louder than the rest of the keys?
