Is it just me or does it seem like it takes less pressure to register a press than when it was new? Maybe it's just my imagination, but it almost feels different after just a week.
I used my wife's SE this week and the physical home button felt strange. I'm now accustomed to the 7's button and the one of the SE felt squishy and "cheaper" somehow.
It's the same to me, when my phone was new and now. However I found out it's pressure sensitive. If I press the home button lightly then it feels spongy, but if I press it firmly then it feels like a hard click.
It's probably because you were more careful with it when it was brand new. I find that I even touch the screen softer for the first couple of days, lol.
