I switched from an Evo to a NS4G, and while I love the phone, I have been having issues hitting the spacebar and the alt key while typing. I first thought this was because of the smaller screen compared to the Evo, but then I looked a little closer. While testing my phone, I noticed that most of my button presses had to be near the top of said button to even work. If I press the spacebar or another bottom-row key near the bottom 1/2 of the button, it won't register at all. This explained why sometimes I'd write entire sentences without spaces! I compared it to my friend's Nexus S on T-Mobile, and his screen was dramatically more responsive where mine seemed to fail. Same goes for a friend's Evo and another friend's iPhone. Anyone else notice that the lower row of keys is very picky compared to other phones?
