Any tips on my first "non-sense" Android?
Yeah... Enjoy it! I went Evo 4g to NS4g because of a broken screen. I was a little concerned because, while it IS an upgrade, I wasn't certain if it would be a big jump like my previous upgrades have been. Suffice to say, I'm glad I went with the NS4g. I bought online and picked up in store. Paid $30. I feel like it was a good deal.
The screen alone is a HUGE step up from the Evo. I have a brighness widget I sometimes forget about til mid day when I'm looking at the phone and frustrated that I can't see anything... Then I remember the brightness is at it's lowest setting! A single bump and it's brighter and more clear than my Evo ever was. Color is amazing on this phone, too.
I rooted, but there certainly wasn't the same level of need to root on the NS4g as there was on the Evo.
Have I mentioned how fast this thing is? Well, I will now. It's FAST. No lag between screens, apps start quicker and run better, start up/shut down and reboots happen in THE BLINK OF AN EYE. (And I had my Evo running pretty quickly, or so I thought.)
The other thing is, It's really light. It disappears in my pocket in a way the Evo never quite did. Some folks say the build quality seems cheap. I get that... I loved how the Evo felt like a serious piece of equipment. The NS4g sure doesn't feel like it would do the same damage if I chucked it at someone, but then again... IT'S A PHONE!!! Throwing it is generally bad.
So there ya go. Tweak to your hearts content. Enjoy Android the way Google intended. Get a case and a screen protector to keep her shiny. Oh! Download "NoLED" from the market, cause for some reason Samsung saw fit to include NO LED notification on this phone. That was my sole issue with the device until I found NoLED.
Have fun.
edit-
After having this phone for a couple weeks, I wonder if anyone will tempt me away from this "pure google experience". I plan to stick with the Nexus (in whatever form it takes) for quite some time.
