Running this ROM (first time changing rom's) and this is great since I started using MS3 as well.
Just a few things I've noticed
1. when typing a text or entering a new email or pretty much entering any text on a new email account setup s2u2 likes to start and when you slide to unlock it takes you back to the home screen (this is on a new install no changes have been made to s2u2)
2. like what has been stated above battery life seems to have been cut way down. I do keep bluetooth on and have it connected to a charger always but when the phone sits on the desk not charging and goes from mid 70% to 8% in just over a hour something is wrong (did not have this issue with stock)
Other then that I love the new speediness of my phone, I'm still playing around on this new rom and have to say thank you
Oh forgot to mention this is on the sprint 6.1 ROM
