Hey guys, i have an android 4.2.1 Samsung galaxy nexus i9250 and it's rooted. My phone is getting slower and buggier (if that is a word) and keeps crashing. I want to completely reset my phone so the root gets removed and such. Just like you got it from the factory. I have heard that a factory reset wont remove the root and i'm curious to hear if that's true. Thank you.
