replying to scav ; I don’t know what the probability of something going wrong is, but it went smoothly enough for me. I just grabbed it from the Play Store the other day (so was surprised to read here that it got removed). If you were going to install it, you should OF COURSE back up your phone before doing the install process.
Yes my Samsung (and ATT) crapware is gone now. Tethering so my phone can offer an internet connection to my laptop when needed seems to work very well (I know installing CyanogenMod isn’t the only way to get tethering but the feature is there by default). Homescreen and other things seem more customizable, battery life and performance and stability seem fine. No real complaints here so far. More info here ;
