1) Cyanogenmod. Is it available for verizon note 3 running 4.3? I keep getting search results that there are while the cyanogenmod website itself doesn't offer it? I also got a Nexus 7 to try to expand my knowledge in this field, and it does have cyanogenmod installed. Now, to my understanding, it runs side by side with the Android OS while it basically strips the device's bloatware, giving you the pure, simple, raw experience of Android OS. If I were to install cyanogenmod to the note 3, how would it affect the camera functions and the s pen functions? The reason why I ask about the camera is because using my Nexus's camera and looking at some youtube videos of note 2's with cyanogenmod, it seems like it would actually be a downgrade from the note 3's stock camera. And as far as the S pen goes, I've realized that I would lose the action notes, s notes, and sketchbook for galaxy apps, wouldn't I? How could I go around that?
2) Flashing ROMS. What exactly does this do? All I can find is that it allows me to customize my phone, but I don't seem to understand to what extent.
3) Kernels. What are these?
Lol, so sorry for such basic questions. But I would really really appreciate your patience and information!
