Probably the coolest thing you can do on a Note 2 is root and install custom ROMs. Well, a lot of people just “don’t get it” and stay on stock firmware, which actually is super laggy and you are limited to features Samsung gives you.
There’s a better way to use your Note 2 by installing custom ROMs that give you Galaxy S5 and Note 3 features. Of course, that is if you want to take advantage over everything that your Note 2 has to offer and root it.
For AT&T, T-Mobile, GT-N7105, Canadian, and GT-N7100, you can grab the Ditto Note 3 ROM, which is based on latest Android 4.4.2 TouchWiz with S5/Note 3 features.
For Verizon Note 2, you can grab R3Ds ROM, which also gives you Android 4.4.2 TouchWiz with S5/Note 3 features.
For GT-N7100, you can also grab Dr. Ketan ROM, which is very similar to Ditto Note 3 ROM along with TouchWiz S5/Note 3 features.
