Custom rom question
I am looking at installing the omega rom on my s4 but I have a question to ask that I can't find the answer to. The rom says that it is compatible for android 4.2.2 which is what I am on (and I have checked my phones compatibility). My question is - do I need to update the normal firmware provided by Samsung when the next firmware is available and than re - install the omega rom built for that firmware when an update is available, or do you just continue to update the omega rom.
I always thought that a custom rom took the place of the stock firmware and therefore you just kept up with the latest release of that rom??? Is this correct
Please explain I am trying to learn and I am reading and watching a lot of clips but it is hard when you are starting out.
