I am new to the Galaxy S4 and I have this thing that says Lollipop update, do I really need this or can I somehow ignore it and keep things they way they are?
You can just ignore it , lolipop just gives the s4 a new ui , which is more white and thats not amoled friendly , if you have 4.4.2 Just stay on that , i got better battery life on kitkat
