Its alright, everybodys gotta start somewhere
Also this is very difficult to explain, so please bear with me
A custom rom basically is like different versions of Android within the version. For example, on here we use mostly android 2.3.5 based custom roms. Right now you are probably on stock. Different roms, or "versions" of the platform, can come with different features. The biggest one between the stock rom that ships with the phone and the majority of custom roms we have here on our forum is the ability to overclock the phone, though that is really the kernel. Usually the maker of the rom will throw in a modified kernel to go with their rom. The ones here can go up to 1.8 GHz, as opposed to the stock 1 GHz when you first get your phone. Also, most of the bloatware or the apps that come preinstalled on the phone are removed from the rom to (1) free up space and (2) stop unwanted notifications about updates. Some even run as background processes even though they're totally uneccesary so they're a waste of battery life as well. Theres so much more but it can't be all put into this post, so its really a matter of exploring and finding for yourself. This Warp has tons of potential, as the developers here have proven already. Try out different roms around this forum, but remember to be careful not to install ones from other phones OR ELSE YOU WILL END UP WITH A VERY EXPENSIVE PAPERWEIGHT (which is very stylish and has a oil proof battery cover).
Have fun finding the right rom for you!
