Phoenix AEX is the extended AOSP based custom ROM available for the OnePlus 3 and the OnePlus 3T. The ROM pulls out stock UI/UX with the Substratum theme engine onboard.

If you don’t like sticking with the stock ROM of your OnePlus 3/3T, you have a number of custom ROMs to go with. There are stock based custom ROMs and then there are the complete and pure custom ROMs. Stock based custom ROMs are good to go with as far as you care about a bug-free and a smooth system.

It’s built out of different sources that are open. You’ve already had a look on the features offered by this ROM. Now if you have made up your mind to flash it on your OnePlus 3 and OnePlus 3T, then let us handle it from here.
