Read the whole OP! Be respectful to each other and don't ask for ETAs, it's considered as being rude!

AOSP Extended is an AOSP based ROM which provides stock UI/UX with various customisations features along with the Substratum theme engine. The project has been made by cherry-picking various commits from various other projects. Being based on AOSP it provides a smooth and lag-free experience out of the box. We will constantly try to add more features and make it even better in future updates. A ROM by a user, for a user. #StayAOSP #ExtendYourDevice #BeExtended

#ExtendYourDevice Here are the Extensions! on top of AOSP! We are constantly trying to update the list. Our aim is not to provide all the features available on earth. We are not thinking of cherry-picking every feature out there. Our aim is to add important features that we think should be here and also what you think. For addition of more tweaks or features, head on to our G+ community and post the list of features that you want! Features with commits will be more helpful!

I guess there is nothing wrong in reading facts!

-Base Of the ROM & Version?

->Rom is based on AOSP.

-Why no "Incremental updates" Support?

->Actually the updates we provide monthly are heavily changed and modified than the previous builds. New stuff are merged and added. So we don't provide incremental updates and recommend clean flash.

-Does this ROM Support Substratum/CMTE?

->Yes, full Substratum support!

-Which Gapps are recommended?

->OpenGapps

-Will this ROM relock the bootloader?

->No.

-What about XPOSED?

->XPOSED is still in beta stage. We like Xposed but it messes up with the system so before giving any bug reports make sure you have xposed uninstalled.

-When Will Be the Next Update?

->No ETAs please. ROM Will be updated whenever the new build is ready. We generally provide monthly updates with latest security patches and new features.

-I am facing FCs, Bugs, Some feature is broken?

->Provide full info about your problem with logcats and the procedure to reproduce it.

->How to take Logcats?

-Adaway is not working :(

->Download it from here Adaway

-SElinux Linux mode changer app is not working nor Busy Box installer app is working.
