Swift-li is a blend of different libs of two ROMs , and has tweaks. Mine one is pure LeWa out of the box. If you guys want me to add any mods , I will be happy to do so.

please see this: and also the links therein.
does LeWa OS 4.1.2 v13.05.04 rom have solutions for the above issues found in swift-li v3 rom?

edit: ok, dev has answered the first part. please check rom for the other issues mentioned and comment.
thank you.

I am not sure about USB otg in my LeWa since I don't own otg cable. You may flash and check and tell me here.
Second, mount points are fixed in the ROM and external and internal SD card Mount correctly.
