Compile as .doc is read as .rtf on android

Howdy,
tried compiling a document as.doc to be read on documents to go or officesuite on android, and documents to go is saying it’s an .rtf (and thus can’t read it) whilst officesuite (which is supposed to be able to read .rtfs) can’t read it or the other .rtfs in the export (as though they are all the same filetype) - it’s spitting out garbage.

Will have to stick to txt.

Cheers,

Bart
