I would prefer it to be open source, but at this point that’s not a necessity. I need an app that can open word documents, powerpoint presentations and excel spreadsheets (maybe PDFs as well but I could always get a separate app). So far I’ve tried Openoffice & Libreoffice Document reader from F-droid which worked fine for documents but simply would not load pptx or xlsx files. I’ve now installed WPS Office from the Play Store but all the conversion options are clogging up the share with… options every time I want to send a picture. I would appreciate any recommendations at this point.
On the one hand I understand that my post with SSuite was deleted, since it is not OpenSource, but on the other hand I put it because the user did not insist that it be in his request, it has a good privacy and good quality, and because there is no other decent office suite for Android that is OpenSource, at least not one that I know of. The only one I found is Collaborate Office, which is OpenSource, but for collaboration for companies and is not free, only the Demo.
