I sometimes have a lot of down time at work and want to do some fairly serious writing as it is often the only time I have available. The problem is that I can't find a good word processor app for Android. The phone (a Samsung S4) came with Polaris Office, but that crashes the phone every time I try to open it. I looked for an Android version of Open / Libre office, but the one I found is like $90 after 2 weeks. I also looked at Google dpcs, but a number of reviews said it tends to choke on large files and randomly crashes, losing work. I would prefer not to use MS Word,. What else is out there and does any of it work well?
