content: OK as a reader but has many issues. Very resource hungry unstable hard to do many simple stuff. Hard to complicate docs. Tried it for months crash 3 times in a row trying to fill a very simple 1 page sign in sheet so Im uninstalling it and trying anything else unlikely it can be worst. Could not find a way to save back into the device took to long loading  rendering some files. Crashes right after filing out info losing all data. Plus many other issues. Very disappointed.
