DOCUMENT APPS
EBookDroid - This is the one I cannot praise enough. First, it's preferable over Adobe Reader because it can handle also djvu and epub files in addition to pdf. Adobe Reader does pdf only. EBookDroid provides many per-book settings in addition to book-display settings that should apply to every newly opened file. It can align two-column text as a single-column continuous scroll on the screen. It can set any of the hardware buttons to do any function. Touch screen zones are configurable finer than in Cool Reader. And it can annotate. And more. And no ads. This is the ultimate document viewer on Android.
Xodo - pdf annotation. Came preinstalled on Galaxy Note 4.
WPS Office - preinstalled on Galaxy Note 4. Shows ebooks and xls's, edits doc(x)s. I have not noticed it miss any normal office functions, so I haven't attempted installing other office software, but my needs are small currently, so I may seriously be overlooking things in this area.
QuickEdit - responds well to an attached hardware keyboard. It allows to hide the software keyboard when typing (Skype for example plays annoyingly dumb on this point). Bad: Displays ads upon saving the document.
ColorNote - upon creating a note it asks whether to start a list or a text, and then orders the items in various ways, including date of creation. Precisely what I need for shopping lists, to-do lists, and other note-taking. (I keep hearing much praise for Evernote which is preinstalled on Galaxy Note 4, but Evernote requires to create an account first, so I never used it.)
BROWSERS
Dolphin - Really dark night mode, gestures for individual bookmarks and scrolling with volume/zoom buttons.
Lightning Browser - optionally inverts colours and enforces grayscale. On the downside, the Reader function is unconfigurable crap and can suppress wrong elements, such as the main article text on Blogspot and on some newspaper sites. Also, I consider it a missing feature when it's impossible to set the volume/zoom button to scroll the webpages.
Opera Mini - no volume/zoom button scrolling and no invert/grayscale, but still probably the best and fastest browser in the mobile world. Most intuitive interface out of the box, remarkable data traffic compression and (unconfigurable) ad-blocking.
Naked Browser - has progressed greatly between a few months ago and now, so that Text Browser has become superfluous. Naked Browser is interesting because it's different and independent. A good light configurable startup page (home screen), allows setting the volume/zoom button either to scroll or zoom the pages or flip the tabs. It would be perfect if it could configure/invert/suppress website colours too, but even as it is now, it's already the old (desktop) Opera equivalent for Android.
Convert to PDF - do I want to save as pdf in order to get additional font&colour settings available in pdf viewers and to transfer the text conveniently to the e-reader? Yes, I do.
SOFTWARE KEYBOARD
Hacker's Keyboard - no comment.
SYSTEM
X-plore - dual-pane file browser.
CPU X - many system stats (not just the CPU), but I mainly use it to have a temp indicator on the status bar.
CPU Stats - a multi-core CPU graph indicator on the status bar.
CAMERA
Open Camera - a better camera app than probably anything preinstalled on any Android device.
GAMES
Shashki - Russian checkers with puzzles and openings.
