-Installed Android 6.0.1, it wiped out most, if not all of the bloatware. This also improved the auto rotate issue, wasn't a complete fix but I hardly notice if it fails anymore. -Look up rotation control under the app store, there are some good apps that give you complete control of the rotation,...
-Size, I like the big screen, and a clear picture; -The camera is great! I have read bad reviews on it, I'm guessing they didn't try to use the HDR functions; -Expandable, I currently have a 200gb microSD in mine.
-Auto rotate doesn't work all the time; this is a known problem with this phone
