If you're heavily invested in Amazon's book ecosystem, then you're probably an avid Kindle user. If you also happen to use Google Books, then you've probably noticed that Amazon's offering is lacking many of the features that make Books so good, like immersive mode. Well, Amazon stepped up its game today with a Kindle app update that brings that and much more:

4.6.0

  • Read books in immersive full-screen mode (Android OS 4.4+)
  • Tap the bottom right corner of a page to lock orientation
  • Control playback from the lock screen while audio is playing in the book
  • Choose system brightness in reader settings
  • Navigate table of contents by sub chapter
  • Pair with Bluetooth devices (Permission)

Amazon, update your test device already. ಠ_ಠ

There definitely are some pretty solid improvements here, like orientation lock and better brightness controls. The update should be available for all users as of now, so jump into the Play Store to grab it.
