If you wanted to see how things have changed for yourself, though, you won’t have to wait for the rollout to hit you. The APK has been uploaded for all to download. This is a rather simple affair — download it, transfer it to your phone, and install it as you would any other app that isn’t in the Play Store. This version — 4.0.25 — will be installed on top of your current Play Store installation as if the update had come through over-the-air, so get to it and let us know what you think in the comments below!
