The leak was spotted on the official Android One website, which stated that affordable Android One phones run “the latest and fastest version of Android (5.1 Lollipop).”
While many punters took it for nothing more than a typo, it quickly emerged that Android 5.1 is real. German tech site Android Pit found three Android 5.1 build numbers for the Nexus 5, 9 and 6.
The site also managed to confirm that Android 5.1 has already made its way out to some new Android One devices, but there is still no word on an OTA update for Nexus devices.
Late last year, Android Pit managed to dig up a changelog for Android 5.1, which listed a number of bug fixes, but no new features:
- Silent mode added after missing on Android 5.0
- General improvements in system stability
- Improved RAM management
- Fixes for sudden app closures
- Improved battery management
- Excessive consumption of network devices when used Wi-Fi fixed
- Issues with wireless connections fixed
- Problems with Okay Google function solved
- Notifications problems solved
- Some sound problems experience by certain devices fixed
- Other improvements and changes
- Changes in the Material Design color palette (after users complaints, possibly for a higher version though)
As always, the problem with Android 5.1 and every other update is that very few devices will get it in any reasonable timeframe.
