The next flavour of Android Lollipop is already out in the wild, despite no official announcement from Google. Android 5.1 builds running on Android One devices in Indonesia appear to have surfaces few hours ago.
The new Android version was spotted on the Evercoss A65 and Nexian Mi438S, both low end MediaTek Android One devices. No changelogs were posted but it’s fairly reasonable to assume that Android 5.1 Lollipop packs a whole bunch of fixes that have been plaguing some Android 5.0 devices such as the Nexus series which experienced the infamous memory management bug. New version of Google Apps also came preloaded and few UI elements also appear to have been tweaked, a new drop-down was spotted underneath the WiFi and Bluetooth quick toggle icons.
