The much-awaited Android M (aka Android 6.0 'Marshmallow') OS update for European users of the flagship LG G3 smartphones is on schedule and expected as early as mid-December. According to GSMArena, the phones will receive the update between 16-18 December. This roll-out is slated to begin from Poland, the report said citing a Polish-language technology portal (translated).

The Android M firmware build is rumoured to have reached the final phase of testing. After rolling out in Poland, the OS update would be extended to LG G3 users in other countries. An exact timeline for the global roll-out remains unknown.

As per earlier reports, Android M would be offered to the South Korean company's more recent G4 flagship smartphone at a later date. Key Android M features include:

  • Android Pay: This contactless mobile payment system lets Android users carry out payments at supported retail merchants via a virtual account number that contains users' account information on their debit/credit cards. This system does not give out users' exact debit/credit card information.
  • Google Doze: Google Doze automatically compresses multiple background processes/tasks activated by Android OS to improve overall battery life when devices are left unattended for a long period of time. This feature could double standby time.
  • Google Now on tap: After installation of Android M OS update, users can initiate On Tap: input. With this, additional information about any keyword can be obtained with a long press of the home button.
  • Fingerprint scanner: This functionality, along with Android Pay, enhances the overall security of the smartphone. The technology also supports biometrc sensors.
