Android 5.1 Lollipop is the recent version of Android OS that is going to arrive for the Moto X (Gen 1) and Moto X (Gen 2) in the next week. The firmware is being tested before it's released to wider markets in the coming weeks.

David Schuster, Motorola's senior director of software product management, posted on his Google+ page that the soak test for Moto X (Gen 1) and Moto X (Gen 2) began on Thursday. A soak test is a testing process over a period of time before the firmware is made available to the public.

Schuster’s post states that Gen 1 users in the Australia, Belgium, Hong Kong, India, Kuwait, Malaysia, Netherlands, Oman, Qatar, Saudi Arabia, Singapore, Spain and United Arab Emirates will receive the Android 5.1 update. Gen 2 owners in Australia, Belgium, Denmark, Greece, Hong Kong, Indonesia, Italy, Malaysia, Netherlands, New Zealand, Norway, the Philippines, Poland, Singapore and Sweden will receive the Android 5.1 update. It is expected to arrive in the coming week.

Phone Arena says the Android 5.1 update will include refreshed icons in Quick Settings that can be accessed through the notifications menu. The firmware also will bring support for HD calling.

After the update, if the handset is stolen or lost, no one will be able to unlock it until Google account credentials are entered. The update also will include a fix for Android 5.0 memory leaks.

Android Pit reports that the Moto X (2014) along with the Moto G (2014) and the latest Moto E (2015) are poised to receive the Android M update later this year. There is no confirmation from Google or Motorola.
