Soak testing usually indicates that an end user release is just around the corner. According to Schuster's post, soak testing for the first-gen Moto X has begun in Belgium, Italy, Netherlands, Spain, Australia, Hong Kong, India, Kuwait, Malaysia, Oman, Qatar, Saudi Arabia, Singapore and the United Arab Emirates. The second-gen Moto X (2014), meanwhile, has entered soak testing for the retail channels of Australia, Belgium, Denmark, Greece, Hong Kong, Indonesia, Italy, Malaysia, Netherlands, New Zealand, Norway, Philippines, Poland, Singapore and Sweden.
In some regions, the Moto X line has already been updated to Android 5.1, but this mass wave of soak testing should bring many other nations up to scratch. Here's to hoping that everything runs as planned, and those in the aforementioned countries do finally get their long-awaited Android 5.1 Lollipop update.
