After releasing Android 5.0 Lollipop updates to the Moto X (2nd gen.) and the Moto G in India, Motorola has started sending out invites to the Moto E owners in the country, who volunteered in take part in the soak test program, to beta test Android 5.0 Lollipop update. According to a tweet from Motorola India Fans, the soak test for the Moto E is based on Android 5.0.2 Lollipop.
To be a part of this soak test, one must be a member of the Motorola Feedback Network program, and keep everything confidential. The soak test is limited to a few users so that Motorola can keep track of bugs and fix them faster, and in case if something goes wrong, only a limited number of devices get affected.
If the soak test (which might last a couple of days) progresses as expected, Motorola might roll out Android 5.0.2 Lollipop to the Moto E in India pretty soon.
