Back in September, Motorola rolled out Android 7.0 Nougat OTA update for US variant Moto X Pure edition (XT1575) with build number NPH25.200-22.

After installing Android 7.0 Nougat update on your Moto X Pure XT1575, you can enjoy Google Duo video calling app, redesigned notification panel, improved data, battery and system stability features.
