Sprint has just announced that a new software update is available for Motorola PHOTON Q 4G LTE smartphone. The update is pushed through OTA (over-the-air), but not all users will receive it at the same time.
The staggered rollout of the minor update will be pushed to all Motorola PHOTON Q 4G LTE devices within approximately 14 days.
According to the official changelog, the minor update includes various bug fixes that are meant to improve overall device stability.
Aside from that, no changes have been added, so PHOTON Q 4G LTE owners shouldn't expect any new features or tweaks.
Keep in mind that the update can be manually pushed to the smartphone by going to Menu / Settings / About phone / System updates / Update Motorola software. More details on the upgrade are available on Sprint's support site.
