Ready for update for your Nokia Lumia 1520 on AT&T? Looks like a firmware update is starting the over-the-air rollout process. We just received a tip that an update was ready, checked our Lumia 1520 and can confirm. Let’s check out what’s new in the latest firmware update for the Lumia 1520.

The last firmware update for the Lumia 1520 on AT&T that we reported came out in mid-December. It mostly featured general performance and usability improvements. (1028.3534.1347.2001)

The Lumia 1520 picked up a firmware update last month, but that was for handsets outside the United States in other markets. Those folks picked up an update that had improvements for the quality of Bluetooth connections, headset discovery and general stability/performance improvements. (1028.3562.1402.10xx)

We’re still waiting for our Lumia 1520 to finish the update process and can report back on what firmware number it lands on. We aren’t seeing any info on Nokia or AT&T’s support site yet either. Have the update already? Sound off below with the new firmware and changes you notice.

Update: Firmware version 1028.3562.1407.1001, we are hoping that this fixes the auto-brightness bug and improves screen touch sensitivity. Seeing as the firmware number is part of the same series (3562), we suspect that this has the Bluetooth enhancements, and other minor bug fixes found in the international Lumia 1520 update.

To get the update, dive into Settings > Phone Update > Check for Updates. Good luck and let us know if you notice anything different after updating.

Thanks for the tip techygeek82!
