What was the revenue growth rate for IoT in the second quarter of 2022
lagship smartphones, the Snapdragon 8 Gen 1 at our annual Snapdragon Tech Summit. The announcement was viewed by more than 50 million people worldwide. The news Snapdragon 800 Gen 1 leads the way to a new era of premium mobile technology with category-defining enhancements across modem RF, camera, AI, gaming, security, and more. Snapdragon 800 Gen 1 is the world's first 5G modem RF solution to reach 10-gigabit download speeds.
It's the first to include commercial 18-bit mobile image sensor and the world's first platform compliant with the Android-ready Secure Element Alliance. We also announced new mobile platforms in every Snapdragon series to address global customer demand across every smartphone tier. In our licensing business, first-quarter results reflect a favorable mix in the strength of smartphone shipments. With over 150 5G license agreements, QTL is well-positioned for the future, and we continue to expect 5G to have a longer life cycle than prior generations due to its broad application across multiple industries.
Lastly, demand remains strong across all of our technologies and continues to exceed supply. Despite ongoing challenges across the global supply chain, our multi-sourcing and capacity expansion initiatives will provide incremental improvements to our supply throughout the year. I would now like to turn the call over to Akash.

Thank you, Cristiano, and good afternoon, everyone. We are extremely pleased to report strong results to start our fiscal year. We delivered our second consecutive quarter of record non-GAAP earnings, with revenues of $10.7 billion and non-GAAP EPS of $3.23. These results reflect year-over-year increases of 30% and 49%, respectively, driven by strength across both QCT and QTL.
For QCT, this was another record quarter with revenues of $8.8 billion and EBIT of $3.1 billion, up 35% and 62%, respectively, versus the year-ago quarter. QCT EBIT margins of 35% surpassed the high end of our guidance range and increased 6 points versus the year-ago quarter driven by revenue scale and operating leverage. Handset revenues of $6 billion increased 42% year over year due to greater than 60% growth in revenues from Snapdragon chipsets for Android devices. RF front-end revenues of $1.1 billion grew 7% versus the year-ago quarter, reflecting the previously mentioned pull-in of demand into the fourth fiscal quarter.
Our RF front-end revenues for Android devices grew by greater than 25% versus the year-ago quarter as we continued to see strong traction across all major OEMs. IoT revenues were up 41% year over year to $1.5 billion on continued demand for our cloud-connected intelligent edge devices. Each of the consumer, edge networking, and industrial categories grew by at least 30% compared to the year-ago quarter. Automotive revenues of $256 million grew 21% year over year on the strength of our design wins across our Snapdragon digital chassis.
We recorded QTL revenues of $1.8 billion, an increase of 10% year over year, and EBIT margins of 77%, which was above the midpoint of the guidance. These results reflect a favorable mix and slightly higher handset shipments. Turning to global handsets and our guidance for the second fiscal quarter. For calendar 2021, consistent with the previous guidance, we estimate global 3G, 4G, 5G handsets grew 7% year over year, including approximately 535 million 5G handsets.
For calendar 2022, there is no change to the forecast provided at our Investor Day with greater than 750 million 5G handsets. For the second fiscal quarter, we are forecasting revenues of $10.2 billion to $11 billion and non-GAAP EPS of $2.80 to $3. In QCT, we expect revenues of $8.7 billion to $9.3 billion and EBIT margins of 32% to 34%. At the midpoint, this implies year-over-year revenue growth of 43% and EBIT dollar growth of $1.4 billion.
For handsets and RF front end, we expect revenues to be in line sequentially as seasonal decline in Apple revenues is offset by continued growth in revenues from Android devices. Within handsets, the increase i
