What was the non-GAAP EPS for QCOM in the second quarter of 2019 
econd wave of 5G devices launching in late 2019 and early 2020 to drive mainstream adoption of 5G.
Our early investments in 5G now allow us to offer the world's first modem-to-antenna system for commercial 5G new radio smartphone devices, spending millimeter-wave and sub-6 gigahertz bands including baseband, RF transceiver, RF front-end components, and millimeter wave antenna modules. This systems approach is creating a benchmark for 5G RF front-end performance. QUALCOMM is heavily engaged as a critical partner to leaders across many industries as they see 5G mobility as a foundational technology for their digital transformation.
Third, our cost structure and investment focus are aligned with the opportunities ahead. We will continue to invest where we can leverage our core competencies and bring innovative solutions to large markets. In 5G, this presents opportunities for growth in our core cellular market in addition to many adjacent industries as they leverage 5G to accelerate their digital transformation.
In summary, with our agreements with Apple, the beginning of the 5G ramp are focused on operational execution and capital return, we think we've laid the groundwork for growth in revenue and EPS and stockholder returns over the next several years.
As a management team, we are committed to driving stockholder value by taking thoughtful and deliberate actions that we believe will ensure the long-term growth of our company as you have seen.
We appreciate the positive reaction from investors and analysts through our recent announcement with Apple, especially the feedback from many stockholders over the last two weeks who have recognized and appreciated our commitment to sustaining Qualcomm's long-term differentiation and focus on technology and innovation.
I would now like to turn the call over to Dave.

Thank you Steve and good afternoon everyone. We are pleased to announce strong second quarter results with GAAP revenues of $5 billion above the midpoint of our guidance range and non-GAAP EPS of $0.77, $0.02 above the high end of our range. The outperformance in the quarter was primarily driven by QTL revenues of $1.12 billion that were positively impacted by approximately $100 million of out-of-period catch up offsetting some impacts from overall market weakness.
Additionally we saw improved QCT gross margins and operating expenses which came in lower than expected. QCT revenues of $3.7 billion were in line with expectations and the same shipments of 155 million units were within the guidance range, but below the midpoint reflecting overall weakness in global device shipments. QCT EBT margin was 14.6% for the quarter at the high end of our prior guidance range driven by improvements in gross margins. Please note results this quarter do not contain any contributions from the settlements of our disputes with Apple and its contract manufacturers.
Turning to our global 3G/4G/5G device forecast. We are lowering our estimates for calendar 2019 by another 50 million units at the midpoint to 1.85 billion units due to continued weakness in China and a lengthening of handset replacement cycle, potentially reflecting a pause in advance of 5G rollouts.
We now expect global handset units to decline slightly year-over-year offset by continued growth in non-handsets resulting in total overall unit growth of approximately 3% at the midpoint. In regards to our recently announced Apple agreements, we expect to record revenues resulting from the settlement of matters prior to the effective date of the agreement of $4.5 billion to $4.7 billion in our third fiscal quarter. This includes a cash payment from Apple and the release of related liabilities. The settlement amount will be excluded from our non-GAAP results.
Our guidance for the third fiscal quarter, we estimate GAAP revenues to be in the range of $9.2 billion to $10.2 billion and estimate GAAP EPS of $3.57 to $3.77 which includes the revenues related to the settlement with Apple and the contract manufacturers.
