By 2011 Snapdragon was embedded in Hewlett Packard's WebOS devices[33] and had a 50% market share of a $7.9 billion smartphone processor market.[34] By 2012, the Snapdragon S4 (Krait core) had taken a dominant share from other Android system-on-chips like Nvidia Tegra and Texas Instruments OMAP which caused the latter to exit the market.[35] As of July 2014, the market share of Android phones had grown to 84.6 percent,[36] and Qualcomm's Snapdragon chips were embedded in 41% of smartphones.[37] However, the September 2013 debut of Apple's 64-bit A7 chip in the iPhone 5S forced Qualcomm to release a competing 64-bit product, despite the capable performance of the Snapdragon 800/801/805, since their existing Krait cores were only 32-bit.[38] The first 64-bit SoCs, the Snapdragon 808 and 810, were rushed to market using generic Cortex-A57 and Cortex-A53 cores and suffered from overheating problems and throttling, particularly the 810, which led Samsung to stop using Snapdragon for its Galaxy S6 flagship phone, and Galaxy Note 5 phablet.[7][40]
