Qualcomm just
announced that its Snapdragon 8 Elite platform will be supported for "up to eight consecutive years of Android software and security updates."
"What this means is that support for platform software included in this program will be made available to OEMs for eight consecutive years, including both Android OS and kernel upgrades, without requiring significant changes or upgrades to the platform and OEM code on the device (a separation commonly referred as “Project Treble” or the “vendor implementation”). While kernel changes will require updating kernel mode drivers, the vendor code can remain unchanged while the software support is being provided. This software support can lower costs for OEMs interested in supporting their devices longer and can show consumers the advantages of Snapdragon mobile processors and software support."
The company worked with Google on this new program, which also extends to the next five generations of Qualcomm's Snapdragon 8 and 7-series mobile platforms. It's up to OEMs to take advantage of this program, though meaning 7 years of updates isn't guaranteed for any given device.
FYI: I detailed this new program (called Longevity GRF)
in full back in October, in case you want to read more about what Google and Qualcomm have done.
