alt Hacker Newsthis is 100% in the hands of the SoC manufacturer.
Android versions are locked to kernel versions, which are locked to binary drivers to run your hardware. there's no way around that and you can't reverse engineer or do anything if you want that SoC vendor to continue to fulfill your orders (which you're already at the bottom of the fulfilment list because of low volumes)
If this were genuinely 100% a Qualcomm limitation, I'd expect every Snapdragon 7s Gen 4 phone to be similarly stuck. But Motorola's Edge 70 Fusion uses the same SoC and was already in Android 17 beta testing in February, and Nothing's Phone (4a) and OnePlus Nord CE 6 are also slated for Android 17. So it seems the SoC isn't inherently preventing Android 17.
