A new report says that Samsung, Qualcomm and AMD have teamed up to bring FSR to mobile devices. The tech will be shown off alongside the Galaxy S24 series next year. https://www.notebookcheck.net/Galaxy-S24-could-get-native-FSR-support-thanks-to-collaboration-between-Samsung-Qualcomm-and-AMD.764878.0.html
Samsung must increase updates to 5 years of the OS and 6 years of security patches across its entire range from the S21 series onwards. The S24 will come out with ONE UI 6.1 focused on Artificial Intelligence, this new layer should be able to be updated in the rest of the models in the Galaxy range.
FSR has been in mobile for ages - it is already in Unreal Engine (Just Google for Unreal Mobile FSR). It looks like the original article was on ajunews and contains a bunch of inaccuracies (e.g. Samsung had ray tracing in Exynos 2200, article states that it will be new in 2400, and also describes FSR as a Generative AI technology, when in fact there no AI involved in FSR at all. MediaTek has also had these technologies for a couple of years now, so it is not fair to state that they are behind.
