I’d imagine quite a bit of the stuttering and lag on Androids was/is a result of all the bloatware phone companies insist on putting on their phones. I’ve a 2018 OnePlus 6 that doesn’t lag or stutter because the only apps on it are the ones I choose to have on it and allow to run - it’s degoogled phone running Lineage OS (Android 14) with zero bloat and zero ads and as a result a six-year-old phone running is still buttery smooth. Phone companies have a lot to answer for… it’s lucky they don’t sell cars; they’d sell you a Ferrari and then hook up a mobile home to the back of it.
