Performance is the most immediate seduction. Leaner builds strip away unused services and manufacturer constraints, freeing RAM and CPU cycles. Well-tuned kernels and governor tweaks can smooth the jitter that appears as Android ages on limited hardware. For the Nokia 2.2—whose appeal includes a pocketable form and battery longevity—a custom ROM can shift the balance from sluggish daily driver to responsive companion without changing a single component. For those who measure satisfaction in reduced stutter and snappier app launches, that transformation is tangible and intoxicating.
