Android phone slow? I changed 2 developer settings for an instant speed boost
Many Android users experience slow device performance, but instead of using potentially risky optimizer apps, they can enable Developer Options to adjust built-in settings. Two key changes—reducing animation scales and limiting background processes—can significantly improve speed. These tweaks are especially effective on lower-end devices with limited RAM.
- ▪Enabling Developer Options allows access to performance-enhancing settings on Android devices.
- ▪Reducing animation scales (window, transition, and duration) can make the user interface feel faster.
- ▪Limiting background processes to 'At most 4' improves performance, especially on devices with 4GB of RAM or less.
- ▪Developer Options can be unlocked by tapping the Build Number in Settings seven times.
- ▪These settings are built into Android and do not require third-party apps.
