Manually flashing ZIP files or modifying system folders can make your device unbootable if done incorrectly. Always backup your data before attempting a system-level fix.
Apps like Pika! Show or Battery Charging Animation 3D allow you to download and apply professional-looking animations without needing to flash a ZIP file.
If you aren't trying to fix a broken system file but just want a new look, you can use built-in features or apps that don't require risky system modifications.
