Wifi Power Saver Mode Disabler - [ROOT] is required to work.

Unlock high performance Wi-Fi for maximum bandwidth and response. Power Saver mode is enabled by default on most Samsung devices which can slow Wifi performance and causes latency.

Test the response by pinging your device from a computer whilst Power Saver mode is enabled / disabled. You will see the difference.
