Samsung Galaxy S4 can suffer lag and sluggish performance issues overtime due to several system features or worst case invasion of malware attacks. In order to bring back its optimal speed, here are seven ways to make Galaxy S4 perform times ten than you expected.

Reducing Animator Scales

Go to Settings > More > About phone > Tap build number 3-7 times > Go back > Developer options > Disable or reduce all animator scales. It will significantly speed up loading or launching of apps due to the disabled or minimised animations.

Remove Unlocking Effects

Pull down the notifications shade then select Settings. Go to My device > Lock screen > Unlock effect > None. This turns off the unlocking animation effect you've seen before and speeds up the device on unlocking the screen.

No S Voice via Home Key

Double tap the Home key > Settings > Uncheck Open via Home key. It removes the launching function and waiting delay on Galaxy S4 from the double tapping of the home button.

Software Updates

Don't forget to update your Samsung Galaxy S4 to its latest and working Android firmware. You may download using the built-in updater on the phone by going to Settings > About phone > Software updates or via Samsung Kies PC suite installed on your computer. In addition, your network carrier may have released a new firmware ready for your smartphone.

Moving Apps to the SD Card

Although some apps are not movable to SD card, explore the Application Manager to view listed apps that you can move to the external storage. No matter how big the internal storage is, the more data it stores the slower it gets eventually. Maximise the microSD card slot provided by Samsung.

Disabling Galaxy S Features

This is frustrating to most users since buying Galaxy S4 means buying the exclusive Galaxy S apps and services. Some owners prefer disabling everything to improve not only the performance but also the battery life. You may selectively enable Galaxy S apps that you usually use and disable the others.

Factory Reset

Factory reset is usually applicable if the entire system has an overall problem in terms of malware issues, registry and cache files. You may need to regularly refresh the system using factory reset to remove clogging and old data on the Galaxy S4. Moreover, make sure to use antivirus app if you frequently use S4 to browse unsecure Web sites to protect the system from spywares and viruses.
