Disable S Voice on Galaxy S4 for faster home button response.


Whether you know it or not, but double tap The Home key calls up S Voice, and has a built-in delay. So if you press it once to return to main screen, there will be a short pause as the phone waits for you to press a second time. If you turn off double-tap to call S Voice, you can get to the home screen faster. Just go to S Voice, press the menu key, then "Settings", and uncheck "Open with Home key".

Slide through contacts to make a call or send a message.

When you're in Contacts, instead of tapping on a contact and choosing an action, you can simply swipe left to make a call or right to send a message. The best thing about this is that you can change your mind: if you start sliding to the right to call someone, then you realize that the person is busy, you just slide back to the left and you will get a window to send a message. This has nothing to do with sliding speed, so if you're a bit slow you can "hang" in the middle of the slide, think about which option you want to select, then continue sliding in the direction you want.

Use Galaxy S4's hidden settings.

This can be done using a super app called Note 2 Hidden Settings. Yes, it's made for the device Galaxy Note 2 but also works on many Samsung devices. It simply installs user interface over hidden CSC files so you can easily modify them. Only in order for it to work, you need to get root access. You can do a lot of things like change the annoying sounds the S4 makes when the camera is not available and much more. There is no guarantee that this app will work on any device, so don't ask us to fix it just because it doesn't work for you.

Install an adaptive display.

Do you remember how the old generation of color displays on mobile phones started to wash out the colors as soon as you stepped into the light? Thankfully, technology has come a long way, especially when it comes to displays. On sunny days, we advise you to set the Adaptive Display function, so you can continue to work with your device even in direct sunlight. Go to Settings > My Device > Screen Settings > Adaptive Display. Done, you can go out!

Connect a pop-up keyboard.


Be like David Copperfield, make your virtual keyboard become floating. For those accustomed to multitasking on the Galaxy S4, the pop-up keyboard adds convenience and agility. All you need to do is open the virtual keyboard, press and hold the settings button on the keyboard, and check the box next to "Pop-up keyboard".

Extend your Galaxy S4 battery life by setting a Wi-Fi timer.

One of the disadvantages modern smartphones, produced only without the option of a kitchen sink, this is the battery charge, or rather, its lack. When you have played enough with the features and enjoy the games, the low battery warning will ring. Do you want to be able to automatically connect/disconnect Wi-Fi to extend battery life? Just go to "Settings" > Wi-Fi > "Menu" > "Advanced" > set the time frame of the Wi-Fi timer.

Use a secret bootloader.

Some network providers don't block bootloaders operating system, and you can easily install any custom ROM. But AT&T (SGH-I337) and Verizon (SGH-I545) have a locked bootloader.

The first smart phone? Try Easy Mode on your Galaxy S4.

Let's face it, we all have to start somewhere. If the Galaxy S4 is your first smartphone, then you may be confused when you first pick it up. Do not call your 12-year-old nephew to explain how to use it. Especially for this, Samsung has installed Easy Mode on its devices.


To enable this mode, you just need to go to "Settings" > then in the "Device" section, go to the "Home Screen Mode" tab, there you can select the current mode or Easy Mode.

Easy Mode has a simplified user interface (which can be customized), larger icons, and simply provides a more intuitive and understandable environment for the novice user.

Use your Galaxy S4 with gloves.

To be honest, this is one of my favorite features, however, it is disabled by default on the S4. Since I live in a climate where I often have to wear gloves, I always have to take my gloves off if I want to use my smartphone…or I need to buy special gloves.

To enable this feature, go to "Settings" > in the "Device" section, go to the "Display" tab > and check the box next to the inscription "High touch sensitivity".

Once turned on, you will be able to operate your smartphone while wearing gloves. An important note: it is more convenient to work in thin gloves, but we managed to control the smartphone with thick ski gloves.

Adaptive sound control.

Another one interesting feature The Galaxy S4 is an adaptive sound setting feature. This is especially useful feature for people who have hearing problems, or for those who just want to adjust the sound to their best comfort.


To enable the adaptive sound setting function, go to Settings> Sound> and go to the Adaptive Sound Setting tab, then follow the instructions that will appear on the screen. Once you've finished adjusting the sound, you should notice a change, but the best way to evaluate the settings is to use a smartphone with headphones.

I found that if I left my phone somewhere, I subconsciously want to check all the time to see if I have any notifications that I missed. It makes me pick up my phone, unlock it, look at the screen, and put it back down. If I'm sitting at the computer and typing (or doing something else), then I will constantly check my phone. I know. I need help.


S4 has interesting feature, which makes your phone vibrate when you pick it up if there are important missed notifications. If you took it and nothing happened, then there is nothing to check!

To enable this feature, you need to go to "Settings", then, in the "Devices" section, go to the tab "Movements and gestures", "Movements" and check the box next to Smart alerts. Really, smart function needed for people like me.

Let S4 choose your best photo.

If Best Photo mode is enabled on your S4, the camera will only take 8 shots and then suggest the best one it thinks. This is a very useful and convenient shooting mode if you need to take a group photo or capture a moving subject, such as a child or an animal.

To set this mode, you need to open the camera app, and then press the mode button, and there select the Best Photo option from the list. If you are not satisfied with the choice best photo, which made your smartphone, you can always view the 7 remaining shots and choose the best one in your opinion.
