Problem: My S7 Samsung which I bought 2 months ago has a dead screen but LED is flickering red to show some messages have been received. I am trying to connect charger but it seems its not responding again. Could it be the phone has crashed or what?
Solution: If we have to look into the symptom that your phone is having now, there are two possibilities we need to consider that may have caused the issue; it could be that the device has hardware or software problem. As you indicated that the LED is still blinking once it is connected to the charger, that’s a clear indication that the hardware of the device is fine and most likely this is only a software problem caused it. So, to rule out the issue we recommend you to perform the basic troubleshooting procedures on your phone. Here’s what we want you to do:
Step 1: Try to force reboot your phone
It’s a very simple procedure but it is very effective in fixing issues like this. In fact, it might be the only procedure you need to do. If the issue is caused by a glitch in the system, there is a chance that the issue will be resolved after this method. Press and hold both Power and Volume Down keys for 10 seconds and wait until it boots up. You can do this while the phone is plugged in or not.
It is actually a soft reset which is very effective in dealing with system crashes brought about by some apps or a firmware update. Don’t go to other procedures unless you’ve done this.

Step 2: Let the device charge for 10-15 minutes for the battery might be drained
The purpose of charging the device for several minutes is to determine the battery’s condition if it is defective or not. Because if it is, then there’s no point to continue the troubleshooting, instead, bring your phone to the nearest shop in your area or call the retailer store where you purchased the device and ask for a battery replacement. However, after 10-20 minutes of charging and the device responds or the charging icon appears on the screen, then obviously the battery was totally drained during that time and that’s the reason your device could not boot up. So, while connected to the charger try to perform again the first method you do and see if will respond. If it persists, move over to the next method.
Step 3: Boot in Safe mode to verify if an app triggered the problem
By booting the device in safe mode we can easily determine if there’s a culprit preventing your phone from booting up successfully. In this android environment the third-party apps won’t be loaded in the firmware and only pre-installed apps will be running in the system. So, if your phone turned on while in this state, then there’s an app you need to find and uninstall it to resolve the issue. This is how to boot in safe mode:
- Press and hold the Power key.
- As soon as you can see the ‘Samsung Galaxy S7’ on the screen, release the Power key and immediately hold the Volume Down key.
- Continue holding the Volume Down button until the device finishes rebooting.
- You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.
Step 4: Try booting it up in Recovery mode and then reset it
But if your phone still unable to power on, try to do the next method by deleting the system caches of your device. These are the temporary files stored in the directory that your phone is using to help things to load quickly like: launching an app, browsing web pages and other stuff that you want to do on your phone. So, if these caches are not compatible to the system that may be the reason that the firmware could not load up successfully and caused it to crash. In wiping the cache partition we are forcing the device to create newer and fresher caches that can run smoothly to the system. Just follow these steps to delete the system caches:
- Press and then hold the Home and Volume UP keys, then press and hold the Power key.
- When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
- When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
- Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
- Once highlighted, you may press the Power key to select it.
- Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
- Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
However, after forced reboot, safe mode and deleting the system caches but the device still unable to turn on, then we can’t do anything about it. Instead, you can bring your phone to the nearest shop in your area to be checked and fixed by the tech if there were damaged components inside.

The Galaxy S7 and S7 edge provide a suite of new features that make the devices more natural and more seamless to use. Here’s a look at 14 useful features on the Galaxy S7 and S7 edge that you might have missed.
1. Customizable App Shortcuts on Lock Screen
When the Galaxy S7 and S7 edge are locked, two apps can be placed in the lower corners for easy access. Choose the apps you use the most—whether the camera, phone, photo gallery, S Health or even third-party apps—and the Galaxy S7 and S7 edge can provide you with faster access.
How to Set Up: Setting > Lock screen and security > Info and app shortcuts > App shortcuts
2. Multiple Lock Screen Images
For your Lock screen’s wallpaper, you can now select multiple images from your Gallery to change the look each time you check your lock screen. It allows you to choose up to 30 images.
In addition, if you long press the display while the lock screen is on, the time and other information on the display disappear leaving only the wallpaper image. That allows you to see your lock screen image without interference from any on-screen information.
How to Set Up: Settings > Wallpaper > Lock screen > Select From Gallery and choose the photos (up to 30)
3. More Ways to Manage Apps from Home Screen
With the Galaxy S7 and S7 edge, you can now easily move apps around your home screens and search for apps more simply.
To move icons to different Home screens, long press an icon, and then drag it to the Move apps icon on the upper right. The Move apps is a temporary container for managing several applications at once. Then tap or drag it to move it to another page.
In addition, you can look for an app by name in the app tray by selecting “Search” at the top of the screen.
4. Show All Apps on Home Screen
Usually downloads all go to an app tray, but if you don’t like that way of organizing them, the Galaxy S7 and S7 edge give you an alternative method. Choosing “Show all apps on home screen” gets rid of the app tray, and moves all the apps to the Home screens.

5. Identify Unsaved Callers
When you receive a call from a number not in your address book, the Galaxy S7 and S7 edge can check to see if that phone number is suspected of being a spammer or even a fraud-related number, and what the risk level is. Depending on that analysis, you can choose to block or report the number.

6. Display Scaling
Display scaling lets you optimize the DPI (Dots Per Inch) settings of your display. You can either choose to stay as Standard or change to Condensed. Condensing your display lets you view more content on the screen at one time with smaller icons, controls, and text.
How to Set Up: Settings > Display > Display scaling
7. Icon Backgrounds
For the Galaxy S7 and S7 edge, the look of the icons has been updated to be more unified and natural. For native apps, the icons all come in a “squircle” shape (a square with rounded edges), creating a pleasing and organized appearance. For third-party apps, users can turn on the Icon background, which creates a squircle container background for all those icons, too, unifying the look of all of a user’s apps. In addition, many icons now offer two different styles—a traditional flat look, and a more 3D look.
How to Set Up: Settings > Display > Icon backgrounds
8. Schedule Auto Restart
Often restarting a device is one of the best ways to keep it running efficiently, as it clears out the system and ensure new apps and updates are operating properly. Auto restart ensures that your Galaxy S7 or S7 edge gets a regular restarting, so you don’t have to worry about remembering to do it manually. The function also takes care to prevent restarting from happening at inconvenient times, so it only occurs when the screen is turned off and the device is not in use, but there is at least 30 percent of the battery power remaining.

In addition to these innovative features newly added to the Galaxy S7 and S7 edge, a variety of other useful functions are also available on these flagship Galaxy devices.
9. Always On Display
Now you can check on notifications, missed calls, the time, date and more without ever unlocking your display. Always On Display puts that information right on your screen, freeing you from activating your display to check them, and without draining your battery.
How to Set Up: Settings > Display > Always On Display
10. Cross App
With Cross App, you can use apps from within certain other apps. For example, while chatting with a friend in the Messages app, you can access photos and videos and share them, or open a URL and check out a web page, all without exiting the messenger first.
Cross App is automatically integrated with the Galaxy S7 and S7 edge. When using the Messages app, just click on the paperclip icon on the left of the Enter message panel. That gives you the choice of Camera, Gallery or Other. Camera lets you take photos or record video and send it directly to the person you are chatting with. Gallery lets you select photos and videos saved on your device. Other offers a range of apps, including Audio, Voice recorder, Memo and more.
11. Game Launcher
The Galaxy S7 and S7 edge are gamer-friendly devices, and both come with an app that makes gaming even better. Game Launcher lets you maximize your game-playing time through a variety of power-saving options. You can also turn off all notifications so nothing interrupts your gaming and lock the Recent and Back keys to prevent accidentally exiting a game. In addition, you can also take screen shots, record games and share them with friends.

12. Smart Switch
Smart Switch, which makes it easy to transfer your old data to a new Galaxy device, has gotten an upgrade for the Galaxy S7 and S7 edge, with a new home layout, better app data recovery, and other improvements.

Allowing transfers from devices with different operating systems, Smart Switch is a convenient way to move all your files, including contacts, chat messages, photos, calendar, apps and music.
How to Set Up: Settings > Backup and reset > Open Smart Switch
13. Quick Dial
Quick Dial makes calling your contacts faster and easier. Once enabled, you just need to give the home key a long press (even if the display is off), and then speak the name of the person you want to call. Quick Dial takes care of the rest. Also, the feature’s machine learning allows your device to become more familiar with your voice over time, thus increasing the device’s functionality as you use it more often.

This is a function only on the Galaxy S7 edge model. Just as People edge puts your most important contacts right into the curved edge screen for easy access, and Apps edge does the same for your favorite apps, Tasks edge lets you assign a shortcut for your most common tasks. Setting an alarm, composing a text message or creating an event can be assigned to the edge of the display, for fast, easy access.
