15 common Galaxy S8 problems and how to fix them

The Samsung Galaxy S8 continues to be sold globally and users are starting to complain about Galaxy S8 problems. New problems emerge almost daily. With this in mind, below we provide a list of common problems you may encounter, along with methods to fix them. These solutions also work for Galaxy S8 Plus.

Samsung Galaxy S8 is available for sale in less than a month, which means that more problems will appear in the near future.
This is still a worthy replacement for the older Galaxy S7 and Galaxy S7 Edge, but there are some issues to consider. We will deal with the most important complaints and offer fixes and other ways to solve the problem.

reboot, Samsung

This is an impressive smartphone with a lot to offer its users. It has a stunning Infinity Edge screen with tiny bezels, tons of performance, and a great camera. But just like all flagship smartphones, it’s not perfect.

How to fix Galaxy S8 fingerprint scanner problems?
The first and biggest problem with the Galaxy S8 for most users is the location of the fingerprint scanner. It is located just awful. The scanner is located on the back of the smartphone, but not under the camera. To make matters worse, the Galaxy S8 and Galaxy S8 Plus are larger than most flagship smartphones, making the scanner beyond the reach of most users.

Unfortunately, there is no real way to fix this problem, owners just have to get used to the new position of the scanner. Muscle memory will force you to look for a Home button that no longer exists. The only real solution is to carefully tune the scanner, which will help to accurately read the fingerprint.

For example, after installing the cover, the scanner may not be able to read prints well. Delete the saved prints and re-set up with the case, be sure to follow the onscreen instructions during this process. Changing angles, finger directions, and other tweaks can give you better results.

The scanner is not a button, there is no characteristic click during scanning, so you never know if you hit the camera instead of the scanner. As a result, the camera lens quickly becomes stained.

How to fix a face and iris scanner?
Fortunately, Samsung provides several different biometric device unlocking methods to compensate for the poor placement of the fingerprint reader. You have access to the face recognition system and the Iris (iris) scanner, which we saw on the Galaxy Note 7.

The Iris scanner works at night, through glasses, and at larger angles than the Galaxy Note 7. However, in the comments, users claim that none of these methods work well enough. If you have any problems, we recommend that you delete your Iris scanner settings and re-configure it. Try to open your eyes wide the first time to provide a better reading.

With face recognition, things are even worse. Some users like the feature, while others find it useless and complain that face recognition doesn’t work. A photograph of your face can also trick the system. Therefore, be careful if this is your only method of unlocking your smartphone.

Instead of using your face, we recommend using a feature called Smart Lock. It uses GPS to keep safe locations, whether at home or work, and your voice and your Bluetooth accessories can also unlock the Galaxy S8 automatically. Thus, when you are at home, the smartphone is not blocked. One has only to leave the house, and the smartphone will be blocked. This solution allows you to interact with phone scanners as little as possible.

Go to Settings. Lock Screen & Security. Smart Lock and enable the function. Then adjust the location and connect the bluetooth devices for the best performance of the function.

How to fix not full screen Galaxy S8 apps?
Another big problem that we keep seeing complaints about is apps that don’t go full screen. With a large 5.8 “or 6.2” Quad HD display, some applications may not be able to use the entire space. This is due to an aspect ratio similar to that of a 16: 9 widescreen cinema that plots black bars. Fortunately, you can fix it quickly and easily.

Until now, most applications have worked fine and scaled, but some don’t. If so, follow these steps to fix this issue.

Pull down the notification panel and go to “Settings” (the gear icon in the upper right corner);
Find and select “Display / Screen”;
Select the “Full Screen Applications” option;
Find any application that is not highlighted and switch it to full screen mode;

The app will now automatically scale to the new 18.5: 9 aspect ratio and fill the entire screen. Some of them might not look right, but almost all of the apps we’ve seen displayed fine. Alternatively, owners can click the Recent button and click Expand (green icon) to instantly switch to full screen mode for that app. If necessary.

How to fix Wi-Fi problems Galaxy S8?
Countless reports confirm Wi-Fi issues on the Galaxy S8 and Galaxy S8 Plus. Owners mention poor connection performance, disconnections, and speed dips that prevent even the website from loading until the smartphone is disconnected from Wi-Fi. We see these problems with almost every smartphone that comes to market.

If you are experiencing Wi-Fi issues on your Galaxy S8, we recommend that you reset your home router or modem first. Better yet, reset your network settings to their defaults. We found that turning off the power to the router for 10 seconds or so and then restarting it will allow your smartphone to connect. Try going to Settings. Connections. Wi-Fi and reset your wireless network. Then reconnect, enter the password and reconnect.

If you used Samsung Smartswitch to transfer data from your old smartphone, the Wi-Fi information is also transferred and the new Galaxy S8 will connect automatically. If this is your case, we highly recommend reconfiguring your connection manually.

How to get the app drawer back on the Galaxy S8?
Not only are we missing a physical Home button like we’ve seen on all Samsung smartphones over the past seven years, but the Galaxy S8 lacks an app tray shortcut. How to find and open all your apps?

Instead of wasting home screen space with a dedicated white button, Samsung has created an app drawer gesture. Just swipe anywhere at the bottom of the screen to open the app drawer. This is a functional change at the phone software level.

You can remedy the situation, however. Pinch any free space on the screen. The desktop shrinks to indicate the transition to edit mode and page layout, as well as rearrangement of widgets and background image. Click on the “Settings” button (gear). Now go to the “Applications Button” option and select “Show Button”. Now accept the settings and go back. You will see a familiar button at the bottom of the screen, it will open the application tray.

Samsung has even added a “Home Screen Only” option if you want all your apps to stay on the home screens just like they do on the iPhone. Try this solution, you will be able to create folders to keep the interface clean.

How to fix red screen tint on Galaxy S8?
Some users, mainly from Korea, have outlined the problem of screen red tint, which distorts colors. This is not a hardware issue that will require a replacement phone, a software update should fix it.

As you can see above, two smartphones have a reddish tint, while one smartphone displays a normal white screen. This is a calibration problem in one form or another, since then Samsung has updated the phone software, offering users a large number of options to customize the screen to their liking. The update is already available in Russia for Galaxy S8 users.

How to change screen resolution on Galaxy S8?
Another problem is that the Samsung Galaxy S8 comes with a QHD screen (2960 x 1400). Higher than most Full HD (1080p) TVs. However, Samsung is downgrading the default resolution to 1080p for daily use. The manufacturer did the same with the Android 7 Nougat update for the Galaxy S7.

This solution, which is almost invisible to the user, however, improves smartphone performance and battery life. Most users won’t be able to tell the difference between QHD and Full HD (1080p) on a phone. However, if you want Quad HD that you paid for, the resolution is easy to change.

Just go to Settings. Display. Screen Resolution and slide the slider all the way to the right to WQHD for the best screen experience.

How to Fix Wet Speaker Problems on Galaxy S8?
Like its predecessors, the Galaxy S8 and S8 Plus are IP68 certified, meaning they are protected from water and dust. This means that you can lower your smartphone to a depth of two meters for a period of no more than 30 minutes. It’s protected from damage with no plugs covering the ports, no covers for you.

If the Galaxy S8 gets wet, the speakers may sound funny for a while, but water can’t do long-term damage to your smartphone’s sound.

Samsung uses a specialized coating on the inside of the speaker and on the surface to keep water out. If the speaker doesn’t work or doesn’t sound well after getting wet, just let it dry. There is a dedicated screen behind the speaker grill, but sometimes just a little water gets on the speaker.

Try shaking the phone, blowing lightly on the speaker grill, or blotting your side to catch any remaining water. After the speaker is dry, it will work normally.

How to fix Bluetooth problems on Galaxy S8?
Even though this is the first smartphone with Bluetooth 5.0 to cover four bands, quickly pair and connect two devices at the same time, we see tons of complaints about Bluetooth.

Several users point out that the Galaxy S8 does not even see its devices, which makes it impossible to connect them to a smartphone. Reminds of old CDs that sometimes could not be read. Sometimes a very bad connection becomes a problem. We see a flood of complaints on the Samsung forum, but no solution in sight.

One participant suggests turning off the Galaxy S8 and your Bluetooth accessory. Turn them back on, remove any link (pairing) and reconnect to your headphones, speaker, or car. Often, a simple reboot is enough to fix Bluetooth problems. Users can also head to Settings> Applications> Bluetooth Search and clear the cache. This solution will remove all mates, which helps some users.

If you continue to experience Bluetooth issues, you may have to wait for a software update.

How to fix Galaxy S8 camera problems?
Did you receive a “Warning, Camera Failure” notification on the Galaxy S8? Some users complain about this problem and then immediately close the camera application. So you cannot take pictures.

Like last year, the smartphone offers a feature called “Smart Stay” that can cause errors. It uses the device’s sensors to keep the screen on while you look at it. Unfortunately, this feature interferes with the camera again. Head to Settings. Advanced Features and disable Smart Stay.

We also faced this issue: Galaxy S8 camera app closes and displays a warning that the temperature is too high.

This is quite common in a hot car in the summer, but you shouldn’t have any problems when photographing indoors. This should not happen in other conditions. If you faced similar problems, write to us.

Another problem is Bixby Vision. An important selling point for the Galaxy S8 is the built-in assistant that also uses the camera to find information about the items you are shooting. For most, the function does not work at all or occasionally. We have deprecated this feature and hopefully an update will make the assistant more useful in the near future.

How to fix slow charging or wireless charging?
Samsung Galaxy S8 won’t explode? After the Note 7’s troubles, this issue has come up a lot. We cannot say 100%, but most likely the new flagship is perfectly safe. Samsung includes 8 battery test points and tests its phones extensively before release.

However, you may feel that the smartphone gets a little warm while charging. Other charging complaints include the Galaxy S8’s slow charging speed. I use a case so I don’t feel the warmth like others. If you are playing games or performing labor-intensive tasks, the smartphone may also become warm.

Alternatively, Galaxy S8 owners who are worried about the heat while charging can head to Settings> Battery and turn off the Fast Cable Charge option, which uses Quick Charge 2.0 and Samsung’s Adaptive Charging. This means that the smartphone will not charge from 0 to 50% in 25-30 minutes, and a full charge will take more than two hours, but it will not get too hot. If your smartphone charges too slowly, make sure you use a special adapter that comes with your smartphone and a high-quality USB Type-C.
Owners can’t just use a USB Type-C cable with an old charger as it doesn’t supply enough power to enable fast charging. Remember, if you need extra power, buy the matching accessories.

Speaking of charging, many reports have gone over fast wireless charging, which just doesn’t work for some users, even on Samsung‘s fast charging pad. We suspect the update will help fix this issue, perhaps Samsung is limiting fast charging functions for some charging panels in order to keep the temperature of the smartphone normal. We’ll update this section when we find out more.

How to reset a frozen Galaxy S8?
If your phone freezes, you can manually reboot. It will help you fix minor random phone issues. Whether it’s screen glitches or screen orientation errors, app stuck or other minor issues, a quick restart often solves them.

Owners can easily reboot their smartphone by long pressing the power button and then clicking “Restart”. The phone will shut down and restart, allowing you to work as intended.

We have prepared a separate article for a hard reset. Press and hold the Power and Volume Down buttons for about 7-8 seconds, until the Galaxy S8 vibrates and restarts. This will fix almost any minor Galaxy S8 issue.
Speaking of reboot, it looks like some users have encountered the problem of randomly rebooting the Galaxy S8. In case the smartphone simply restarts for no apparent reason. Based on over 100 comments on the Samsung forum, this is a fairly common problem. The company is aware of this, and some users say that ejecting the MicroSD fixes the situation. We recommend that you format the SD card and try again to see if the reboots have gone through or not.

The Galaxy S8 and the “DQA keeps stopping” message are another common issue that users have been complaining about. Unusual error that pops up on some devices. The problem can be resolved after a reboot. The culprit is the “device quality agent” service that scans Wi-Fi devices. Samsung has reportedly fixed this issue with an internal interface update using the Galaxy Apps Store. For some users, the update helped fix the error.

How to factory reset your Galaxy S8?
And last but not least, restore your phone to factory settings. It removes all user data, apps, messages, and other phone content. So use this solution as a last resort. If you’re having any major issues with your Galaxy S8, try a factory reset.

This is a good way to prepare your smartphone to install new software like the upcoming Android O update. Users can then take advantage of the SmartSwitch function to automatically restore device settings. Go to Settings. General Settings and click Reset.

The whole process will take a few minutes, restore the original software, like on a smartphone out of the box, deleting everything. Galaxy S8 owners can use Samsung SmartSwitch or Google Restore to get all apps and settings back. Again, this is the last resort.

, The Galaxy S8 remains a brand new smartphone, available on sale for less than a month. The more users buy it, the more new complaints we expect.

Supporting solutions

Things are much more serious when your favorite gadget does not fully respond to the power button. There is no universal recommendation for such a case. Representatives of manufacturers and service centers advise you to try one of the following ways to rescue a frozen phone:

  • Incoming call. you should ask someone to call the problem smartphone. If the display shows an incoming call, then you need to quickly call the restart menu by holding down the power button.

How to restart your Samsung Galaxy S8 phone if it freezes

Until a few years ago, almost all Android smartphones were equipped with collapsible cases. In the event of system failures, device owners could perform a quick reboot by removing the battery for a couple of seconds.

It will be easy to figure out how to restart a Samsung Galaxy S8 phone if it freezes. the developers of the popular operating system have provided several ways.

  • errors in the work of the graphical shell or when updating the OS;

  • mechanical damage.

In many situations, rebooting helps the smartphone to recover. If the freezes are permanent, then you will have to resort to more serious measures.

Startup problems

The next method is relevant for such a problem. the smartphone freezes when turned on. This manifests itself in the form of a loading screen, which does not disappear anywhere for too long. Usually, the device can be turned off by simply holding down the corresponding button. The situation can be resolved as follows:
