Samsung Galaxy S8 problems and solutions

Update: Is your home button too sensitive?

A couple of months ago, the Samsung Galaxy S8 and S8+ were released with considerable fanfare by the Korean manufacturer. This is completely understandable, considering the trail of disaster that was left in the wake of the Note 7's fiery demise. The company is banking on its new flagship to help it turn its fortunes around, but like a lot of new smart devices it's not without its issues. 

There are 10 sorts of people: those who understand binary and those who don’t.

Samsung Galaxy S8 audio problems

Users in Samsung's Community Forum have recently been reporting that they are having audio issues with their Galaxy S8 and Galaxy S8+ devices. Users state that the sound / audio of their S8 or S8+ cuts off at random when they are playing music, streaming YouTube videos or playing games. As far as we understand, this issue seems to only affect the sound coming out of the speakers, not the audio from the headphones. Users are speculating that the audio issues are due to loose wiring, a theory backed up by the fact that if you apply some pressure just above the speakers, the audio comes back on. Apparently, if you violently shake the S8 reproduces the same problem. If this is true, then it would definitely point to a hardware issue - meaning a simple software update won't fix the audio issue on the Galaxy S8.

So is there a solution to fix the Galaxy S8 audio issues?

Samsung has responded to some users that it could be an app or a software that's causing the issues and recommended them to put their devices in safe mode for 1-2 hours and monitor the audio usage. This apparently did not fix the problem though. 

Another user pointed out that both the Galaxy S7 and Galaxy S7 Edge had similar issues with the audio cutting out and recommended the following solution:

Enable the developer options on your Galaxy S8 if you haven't already done so. Go into the Developer Options -> scroll down to Media -> and toggle Prevent USB audio routing on. This apparently solved the audio issue on the Galaxy S7 and might prove to work for the S8 and S8+ as well.

If you want to test the speakers of the Galaxy S8 and S8+ in a safe menu, go into your phone's dialer and type *#0*#

Samsung Galaxy S8 rebooting issue

Over the past few weeks, a number of users have been reporting on the Samsung Community forum that their Galaxy S8 and S8+ devices keep on restarting. One quick fix is to do a factory reset, but the problem appears to resurface after a few hours. A few users have reportedly tried rebooting to resolve this issue, but discovered that after this their phones will not turn back on again at all.

There hasn't been any official confirmation from the company on this issue, but the indicators are that this could be related to the microSD card. Some users have reported seeing a “Transfer files to SD card” notification after restarting the phone, whereas others have said they are experiencing even more problems after they transferred or removed all the apps from the card.

Samsung has reportedly advised any affected customers to send in their devices for repair, exchange or for a full refund. That said, to date there has been no official statement from the company on this issue. This is a problem that they will ultimately need to respond to, as this is a significant fault: constant restarting on any smartphone will eventually make the device completely useless. Hopefully, all that will be needed is a software update to resolve this fault, but in the absence of any word from Samsung it might be time for us to prepare for the worst. 

Samsung Galaxy S8 display problems

One of the major selling points for both the Galaxy S8 and S8+ is their super AMOLED displays, which gives both devices very accurate color representations. It was also here that Samsung had its first reported issues with the S8 and S8+, as numerous users reported via Reddit that there was "bleeding" on the display resulting in discolored, red-tinted screens.

According to one Reddit user, this issue is nothing more than a limitation with Samsung’s OLED panels. To get even more technical, this is the result of Samsung's use of low-temperature polycrystalline silicon instead of a material like indium gallium zinc oxide.

Samsung has already responded to this issue by distributing a software update, which regulates the color balance of the device. The company says it is simply offering "a further enhanced ability to adjust the color setting to their preference," so once you receive the update you can adjust the display even more than when you first took it out of the box. Whether or not this actually goes someway to resolving the issue remains to be seen. We haven't had a chance to test these ourselves yet, but as soon as we have we'll let you know if the update is the answer to your prayers or the thing of nightmares. Keep watching this space. 

Samsung Galaxy S8 home button issues

Quite a few Galaxy S8 owners have recently been voicing complaints that their home button seems to be malfunctioning. After locking the phone it begins to vibrate and turns the screen back on, prompting a password unlock (either passcode or fingerprint scan). Apparently this issue occurs both immediately after locking the phone, as well as occurring after a delay of a few seconds.

Users in the XDA forum have discussed the issue, and it appears even when apps are disabled in accessibility and when the passcode options has been removed. It seems like the problem is related to the sensitivity settings of the home button. The Galaxy S8 doesn't have a physical home button anymore, so it could very well be somethings that's fixed by a simple software update. It's worth noting that at present the home button issue seems to only be occuring on Galaxy S8 devices.

Samsung Galaxy S8 Wi-Fi disconnecting and reconnecting

Quite a few users have been reporting that the Wifi connection of the Galaxy S8 keeps on dropping.  It had been suggested to try out different Wifi frequencies but the problem persisted with both 2.4ghz and 5ghz signals.

Wifi signals disconnecting and reconnecting were also an issue reported by Galaxy S7 users, many of whom had suggested clearing the cache (and some even recommended a hard reset). Clearing the cache worked for some users, but not all.

The Wifi issue has been acknowledged by Samsung / various carries, and a patch is in progress. If you own an unlocked Samsung Galaxy S8, you will receive the patch directly from Samsung. Otherwise you'll have to wait for your carrier to push out the patch for the Wifi problem.  

Samsung Galaxy S8 bluetooth connection issues

Apparently multiple Galaxy S8 and Galaxy S8+ users are having issues with their bluetooth connection. When the device is connected to bluetooth speakers and headsets, the audio breaks up. Other users are reporting that when they are listening to music via bluetooth speakers, the bluetooth connections just disconnects.

Samsung has acknowledged the bluetooth issues with the S8 and S8+ and had rolled out a patch in the United Arab Emirates first (most likely as a test) and is now planning on rolling out the bluetooth fix globally. If you have an unlocked device, you will receive the OTA directly from samsung, while branded devices will get the fix through their carriers.

Samsung Galaxy S8 fingerprint scanner not sensing finger

The Galaxy S8 fingerprint scanner seems to be causing several issues. The main problem at the moment seems to be that the fingerprint scanner can't or won't always recognize notification gestures or fingerprints. Some users report that the fingerprint sensor was basically acting dead, refusing to recognize multiple saved fingerprints to unlock the S8.

A temporary fix to this seems to be performing a simple reboot, though it's been reported that the issue of the fingerprint scanner not working comes up again. Users in the Samsung forum have stated that they spoke to Samsung support who said this was a software, rather than a hardware issue which should be fixed in an upcoming update.

Samsung Galaxy S8 face detection not working

Both Galaxy S8 and S8+ users have reported that after receiving an update in late April, the face detection has stopped working. Regardless how often a face is registered, the face detection refuses to work. The usual recommendations were made - clearing cache, rebooting, and making sure that all apps are up to date, though none of them had fixed the issue.

Samsung hasn't made any statements regarding the broken face detection, but it clearly seems to be a software issue.

Samsung Galaxy S8 Edge Lighting not working

There seem to be various issues surrounding the Edge Lighting not working.  In theory, Edge Lightning should light up the edge of the screen when a message or call is received. You should also be able to color code up to five contacts. Some users have reported that the edge lightning doesn't work with any app or call, and that it's not possible to assign colors to contacts. While many seem to think that this might have been a single carrier issue, users across the carrier spectrum have corroborated similar issues.  It seems like there could also be an issue that edge lightning only works with the Samsung Messaging app and not the one that your carrier provides - though this is still unconfirmed.

The first solution would be to go to Settings > Display > Edge screen, then tap and hold down on "Edge Lighting" (make sure that it's set to "Always on") and then tap on "Manage notifications." The notifications are turned off by default so you will need to turn them on individually.

Another issue that users have reported is that Edge Lighting works when the display is turned on, but refuses to work when it's turned off.

A possible solution here is to simply switch off the "keep screen turned off" in the display settings. To do this go into the Settings > Display and then scroll down to "Keep screen turned off" and toggle it off.

This doesn't seem to fix the issue for everyone one and, according to the Samsung forum, the company is currently looking into this issue.

A useful reminder is that for the Edge Lighting feature to work, your phone needs to be laying face down on the surface.

Samsung Pay freezing phone

Samsung Pay apparently has a bug which causes it to freeze up your phone. This issue seems to mostly occur when you try to "swipe to unlock" the display, and Samsung Pay then attempts to show your "preferred card." This then causes the phone to freeze up between both actions. Either your are then forced to wait until the phone figures out what it wants to do, or soft reset it.  

Uninstalling and reinstalling Samsung Pay doesn't fix this issue. The root of the problem seems to be that Samsung Pay incorrectly registers the swipe to unlock gesture, which then causes the mix up. Several users in the Samsung forum reported that removing/not having the favorite card selected seems to fix the issues, though it limited the usefulness of the Samsung Pay app.

Samsung Galaxy S8 infinity wallpaper not working

If you're having with the infinity wallpaper not working on your home screen, lock screen and always on display, it seems like there's an easy solution.

Go into Settings > Lock screen and security and then tap on the "Always on" display. You'll need to select the clock format that you want, which then brings you into a new menu where you can change the clock style, color and background. Tap on "Background" and make sure to select "None." This should enable the infinity wallpaper to work on all your display settings.

My Knox not working the Samsung Galaxy S8

Several users have tried downloading the My Knox app on the Galaxy S8 only to receive the message that the app isn't compatible with their phone.

The answer to this dilemma is that as of 2017, My Knox won't be compatible with Samsung Galaxy phones and will be replaced with Secure Folder.

Samsung Galaxy S8 wireless charging paused

Both Samsung Galaxy S8 and S8+ users have reported that they are encountering instances that when they are attempting to wirelessly charge, all they get is a blinking "charging paused".  Users are also complaining that docks and pads which they bought in combination with their Galaxy S6 and S7 devices don't work for the Galaxy S8.

While the cable itself doesn't seem to make any difference for the pad, it seems like the power brick (the thing that goes into the electrical outlet) seems to be the culprit. Users in Samsung forum have explained which combinations worked for them, and it seems like there's no clear pattern - just the fact that some power bricks will power wireless charging pads and fast charge in samsung docking stations and others won't.

The only real solution at this time seems to be that you should only use wireless charging pads and docks that are explicitly marketed for the Galaxy S8.

"The iris sensor is not responding. Try again later"

Multiple reports have surfaced up in various forums that the iris sensor of both the Galaxy S8 and Galaxy S8+ is throwing up an error. It seems to crop up most frequently when trying to unlock the phone, using Samsung Pay or Secure Folder. In those instances it produces the error message "The iris sensor is not responding. Try again later".

Samsung is aware of the issue, but no patch or fix has surfaced yet. Users report that restarting seems to be the only solution to temporarily fix this issue, though the problem will resurface hour later again.

Text message sound notification not working on the Samsung Galaxy S8 and S8+

Are you not receiving sound notifications when you get a text message? The easiest solution is as follows:

Go to Settings > Apps > Messages > Notifications and then make sure that this is set to "Allowed." None of the other notification settings work if this isn't set properly. If this does not fix the issue, make sure to backup your data and perform a hard reset.

  • I don't have an "audio" issue. My phone will simply just pause while any media is playing. Be it music, video, youtube, or anything else. It gets frustrating when you're working out and having to stop because your phone paused your music.

  • One last point, the Samsung Cloud Sync.

    It has synced and so I found out, removed hundreds of photos and videos to the Samsung cloud even though they are displayed in Gallery. They are not physically on the phone and my attempts to download them to my phone then transfer them to a SD card are blocked. I have not yet found out how to get these photos back physically onto my phone to enable me to back them up. Switching off the Cloud Sync blocks my access to the images totally. I cannot find how to access these online either to be able to download them and keep them in my own backup system.

  • Upgraded to the Galaxy S8 but extremely frustrated with it. The predictive text, especially using the swyping feature has been getting steadily worse since the S2 and Note4 where it was 90% perfect. The S6 used to come up with strange words on Swyping the keyboard but if you manually entered the word in using the keyboard it would accept and learn it.

    Now with the S8 it is driving me crazy as it often ignores what you manually type in and replaces it with very strange alternatives at random and more often than not you cannot remove these suggested option as you did previously.
    When using swyping feature it is even more irritating as it enters multiple words when you were swyping something simple like "and" is replaced with "as BF.". There are numerous times it replaces words with a "suggested word (space) then V8" even though your fingers were nowhere near these letters.

    The algorithms used in the S2 and Note 4 were perfect compared to this latest offering. Switching off predictive text also does not help as it will replace what you manually type with what it thinks you were typing

  • I love my S8+ but for the last 2 days on the right side of the edge I cannot get it to work easily. I have to touch multiple times... at times 10 plus. Can i please get some kind of idea of what to do?

  • Is there a simple way to delete apps and/or ringtones?

  • I can't send or receive text messages unless they are extremely short, like one sentence. Tried to send a picture and that failed too.

  • I have as Galaxy S8+. It was working fine now it says Downloading Do not turn off Target. Any ideas?? It will not turn off.

  • The Samsung 5 billion dollars in advertising has done its job on everyone here.

  • Anyone wanting to change there notification bar colour,theres a solution from the Play Store,Download Status,then Grant All the Permissions then chose the Colour you want,its easy to set up,mines Black now instead of White and alot easier to see now,cheers You Tube for showing me this solution

  • Here is my list of issues I am having with my S8+


    ▪Random restarts
    ▪freezes/ require a long hold on power button
    ▪SD card
    ▪Apps Ghosting
    ▪Slow charge with original charger
    ▪Overheating on charger
    ▪Overheating while watching a movie
    ▪Pink hue on screen edges
    ▪Apps including Native apps force stopping
    ▪Screen scratches with minimal force
    ▪Touch screen delay (takes a few seconds before it recognizes the touch)

  • Just wish we could change the notification bar at the top to Black or any other colour,so when you pick the wallpaper you want you can see the notification bar more clearly,or even change the size of it as well,as white does match with every colour

  • My wifi says it's connected but it's not. I've restarted my router. I've deleted the wifi connection and connected it again. Just did a hard reset and cleared cache . It's still not working. I do not want to do a factory reset. Is there another way to fix this?

      seems like youll have to wait for a patch to come out then. Are you using an unbranded device? If not then it will have to come through your carrier

  • So Glad i got the Galaxy S8 Plus,and everyday keep checking you tube how to get the Best from the phone,Batterylife can be extended by using certain settings,just miss pressing the Home button to turn on the screen

    My Note 4 was just about done, it wouldn't have made it until the Note 8 comes out. Got the S8+ and have no issues,it's a great phone. When the Note 8 comes out, I'll give the S8+ to my wife and get the Note 8 for myself.
