How Do I Fix Dropped Calls On Samsung Galaxy S8 And Galaxy S8+ Plus

Dropped calls are a serious issue. When you can’t use your phone to make a proper call without the signal dropping, you need to do something about it and you need to do it fast. Samsung Galaxy S8 and Galaxy S8+ Plus users complain about this quite often. Whether it’s every few days or almost daily, but on different contexts, it is a sign that something is wrong and you shouldn’t overlook it. From weak signal reception to a network configuration problem, a hardware issue (most likely the antenna) or a software update problem, there are many things to blame.

At this stage, before taking it to an authorized service, you can try to observe and analyze the situation to the best you can. Maybe it will make you feel better or not, it’s not a Samsung specific issue, but rather something that many Android users experience. So here is what you need to take into account:


The top 3 troubleshooting options for the dropped calls issue on Samsung Galaxy S8 and Galaxy S8 Plus

Troubleshooting is all about finding the culprit. When you have found the root of the problem, you will be able to address it through a permanent fix and get rid of these annoying problems once and for all. As you are about to discover, there are three types of actions you can rely on when you’re dealing with such circumstances:

  1. You investigate on your own;
  2. You confront your service provider;
  3. You make some serious changes on your Samsung Galaxy S8 or Galaxy S8 Plus.


To investigate on your own, you will simply have to check the signal status as soon as the call dropped. Depending on how many signal bars you see, you might have to ask yourself a couple of other questions, but we’ll get there soon enough.

To have your service provider look into it, you need to make a phone call to their customer support right away. Again, questions are involved, only that, this time, the provider is the one to answer, not you.

As for the final option, be prepared to wipe the system cache and, if it won’t fix the problem, perform a master reset of Samsung Galaxy S8 or Samsung Galaxy S8 Plus.



Call your service provider

As suggested, when you cannot find a solution on your own, it will help calling someone entitled to give such answers. Gather as many details as you can and communicate them to the service provider. While on the phone with a customer support representative, ask:

  1. About possible upgrades or downtimes in your area
  2. About your account status
  3. About any settings that you might have to adjust


If it wasn’t any downtime reported at the approximate time of your drop call issue, you should insist on describing what and how happened – where were you, how long did you maintain the call before it dropped, if you’ve heard any kind of strange noises, and anything else you find relevant. Of course, there are outages that happen without being scheduled, in which case the agent won’t be able to tell you anything about it if they haven’t fixed the problem yet, but it is always worth asking.

The next problem you need to address is your account status. Is it in good standing, are you still enjoying their full services, is there any invoice issue flagged on your account? If this isn’t the case either, the last thing you can try on the phone is to ask details about the right network settings you should have on the Samsung Galaxy S8 or Samsung Galaxy S8 Plus smartphone.

It could be that the provider operated some settings changes to improve its services but the changes didn’t produce over the air with your device and a manual adjustment will fix just that.


Check the signal, immediately

Can you tell that you are in an area with poor reception? Are you in an open space, outdoor, or in a closed area like a room or a larger building with thick walls and lots of glass? Is this the first time you’re dealing with a dropped call or it’s becoming more of a habit? Is it a recent habit or you’ve noticed the drops spread through a longer period of time?

All these questions and their answers will indicate you what you have to do next. Suffices to say that if it’s the first time it’s happening, you might want to make the call from outside of the building – signal drops are common in such enclosed spaces. If it’s not the first time, continue to monitor the way that your Samsung Galaxy S8 or Samsung Galaxy S8+ Plus behaves, so you will know what to tell your service provider. Any kind of pattern or details about the context when the problem occurred might help you spot a solution sooner rather than later.


Take the problem in your own hands

If nothing worked so far, your service provider confirmed everything is ok with their services and your account, you’re in an area with clear signal but your calls are still dropping, you can suspect a software issue. To troubleshoot it, you can begin wiping the system cache and, if necessary, continue with a master reset.

The wipe system cache is a completely harmless action. Especially if you’ve noticed these issues after a recent update, you may be looking at some corrupt system caches. These files are essential for making a Samsung Galaxy S8 or Samsung Galaxy S8 Plus run smoothly. But they also rebuild on their own, so deleting them won’t be a problem at all.


To wipe the system cache…

  1. First, turn off the phone;
  2. Simultaneously press and hold the Volume Up, the Home, and the Power key;
  3. When you see the Samsung Galaxy S8 logo on the display, you can release only the Power key;
  4. Continue to hold the Volume Up and the Home keys;
  5. You can only release those two as soon as the Android Logo will appear on the screen;
  6. That’s the sign that you are entering the Recovery Mode;
  7. Wait for up to 60 seconds without doing anything;
  8. Then, start navigating around with the Volume Down key;
  9. When you have highlighted the menu entry labeled as “Wipe Cache Partition”, stop right there;
  10. Tap on the Power key once to press the option;
  11. You will see a window where you are asked to confirm the action;
  12. Use the same Volume Down key to select Yes;
  13. Use the Power key again to start the wiping process;
  14. Wait for it to finish;
  15. Then, highlight the menu entry labeled as “Reboot system now”;
  16. Start it from the Power key;
  17. It will take longer than usual, but the Samsung Galaxy S8 or Samsung Galaxy S8+ Plus will eventually reboot in the normal running mode.


Test the quality of your voice calls and see if you’re still getting signal drops. If you do, the only thing left to do is that general reset. As opposed to the previous action, this one will delete everything from your phone. So, make sure you back up whatever you want to keep and only then proceed with the steps from below.


To perform a master reset on Samsung Galaxy S8/S8 Plus:

  1. Turn off the phone;
  2. Simultaneously press the Home and Volume Up keys, followed by the Power key – take as much time as you need, the command will be taken into account only when the third key will be pressed, so do not stress out on how long you’ve hold the other two keys, just follow the steps;
  3. Soon after that, the Samsung Galaxy S8 symbol will appear on the screen;
  4. Release the Power key and keep holding the other two;
  5. When you see the Android logo, release the other two keys as well;
  6. Let it sit around for 30 to 60 seconds – keep in mind that you should also see the message “installing system update”, on the screen, seconds before the Android logo display and the access to the Android system recovery menu;
  7. Now that you’re in, navigate around with the Volume Down and initiate commands with the Power key;
  8. Go to the Wipe Data / Factory Reset menu and select it;
  9. Select Yes – Delete All User Data option when prompted to confirm the reset;
  10. Wait until the phone finishes the master rest and reboots into the Recovery Mode;
  11. Navigate with the same two keys and select the “Reboot System Now” option;
  12. Just like after wiping the system cache, the reboot will take longer but will return you to the normal running mode.


The hard reset, if it solved you the signal drops, just proved that it was a firmware issue problem. In the unlikely event that your Samsung Galaxy S8 or Samsung Galaxy S8 Plus smartphone is still manifesting the same annoying problem, there’s nothing left to do other than to send it in for repair. An authorized technician is your last option.
