Internet Speed Slow On Samsung Galaxy S8 And Galaxy S8 Plus (Solution)

Using apps like WhatsApp, Facebook, Twitter, Snapchat or YouTube is taking you ages? Your Samsung Galaxy S8 or Samsung Galaxy S8 Plus is a powerful enough device to spare you from such issues and still, here you are, looking for some internet slow speed tips and tricks.

We have a couple of solutions for you, but before we move on to that part, let us mention some potential causes. Many of our readers have come to fix this problem without having to deal with the more serious troubleshooting options, just by looking into the following list.


Most common slow internet speed causes on Galaxy S8 and Galaxy S8 Plus:

  • Signal strength – low, poor, call it anyway but unless you have the appropriate signal strength, you can’t have a decent navigational experience;
  • Wi-Fi network – if it’s a poor wireless network you are connected to, again, the result might be frustrating, so, try another one if you have the chance;
  • The website is dealing with a traffic spike and its resources are exceeded – trying to access that website on different moments in time could give you better clues if that’s the case;
  • The network itself may suffer a congestion – you can test if the number of network users is to blame by connecting to another network or by connecting at different times of the day or night;
  • Too many apps are running in the background of your smartphone – turn off the recently opened apps and see how it goes;
  • The device memory is too low – clear up some space and see if there’s any change;
  • The internet cache is full or corrupted – clear the cache of the internet browsing app and the speed might improve;
  • You’re using an outdated firmware version – if you have blocked your smartphone from manually updating the OS, check for the latest firmware and install it as soon as possible;
  • The internet browser has an outdated software – check the Play Store to see if there’s any new update available for it;
  • The Samsung Galaxy S8 / S8 Plus has reached or exceeded the data speed limit – check your mobile data settings or switch from mobile data to Wi-Fi and notice the differences.
