Performing the following procedures will help eliminate common factors that might have hindered your phone from getting the right internet speed that you’re subscribed to. Try these before escalating the problem to your Internet service provider.

2. Check your signal strength

If you’re in an area with poor signal strength, your internet speeds will inevitably be slower. Make sure you’re in a spot with good reception before troubleshooting any further.

To check the signal strength on your Galaxy S21, follow these steps:

3. Disable Wi-Fi Assist (Intelligent Wi-Fi)

With Wi-Fi Assist disabled, your Galaxy S21 will no longer automatically switch to mobile data when Wi-Fi is weak or unavailable.

Note: Disabling Wi-Fi Assist may result in slower internet speeds when Wi-Fi is not available. However, it can also help to improve battery life and reduce data usage.

To clear the cache and cookies on your Samsung Galaxy S21, follow these steps:

  6. If you want to delete the data, too, tap on Clear data.
  7. Tap on OK to confirm.

Note: Clearing the cache will delete all temporary files that the app has stored on your phone. This can improve the app’s performance and free up storage space. Clearing the data will delete all of the app’s settings and stored information. This will reset the app to its factory defaults.

To clear the cache and cookies for all apps on your Galaxy S21, follow these steps:

6. Update your phone’s software

Samsung regularly releases software updates for the S21 that include bug fixes and performance improvements. Make sure you’re running the latest software version to rule out any known software issues that may be causing your internet to slow down.

To update software on the Galaxy S21, you can follow these steps:

Alternatively, you can check for available software updates manually by going to Settings > Software update > Check for software updates.

7. Contact your carrier

If you’ve tried all of the above and you’re still having problems, it’s possible that there’s an issue with your carrier’s network. Contact your carrier’s customer support team for assistance.

There are a few ways to contact your internet service provider (ISP):

  • Phone: Most ISPs have a customer service phone number that you can call to get help with your internet connection. You can usually find this number on your ISP’s website or on your monthly bill.
  • Live chat: Many ISPs also offer live chat support on their website. This can be a convenient way to get help if you don’t want to wait on hold on the phone.
  • Email: You can also contact your ISP by email. However, this may be the slowest way to get help, as ISPs may take several days to respond to emails.
  • Social media: Some ISPs also offer customer support through social media, such as Twitter and Facebook. You can send them a direct message or reach out publicly with your concern.

  • Disable any unnecessary apps that are running in the background.
  • Close any apps that are not in use.
  • Avoid streaming video or music while downloading files.
