Common Samsung Galaxy S20 Problems and How to Fix Them

Even with the release of the Galaxy S21 range, the Samsung Galaxy S20, S20+, and S20 Ultra are three very powerful smartphones. They boast muscular processors, highly versatile cameras, and delicious screens. That said, even the most exceptional new releases come with a collection of bugs, issues, and problems. If you’re staring at your Galaxy S20, wishing it would function as it should, then continue reading as we explain simple fixes to some of the most common Galaxy S20 problems that you might experience with the lineup.

Issue: Galaxy S20 Plus is stuck in a random reboot loop

Some users on the Samsung Forums have reported their S20 Plus reboots randomly and seems to be stuck in some kind of loop. There have been reports of this happening for some users when they unplug wired headphones, while for others it seems to happen on a regular cycle every few minutes.

Solution

There are a few things to try if this is happening to your phone.

The first thing to do is check to ensure there are no new software updates to install. If you’re all up to date, you could check to see if an app is causing the issue, by booting your phone in safe mode. Here’s how to do that:

  1. Press and hold the Power button.
  2. Tap and hold Power Off.
  3. When you see the Reboot to Safe Mode prompt, tap OK.

You should then be able to see if the rebooting issue keeps occurring — if it does, that’s indicative of it being an issue with an app rather than a hardware issue. Once youve finished troubleshooting, here’s how to exit safe mode:

  1. Press and hold the Power button.
  2. Tap Restart.

It’s also possible to turn off safe mode by opening the notification panel and tapping the Safe Mode Enabled notification.

If this doesn’t work, it’s worth wiping the cache partition. Here’s how to do this:

  1. Press and hold the Volume Down and Power buttons together until the power options appear.
  2. Tap Power Off.
  3. Once your device has shut down completely, press and hold the Power and the Volume Up buttons until the Galaxy S20 logo appears.
  4. Release the keys and wait until you see the phone boot into recovery mode.
  5. Use the Volume Down button to highlight Wipe Cache Partition.
  6. Once highlighted, select the option with the Power button.
  7. Press the Volume Down button to select Yes, then hit the Power button again.
  8. Your phone will take a few seconds to wipe the cache partition.
  9. Once it’s done, hit the Power button to reboot your system.

You won’t lose any data or settings when wiping the cache partition.

If these steps don’t resolve the issue, it’s time to take your phone to your nearest Samsung or carrier store, or contact Samsung support.

Issue: Galaxy S20 Wi-Fi doesn’t work properly

Some users have complained that their S20 Ultra has Wi-Fi connectivity issues, often failing to download web pages and content even though the phone indicates that it’s connected to a Wi-Fi network. Updating to Android 11 appears to create this problem, while other users have noted it for the other phones in the S20 series.

Solution

One fix proposed in the Samsung Community forum is to go to Settings > Location > Google Location Accuracy Off. Taking this route can solve most occurrences of this issue, although your best bet is to check for a new software update and download/install it.

Also, one solution for a similar problem with the Galaxy 10e is to wipe the cache partition on your phone (our article on Android’s recovery mode explains how to do this). This may be worth trying if the two steps above don’t work. It’s also worth resetting your network settings by going to Settings > General Setting > Reset > Reset Network Settings.

Issue: Galaxy S20 Ultra screen displays a green tint

After Samsung’s April 2020 update, a few Galaxy S20 Ultra users pointed out that their screens display a green tint. One user posted a photo, revealing the severity of the issue. The green tint seems most prevalent when the display’s refresh rate is at 120Hz and brightness drops below 30%.

Solution

Samsung’s firmware update (version G98xBXXU1ATD3) should now have been rolled out to affected devices and should solve the issue. If you’re still experiencing issues, limiting your screen’s refresh rate to 60Hz may help as a temporary fix, but you’ll need to contact Samsung or visit your local store for support. Here’s how to limit your refresh rate:

  1. Open the Settings app on your device.
  2. Scroll down to Display.
  3. Select Motion Smoothness.
  4. Select the lower 60Hz Refresh Rate.
  5. Tap Apply.

  2. Scroll down to Biometrics and security
  3. Select Fingerprints

All of Samsung’s latest smartphone sport larger batteries than ever before, but with new features on board, it can seem as though their juices are draining just as fast. Some users have reported poor battery life following a recent update. It doesn’t look as if Samsung has addressed this concern yet, but there are a few things you can try to solve the issue.

Solution

Check the status of your battery by heading to the Battery Usage graph located in the Settings app under Device Maintenance, then the Battery option.

  3. Select Motion Smoothness
  4. Select the lower 60Hz Refresh Rate
  5. Tap Apply

If this doesn’t seem to make any difference to battery life, you might want to try a factory reset. Don’t forget to make sure all your data is fully backed up before performing a factory reset, as all your data will be wiped from your phone.
