1 Common Issues And Error Messages
Common issues and error messages can be quite frustrating when it comes to troubleshooting Samsung Galaxy S21. Fortunately, there are several steps you can take to try and resolve the issue. First, check whether the problem is related to hardware or software by restarting your device. If that doesn’t work, try clearing the cache of any apps which may have been affected. Additionally, you should also check for updates in both the OS and any third-party apps installed on your device. This could help fix minor bugs and glitches that might otherwise cause problems with how certain features function. Lastly, if none of these solutions works, then contact customer service for further assistance.
2. Battery-Related Problems
Transitioning from the common issues and error messages, battery-related problems are another issue users could experience with their Samsung Galaxy S21. If your device is draining battery quickly or if it won’t charge at all, there are a few things you can do for troubleshooting Samsung Galaxy S21 battery issues. First, make sure you’re using an appropriate charger that meets the requirements of your phone model. Using chargers made for other devices may not be compatible and could damage your battery in the long run. Also, check to see if the charging port on your device is blocked by dirt, dust, or lint; this could interrupt current flow and prevent charging altogether.

If those steps don’t help, try restarting your phone while connected to its power source and then wait a few minutes before trying again. In some instances, rebooting can kickstart the process and let you get back up and running quickly. Alternatively, if these solutions don’t work out for you, consider taking a look at online forums or calling customer service for further assistance.
3. Connectivity Issues
- Check if your device is connected to the correct Wi-Fi network** – make sure that you’re not connected to an old or outdated network.
- Restart your phone** – sometimes this simple step works wonders in restoring connectivity.
- Reset the Network Settings** – this will reset all of your saved networks and you'll need to reconnect them again afterwards (make sure you have the passwords handy).
If these steps don’t help, it could be time to contact customer service for further assistance. They should be able to identify any underlying causes and guide you through resolving the issue quickly and efficiently.

4. Application Errors
Moving on from connectivity issues, application errors can be a source of frustration with the Samsung Galaxy S21. As with any device, software updates will sometimes fail to install or cause other problems with applications. Fortunately, there are several methods for troubleshooting Samsung Galaxy S21 app errors. The first step is to restart your phone and try reinstalling the problem app(s). If this does not work, clearing the cache data may help fix any corrupted files that could be causing an issue. It is also possible that certain apps might be incompatible with the operating system version you have installed on your device. In these cases, updating to the latest OS version available may resolve your issue. Additionally, some users find success by disabling battery optimization settings in their phone’s Settings menu. Doing so helps prevent apps from being forced into sleep mode when they’re not actively running in the foreground. Ultimately, if all else fails, it may be necessary to contact tech support for further assistance or consider resetting your device back to its factory defaults as a last resort measure.
5. Screen Glitches
If you have noticed screen glitches on your Samsung Galaxy S21, there are a few troubleshooting steps to try. First, make sure the device is updated with the latest software version. You can do this by going into Settings and selecting ‘Software Update’. If an update is available, it will be listed at the top of the page.

Next, check if clearing out any temporary files or caches helps resolve the issue. To do so, open Settings again and select ‘Device Care’ followed by ‘Storage’. There should be an option to clear up space – tap that and wait while your device clears all unnecessary data from its memory. A quick reboot afterwards could also help speed things up.
