Like most smartphones, certain problems can be solved quickly by installing a new software update (if any). You can also try to perform a factory reset, but this should only be tried once you have completed all the other possible solutions.

Samsung Galaxy Note 20 Ultra not connecting to network properly

In addition to the few people who reported that their Note 20 Ultra has problems with the mobile network connection. In most cases, users fail to receive any type of mobile network signal, even if others report having a one-time connection but discarding it.

Possible solutions:

• Try restarting the phone. This has worked for some users.
• Try turning off Wi-Fi Calling off you have this setting switched on. Go to Phone > More > Settings > Wi-Fi Calling.
• Clear your Note 20 Ultra’s cache. You can do this by booting up your phone in recovery mode.
• If possible, try a different SIM card and/or network on your phone. This may help determine whether you have a phone or network issue on your hands.
• Switch from 5G to 4G. Go to Settings > Connections > Mobile Networks > Network Mode > 4G/3G/2G (Auto Connect).
• Reset the Access Point Names for your network. Go to Settings > Connections > Mobile Networks > Access Point Names > More > Reset to Default.

Galaxy Note 20 and Note 20 Ultra overheating problems

This is a problem that tends to be the most common touch on all smartphones, but it looks like the most common touch with the Note 20 Ultra, if due to its high output.

Excessive heat especially seems to be a problem when using the Camera app, where users complain that using the camera for more than a few minutes can increase the phone’s temperature.

Possible solutions:

• Avoid overusing the phone in high temperatures and/or direct sunlight. This can really incite any tendencies it may have to overheat.
• Do not film video in 8Kor 4K for too long. Take breaks if you need to shoot longer stretches of 8K/4K footage, or try filming only in 1080p.
• Erase battery-draining apps from your Note 20 (Ultra). This includes apps that promise to enhance performance or battery life, as well as apps that tend to run in the background. Social media apps (Facebook, Snapchat, Twitter, Tinder) are often big offenders in this respect, so get rid of any you no longer use.
• Try clearing the cache for any app you believe may be causing the overheating. To do this, go to Settings > Apps > [App] > Storage > Clear Cache.
• Some users recommend wiping your phone’s system cache (via recovery mode) or even performing a factory reset if the problem doesn’t resolve itself. However, make sure you back up your phone before performing a factory reset.

Faster battery draining on Galaxy Note 20 problems

Given that they can operate at such high speeds, it is perhaps not surprising to hear that some users have complained about their fast-charging batteries.

Some people have reported that their Note 20 battery lasts overnight, while others have noticed that they encountered a problem after upgrading to Android 11.

Workarounds:

• Wipe the phone’s cache partition via recovery mode. Switch off the phone, then press and hold the Power and Volume Up buttons. Release them when you see the Samsung logo. Then use the volume buttons to scroll through the options until you reach Wipe Cache Partition, which you can select by pressing the Power button.
• Try resetting your app preferences. Go to Settings > Apps > More > Reset App Preferences.
• Disable scanning for Wi-Fi and Bluetooth. Go to Settings > Location > Improve Accuracy > Disable Wi-Fi Scanning. Then select Disable Wi-Fi Scanning.
• Switch off background data and activity for less-important apps. You can do this by going to Settings > Apps > [App] > Mobile Data > Allow Background Data Usage > Off. Then do the same again, but after picking an app, go to Battery > Allow Background Activity > Off.
• Try turning on adaptive brightness for your display. Go to Settings > Display > Adaptive Brightness.
• It’s also worth turning on battery optimization. You can do this by going to Settings > Device Care > Battery > Power Mode > Optimized. Also activate Adaptive Power Saving on the same screen.

It almost means nothing, but if you continue to experience problems after trying these steps, you should contact Samsung.
