How to Fix Common Samsung Galaxy Note 20 and Note 20 Ultra Issues
The Samsung Galaxy Note 20 and Note 20 Ultra are two of the best Android smartphones you can buy right now. They feature powerful processors, versatile cameras, huge batteries, beautiful screens, and excellent overall performance. Of course, technology being what it is, they can run into trouble sporadically. We've looked at the most common issues with the Samsung Galaxy Note 20 and Note 20 Ultra, explaining why they're likely to arise and defining what exactly you need to do to resolve them.
As with most smartphones, certain issues can be quickly resolved by installing a new software update (if one is available). As a last resort, you can also try performing a factory reset, but this should only be attempted if you have exhausted all other possible solutions.
Samsung Galaxy Note 20 Ultra is not connecting to the network correctly
Possible Solution to This Problem
- Try restarting your phone. This worked for some users.
- Try turning off Wi-Fi calling if you have this setting turned on. Go to Phone ⇒ More ⇒ Settings ⇒ Wi-Fi Call.
- Clear the Note 20 Ultra's cache. You can do this by booting your phone into recovery mode.
- If possible, try a different SIM card and/or network on your phone. This can help determine if 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 (automatic connection).
- Redefine the access point names for your network. Go to Settings ⇒ Connections ⇒ Mobile networks ⇒ Hotspot names ⇒ More ⇒ Reset to default.
Note 20 and Note 20 Ultra overheating
Possible Solution to This Problem
- Avoid excessive use of the phone in high temperatures and/or direct sunlight. This can really incite any overheating trend.
- Do not shoot 8K or 4K videos for a long time. Take breaks if you need to record longer stretches of 8K / 4K footage, or try shooting 1080p only.
- Delete battery-consuming apps from your Note 20 (Ultra). This includes apps that promise to improve 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 regard, so get rid of any that you no longer use.
- Try clearing the cache of any app that you believe is causing it to overheat. To do this, go to Settings ⇒ Applications ⇒ [App] ⇒ Storage ⇒ Clear Cache.
- Some users recommend clearing your phone's system cache (via recovery mode) or even doing a factory reset if the issue doesn't resolve. However, be sure to back up your phone before performing a factory reset.
Autofocus is not working properly
- Close and reopen the Camera app.
- Try clearing the Camera app cache. Go to Settings ⇒ Applications ⇒ Camera ⇒ Storage ⇒ Clear cache.
- Try switching to Video and then back to Photo. Some users report that autofocus is working again.
- If you are taking a close-up, try moving your phone away from the object. Try using the telephoto lens of the periscope at a distance if you want a close-up instead of the main wide-angle lens close to the subject.
- Some users have reported that shaking the Note 20 (Ultra) may initiate autofocus. If you try to do this, make sure you don't do it too vigorously.
- Try cleaning the lens with a microfiber cloth.
Battery draining quickly on Note 20 and Note Ultra
- Clear the phone's cache partition through recovery mode. Turn off your phone and hold down 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 the Clear 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 Wi-Fi and Bluetooth scanning. Go to Settings ⇒ Location ⇒ Improve accuracy ⇒ Disable Wi-Fi scanning. Then select Disable Wi-Fi scanning.
- Turn off background data and activities 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 choosing an app, go to Battery ⇒ Allow background activity ⇒ Off.
- Try turning on adaptive brightness for your screen. Go to Settings ⇒ Screen ⇒ 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, enable Adaptive Power Save on the same screen.
- Try to check your settings carefully for any other features that might be working in the background and that might be unnecessary. For example, certain apps check location data, which you can turn off by going to Settings ⇒ Privacy ⇒ Permissions Manager ⇒ Location.
Note 20 and 20 Ultra restarting randomly by itself
- Boot into Safe Mode (holding the Power button and then holding the Power Off button until the Safe Mode option appears). This restricts your phone to using only native apps, preventing downloaded third-party apps from affecting its operation. If you find that your phone does not randomly restart, this gives you an indication that a third-party application is causing the issue. So, delete all these apps and add the most important ones back one by one, making sure the phone works normally after each new addition. If it starts playing after you've added a particular app, delete it and keep it off your phone.
- Clear the Note 20 or Note 20 Ultra cache partition. You can do this by booting the phone into recovery mode by holding the Power and Volume Up buttons when the device is off. Then select Clear cache partition.
