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.

Samsung Galaxy S25 Ultra can boost camera features with variable aperture, if it actually happens
Samsung has a tonne of upgrades for the Galaxy S25 Ultra including a high pixel sensor and better videography capabilities but the flagship could get even more interesting if it equips a variable aperture camera system.
Samsung uses high-quality main lenses with the S series including the latest 200Mp module. The company has utilized this lens for Galaxy S23 Ultra and S24 Ultra, and it will likely come with Galaxy S25 Ultra.
Instead of the exact same module, the Galaxy S25 Ultra will get some photography and videography upgrades via new algorithms. Besides, you can have new camera app experiences thanks to the One UI 7.
So, it would be a mixed camera upgrade for the main lens. However, you can anticipate improvements in telephoto or ultra-wide angle to get some new improvements.
But what if Samsung adds a variable aperture to this new flagship device? That would be a key highlight for all photography enthusiasts.
Variable aperture enables you to change the aperture size by controlling the amount of light entering the camera.
In the background, the mechanism uses physical hardware that collaborates and changes the apertures using blades with opening and closing sequences.
It offers numerous advantages over a fixed aperture camera including:
- Low-light control – A large aperture can enter more light into the sensor to brighten the scene and reduce noise in low-light conditions.
- Depth Control – The aperture also controls depth of field, a large aperture creates a shallow depth to isolate a subject from the background. On the other hand, a smaller aperture creates a depth of field for landscape photography.

Galaxy S9 – The start and evolution
Variable aperture is not new to the smartphone industry, in fact, it has been available for years. Interestingly, Samsung was the first to popularize variable aperture with the Galaxy S9 in 2018.
The Galaxy S9 and S9+ feature dual aperture, which automatically adjusts and passes light to the sensor. It can switch between F1.5 and F2.5 for dark and light photography environments respectively.
Unfortunately, the Korean tech giant dropped this tech with the Galaxy S10 and went back to fixed aperture. So, Samsung is familiar with this tech but it will require some new advancement step ahead in the competition.
Chinese phone makers including Huawei and Xiaomi have led this tech to a new level in recent flagship devices. A more sophisticated multi-blade aperture system has evolved including the 6-blade architecture.
This offers better light control, quality, and depth of field than ever before. These and other smartphone companies are searching for new variable architecture to improve the overall design and quickness of closing and opening the blades.
Even some reports suggest that Apple could also adopt variable aperture for its upcoming iPhone 17 in 2025.
Why it should
Compared to its competitors, Samsung uses the top-of-the-line 200mp camera system and due to the sheer pixel density, It can experiment with these aperture sizes to bring the best for consumers.
Note: Samsung has not confirmed the variable aperture camera for the Galaxy S25 Ultra. So, we can only remain optimistic about the photography enhancements with this upcoming flagship.
Galaxy S26 Ultra?
If it doesn’t happen with the Galaxy S25 Ultra, we’ll have to wait for Samsung’s next S-series flagship – S26 Ultra in 2026. Yet, things remained unconfirmed from this point of view.
