Although Samsung has a reputation for making reliable phones that customers love – even to the point of being considered the best Android phone brand for customer satisfaction – a few odd software glitches and hardware constraints can still cause issues.
For example, Samsung phones have become infamous for their dead batteries after major updates. Some of these issues require the manufacturer to apply patches or perform proper optimization, so you can’t necessarily fix them yourself. Other quirks, such as the moisture-detection notification on older devices, may benefit from a few workarounds. If you find new issues, please use the Samsung Members app to report them so Samsung can collect data and provide advice when appropriate.
Battery exhausted after an update.
Users recommend waiting a week to see if the battery drain persists, as this gives your phone enough time to repair itself. But as a safety precaution, it is recommended to be careful with third-party apps, as they are not always as well optimized or compatible with new software, which can cause your device to drain faster than it should. The best solution is to use these apps sparingly to reduce their background activity.
Humidity detected error persists.
This is one of the reported issues that has caused phones to fail to charge, and sometimes this alert still doesn’t go away after hours of drying – although this is usually not the case. If the notification persists and you think your port is dry, start by carefully examining the opening with a flashlight to make sure no water remains.
If you’re sure it’s a software issue, restarting your phone may fix the problem. If this fails, deactivate the fast charging option under Settings > Battery > Charging Settings > Fast Charge. Another method is to try clearing the phone’s USB settings cache by going to Settings > Applications > USB Settings > Clear Cache. If the USBSettings application does not appear, make sure Show system apps is activated under the Filter and sort options (the three horizontal lines with a down arrow) in the main list of applications. If none of this works, you may need to replace your charger and ensure you are not charging your device in a humid environment.
Inconsistent animations in One UI
For the Good Lock theme issue, try removing the custom theme and using a default option to see if the animation issues are resolved. Also check if any modules need to be updated. Samsung often offers a new Good Lock update to devices that have recently received a new version of One UI, as operating system updates may cause compatibility issues with some Good Lock modules.
Finally, it can sometimes be helpful to adjust the animation scales on your Samsung phone. To do this, you will need to activate the hidden “Developer Options” menu by going to Settings > About phone > Software information, then pressing the Build number seven times in a row. Once enabled, select Developer options at the very bottom of your Settings app, then adjust the Window Animation Scale, Transition Animation Scale, and Facilitator Duration Scale choices. You’ll probably want to choose a lower value here. For example, if your default is 1x, change it to 0.5x.
The dreaded green line problem
You might see this on older phones like the Galaxy S20 series or even older generations of Z Fold and Z Flip devices. Unfortunately, the main long-term solution is to replace faulty hardware. Your best option is to contact Samsung to request a screen repair. Although India is the main region where Samsung has shown a willingness to repair devices outside warranty periods, you should always check whether the company is willing to repair your affected device in your region.
