Kindly perform some quick troubleshooting steps to resolve the hang issue:
1. Check space availability: Kindly check the space on your device: Settings > device care >storage. To improve the device performance there should be sufficient space. Keep at least ''minimum of 20% internal memory free''.
2. Check internal memory space: Kindly check RAM in your device: Settings>device care>memory. To improve the performance RAM of the device should be free. So, clear the RAM memory once a day.
3. Check app cache: 1- Clear app cache through device care: Apps> settings> device care> storage> clean now. Note: To delete files or uninstall apps that you do not use anymore, select a category under USER DATA. Then, tick items to select and tap DELETE or UNINSTALL.
2- Clear cache memory of a particular application: App screen>settings>apps>pick the app that you like to clear off the cache memory. For example, 'Samsung internet'> storage> clear cache.
4. Close background running apps: When running multiple applications, the processor processes more tasks and as a result, additional heat is released from the device. This happens with most electronic devices (even computers/laptops), including the devices of other manufacturers. Close all applications, not in use.
5. Uninstall the unnecessary (3rd party application) apps: Too many apps installed on the device may cause the device heating issue. Uninstall the unnecessary apps if not using them. Path: Settings>>Apps>>Select the third-party application from Apps. Eg. DU Recorder>>Uninstall
6. If the issue has not been resolved then remove the memory card from the device: Step1: Before removing the memory card, first, unmount it for safe removal. On the home screen, tap apps > settings > device maintenance > storage > more option > storage settings > SD card > unmount. Insert the ejection pin into the hole on the tray to loosen the tray Note: Ensure that the ejection pin is perpendicular to the hole. Otherwise, the device may be damaged. Step2: Pull out the tray gently from the tray slot. Step3: Remove the memory card. Step4: Insert the tray back into the tray slot.
Note: Please ensure that the memory card is not removed while the device is transferring or accessing information. Doing so can cause data to be lost or corrupted or damage to the memory card or device. Samsung is not responsible for losses that result from the misuse of damaged memory cards, including the loss of data.
7. Disconnect third party accessories from the device: Due to ''3rd party'' (not provided by Samsung) accessories, (Like ''charger, USB cable'' etc.) device might also hang. So kindly avoid the usage of these 3rd party accessories.
8. Disable power saving mode: ''Power saving mode'' limits the performance of the device. So, we recommend disabling the power-saving mode in your device.
