Dear Samsung Member,

Greetings from Samsung Customer Support!

As per your concern, we would request you to kindly perform the following steps to resolve your issue.

Galaxy device lag issue:
Check space availability
Kindly check the space on your device:
Path: Settings > Battery and device Care > Storage
To improve the device performance there should be sufficient space.

Kindly check the RAM in your device:
Path: Settings > Battery and device Care > Memory
The device's RAM should be free to improve performance. So clear the RAM memory once a day

Clear app cache through Device care:
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.

The clear cache memory of a particular application:
Settings > Apps > Now pick the app that you like to clear off the cache memory > Storage > Clear Cache.

Close Background Apps: Too many applications running in the background may cause the device to hang. Kindly close the background running applications on the device.

Kindly uninstall that application by following the below steps and check once as the issue might occur due to third-party applications: Settings> Apps> third-party application from Apps> Uninstall.

if you are using a memory card, we would like to inform you memory card device performance will be slow, so if you are using the memory card in your device. I will advise you to safely remove it from your device. For this follow the below steps:

Step 1: 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.
Step 3: Remove the memory card.
Step 4: 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.

Kindly remove third-party accessories( Not provided by Samsung) Accessories, (Like a charger, USB Cables'' etc.) devices might also hang.

"Power saving mode'' limits the performance of the device. So we recommend disabling the Power Saving mode in your device.

Galaxy device battery drain issue:
Charge in one go instead of charging many times as it affects the life span of the battery and battery performance

Perform Battery Optimization
Battery optimization helps you to boost the battery performance of your device. To check battery optimization:
Settings > Select Device Maintenance/Device Care/Battery and device care > Optimize > Optimize all options like Battery, Storage, and Memory

Turn off Wi-Fi, GPS, Bluetooth, etc.
Turn off unused functions like Wi-Fi, GPS, Bluetooth, and location settings when not using them: On the home screen swipe down the notification panel > Turn off Wi-Fi, GPS, Bluetooth, and other connectivity features when not using them.

Check device network fluctuation
Kindly check whether the mobile network fluctuates frequently or if the network signal is low in your area. In both cases, the battery will drain considerably fast.
Recommendation: We recommend you avoid using it in areas with low network/fluctuation.

Reduce display brightness level
Kindly set the device display brightness in auto mode (If available).
Adjust screen timeout settings: Settings > Display > Screen timeout > Select minimum screen timeout.

Check and update the App: Kindly check which application or interface is using more battery from device care. And try to update the app or avoid using that app.

Close background running apps
Close all the background running apps when not using them,

Turn off auto sync of e-mails, app data, etc.
We request you turn off the auto sync option, it will stop the synchronization of the device with the server & reduce the battery drainage.
The steps to turn off auto sync are:
1. Swipe down on the home screen to open the notification panel.
2. Turn off the auto sync option.
