The current flagship of the Samsung Galaxy line S3 features 4.8 inches of screen display with Super AMOLED capacitive touchscreen, TouchWiz UI, Corning Gorilla Glass 2, Android 4.0 Ice Cream Sandwich, 1GB of RAM, and 1.4GHz quad-core Cortex A9.
Samsung Android 4.1.2 XXBMA1 Jelly Bean firmware is available for Galaxy S3 LTE I9305.
While many users of this device love the 8MP rear-shooting camera featuring simultaneous HD video and image recording, high speed browsing, and possibly the smooth user interface, over time the device becomes laggy, drains battery quickly, and almost useless that owners want to replace it for another brand.
The problem with memory management is experienced not only by high-end devices but also with the low-level ones. A large display can mess up more with the memory because the bigger a widget is, the more processing and cache needs to keep it going smoothly. Many applications can also cause the device to go slow, and because Galaxy S3 has more storage for all possible apps found in Google Play, users tend to download apps they don't actually need and apps that contradict each other.
Here are some ways to keep that memory in check and help improve Galaxy S3's overall performance.
1. Check your storage availability or ROM, Go to Settings > Storage and if the storage space is running, try removing some files in the device - computers are still the best place where to store files. Too many files kept in the device slow overall performance.
2. Uninstall applications that are unnecessary and not frequently. Sometimes it is also advisable to remove newly installed applications. Developers can always create amazing applications, but poorly written applications can significantly affect your device. To do this, go to Settings > Applications, then choose the application you want to uninstall.
3. Applications may leave trails inside the device called cache which can also slowness. It is recommended to clear cache regularly. To do this, go to Settings > Applications and click the application frequently used and select Clear Cache.
4. Android devices virtually can keep unlimited number of text messages but too many SMS will lag the entire system at times. Thousands of messages can cause any messaging app including the stock messaging of Android to load slower, it is highly recommended to clear text messaging every now and then. Go to Messaging > Press Menu > Delete Threads. You may also perform this with other messaging app that can select which threads you want to keep. Another way to maintain the speed of your messaging is to limit how much text there should be per thread. Go to Messaging > Press Menu > Settings > Choose Limit, the same goes with other sms apps. If you want to keep records of your SMS, create a backup to your computer instead.
5. Just like computers and tablets, restarting your device is necessary. Restarting the device helps free memory and gives it a fresh start. Hold the Power key and select Restart. Fast reboot does not free up memory compared to the regular Restart or Reboot. Some users habitually restart their device as it recharges.
6. Live Wallpapers are beautiful and some of them can lag device due to high graphics or high memory demands. If you are experiencing any slowness, use Live Wallpapers that are light or simply enjoy a still wallpaper, less memory and less battery consumption.
7. For Internet connection, use Wi-Fi whenever available than data connection. Wi-Fi most likely supports higher connection speed for applications to update faster without eating much resources and energy of the device.
8. Close applications using the Back key instead of the Home key. Pressing the Home key inside an application puts it under Standby mode, consuming memory and battery. Alternatively, hold down the Home key and select the Task Manager. It will display running applications and option to end it. Other task manager apps are not recommended, use the one provided by Samsung.
9. Android OS always keep applications and performance in check, so never install applications which could interfere with the native OS. Third-party task manager and battery savers can later cause problems which they are trying to prevent.
10. As an additional option, you can clear the device temporarily files to free up memory. Turn off the device, press simultaneously the Volume Up, Home and Power keys. When the device vibrates, let go only the Power key and keep holding the other two. When the Android recovery appears, let go of all other keys. Navigate through the menu using the volume keys and use the power key to select a menu. Highlight the "Wipe Cache Partition" by using the volume key and then select it. After the process, the "Reboot Phone Now" will become highlighted, press the power key to select it and wait till the device reboots.
