Samsung's 2012 flagship smartphone, Galaxy S3 remains powerful even if tagged now as a "mid-range device" since Galaxy S4's launch. However, it comes with some flaws which were reported by many owners. Here are five commonly complained issues and tips to enhance the battery life of Samsung Galaxy S3.

Memory Insufficient Error

One of the most common issues reported by owners is the Insufficient Internal Memory Error. It is described as "there is not enough memory left" where apps are installed and usually happens when the owner attempts to reinstall an application.

How to Fix: Remove the ".odex" file inside the app's folder. You can use the "Lucky Patcher" to delete it effectively.

Error Code 97

Depending on your network carrier, Error Code 97 message means that the device can send everything else except text messages.

How to Fix: Go to the device's "Settings" and update the data profile. Reboot the phone and try sending another text message. You can also inquire with your network carrier to help you fix the problem.

No SIM Error

Sometimes, the Galaxy S3 displays "No SIM" even though there an actual SIM card inserted. According to experts, there are two possible reasons how this error happens:
a. Defective SIM card.

b. Loose connection between the handset and the SIM tray.

How to Fix: Try pushing a tiny sheet of paper between the SIM and the SIM tray or use an alternative SIM card instead. This error has nothing to do with locked or unlocked state of your Galaxy S3.

Message Application Error

The error indicates the owner that a message remains unread even if there isn't any. This problem may occur to any Samsung Galaxy S3 user and still unknown if the latest Android 4.1.2 update released by your network carrier has fixed the problem.

How to Fix: Simply press the "Home" key to solve the problem. If not, reboot the device and the false notification will disappear.

Over-the-Air Update Error

Usually occurs when the OTA update is almost completed which then aborts the entire process. No one definitely knows how the error happens or what reason might have caused it, even Samsung.

How to Fix: Use the Samsung Kies PC Suite instead of the Over-the-Air process or manually download then install the firmware if you are experienced on flashing ROMs.

Battery Tips for Samsung Galaxy S3

1. Disable push notifications and syncing of email & social accounts to improve battery life. Try changing interval time of syncing or turning it off altogether.

2. Do not let the battery drain itself or it will give a long term bad impact on the battery unit.

3. Use static wallpaper instead of live wallpapers to juice up more battery and put less stress on the overall performance.

4. Set the screen brightness to the lowest possible setting you can withstand or turn on the Automatic Brightness.

5. Turn off mobile data, Wi-Fi, Bluetooth and GPS when not in use.

6. Uninstall applications that are not necessary or you do not use to minimise apps eating away memory and battery.

7. Always update your device and apps installed on your phone. Updates may include bug fixes which may help the battery.
