If you don’t want to go all out on a flagship Samsung device, the Galaxy Grand series is always one of the next best options. Since it doesn’t have the power of the flagships, you want to gain root access and increase the power to get the most out of it. You can do that by overclocking the internal system with the help of apps from Google Play. You might also wish to increase the Samsung battery performance and remove the stock Samsung bloatware they always pre-install. Others might wish to try installing a custom ROM for the Grand Duos which is usually made by third-party developers. You can find some really great ROMs that will update the version of Android.

The best way to backup your Grand Duos after completing the guide is by installing a custom recovery and entering the recovery mode. From there you can choose to take a NANDroid backup before flashing a ROM. The NANDroid option is amazing since it takes nearly a complete snapshot of the current ROM. Usually you would need to download and install many apps from Google Play to backup all the different things a NANDroid can do at once.

However, that’s after you have root access. before you have root access, first you must take a backup the usual way. That means using the build-in Samsung backing up options, or installing third-party application from Google Play. Helium for Android is the best for backing up your apps, and it’s also great for backing up other data.

You will need to unlock the Developer Options menu if you cannot already see it available from the Settings menu on your Grand smartphone. Go to Settings > About Device or About Phone and tap over the build number seven times. if you forget to count, don’t worry. The display should tell you how many times you have left before the Dev Options is now unlocked. After it’s unlocked,. simply head back out of there and go back to the main home screen on the Android device,. Now tap to open the Settings once again and scroll down the list until you see the Developer Options menu.

Check the box that enables the USB Debugging Mode once you are inside the Developer Options menu. Now you can leave there and it will remember your Android OS preferences without having to click any confirmation box.
